<h2>Pag-kalibrate ng Camera<a class="headerlink" href="#calibrating-the-camera" title="Permalink to this headline">¶</a></h2>
|

<p>Ang pag-calibrate ng camera ay isang malaking hamon sa mga pangkaraniwang camera. Ang mga pagbabago sa temperatura, mga vibrations, pokus, at iba pang mga kadahilanan ay maaaring makaapekto sa mga hango na mga parameter na may malaking epekto sa resultang data. Ang awtomatikong o pag-calibrate sa sarili ay posible at mas mainam sa mga drone flights, ngunit depende sa pattern ng flight, ang awtomatikong pagkakalibrate ay maaaring hindi mag-alis ng lahat ng pagbaluktot sa mga nagresultang produkto. Sa papel nina James at Robson (2014) na "Ang pagpapalit ng sistematikong error sa mga topographic models na nagmula sa UAV at ground ‐ based image networks <<a class="reference external" href="https://onlinelibrary.wiley.com/doi/full/10.1002/esp.3609">https://onlinelibrary.wiley.com/doi/full/10.1002/esp.3609</a>> ay nagpapakita kung paano mabawasan ang pagkabaluktot.</p>

<p>Ang epekto ng "Bowling" sa point cloud ng mahigit "13,000+ imahe na nakalap ng World Bank Tanzania sa bahaing lugar ng Msimbasi, Basin, Dar es Salaam, Tanzania.</p>
|
||
<p>Upang pagaanin ang epekto na ito, may ilang mga pagpipilian ngunit ang pinakasimple ay ang mga sumusunod: lumipad ng dalawang pattern na pinaghihiwalay ng 20°, at sa halip na magkaroon ng isang nadir (tuwid at pababang pagturo) camera, gumamit ng isa na nakakiling sa harap ng 5°.</p>

|
||
</div>
|
||
<p>Dahil ang pamamaraang ito sa paglipad ay maaaring mas matagal kaysa sa mga karaniwang lipad, ang isa o ilang mga piloto ay maaaring lumipad ng isang maliit na lugar gamit ang pamamaraan sa itaas. Ang OpenDroneMap ay bubuo ng isang pangkalibrate file na tinatawag na mga cameras.json na pagkatapos ay mai-import upang magamit na pang calibrate ang isa pang flight na mas mahusay na napaliparan.</p>
|
||
<p>Bilang kahalili, ang sumusunod na pamamaraan ng eksperimento ay maaaring gawin: lumipad na may mas mababang overlap, ngunit dalawang flight ng crossgrid (kung minsan ay tinatawag na crosshatch) na pinaghiwalay ng 20° na may 5° pasulong na nakaharap na camera.</p>
|
||
<ul class="simple">
|
||
<li><p>Ang mga porsyento na overlap ng crossgrid ay maaaring mas mababa kaysa sa mga kahilera na flight. Upang makakuha ng mahusay na mga resulta ng 3D, kakailanganin ang 68% na magkakapatong at sidelap para sa katumbas na 83% na magkakapatong at sidelap.</p></li>

<li><p>Upang makakuha ng magandang resulta ng 2D at 2.5D (digital elevation model), kakailanganin ang 42% na magkakapatong at sidelap para sa isang katumbas na 70% na magkakapatong at sidelap.</p></li>

<p>Bilang default, ang ODM ay hindi lumilikha ng DEM. Upang lumikha ng isang digital na modelo ng terrain, siguraduhing ipasa ang watawat --dtm. Upang lumikha ng isang digital na modelo ng ibabaw, siguraduhing ipasa ang watawat --dsm.</p>

|

<p>Para sa pag gawa ng DTM, ginagamit ang isang Simple Morphological Filter (smrf) upang mauri ang mga puntos sa nasa lupa kumpara sa wala sa lupa, kung saan ang mga nasa lupa na puntos lamang ang ginagamit. Ang filter na "smrf" ay maaaring kontrolin sa pamamagitan ng maraming mga parameter:</p>
|
||
<blockquote>
|
||
<div><ul class="simple">
|
||
<li><p>"--smrf-scalar" halaga ng pag-iskala. Taasan ang parameter na ito para sa mga lupain na may maraming pag-iba ng taas.</p></li>
|
||
<li><p>"--smrf-slope" parametro ng libis, na sukat ng "tolerance ng slope". Taasan ang parametrong ito para sa mga lupain na may maraming pagiiba-iba ng taas. Dapat ang halaga nito ay mas mataas sa 0.1 ngunit hindi tataas sa 1.2.</p></li>
|
||
<li><p>"--smrf-threshold" bingit ng pagtaas. Itakda ang parametrong ito sa minimong taas (sa yunit na metro) ng mga bagay na wala sa lupa.</p></li>
|
||
<li><p>"--smrf-window" parametro ng pinakalamaking paikot na sukat (sa yunit na metro) na sukat ng pinakamalaking bagay (gusali, mga puno, atbp.) na aalisin. Dapat itakda sa halagang mas mataas sa 10.</p></li>

|
||
<p>Ang pagpapalit ng mga opsiyon na ito ay nagreresulta ng malaking epekto sa DTMs. Ang pinakamahusay na basahin para mapagkunan ng pinakamahusay na impormasyon ukol sa parametro ng epekto ng output ay ang <a class="reference external" href="https://www.researchgate.net/publication/258333806_An_Improved_Simple_Morphological_Filter_for_the_Terrain_Classification_of_Airborne_LIDAR_Data">An improved simple morphological filter for the terrain classification of airborne LIDAR data</a> (Ang PDF ay libre lamang)</p>
|

<p>Ang <code class="docutils literal notranslate"><span class="pre">--smrf-threshold</span></code> ang may pinakamalaking impact sa resulta.</p>
|
||
<p>Ang SMRF ay mahusay sa pagiwas ng Type I na pagkakamali (maliliit na numero ng ground poins na napagkakamalan bilang non-ground) pero "acceptable" sa pagiwas sa Type II na pagkakamali (malaking numero na non-ground points na napagkakamalan na ground). Ito ay dapat na bigyan importansiya kapag bumubuo ng DTMs na hangarin na gamitin ng biswal, bilang ang mga baga na napagkakamalan na ground ay mukhang artifacts sa resulta ng DTM.</p>

<p>Weather conditions modify illumination and thus impact the photography results. Best results are obtained with evenly overcast or clear skies. Also look for low wind speeds that allow the camera to remain stable during the data collection process.
|
||
In order to avoid shadows which on one side of the stockpile can obstruct feature detection and lessen the number of resulting points, always prefer the flights during the midday, when the sun is at the nadir so everything is consistently illuminated.
|
||
Also ensure that your naked eye horizontal visibility distance is congruent with the planned flight distances for the specific project, so image quality is not adversely impacted by dust, fog, smoke, volcanic ash or pollution.</p>

</div>

<div class="section" id="flight-pattern">
|
||
<h3>Flight pattern<a class="headerlink" href="#flight-pattern" title="Permalink to this headline">¶</a></h3>
|
||
<p>Most stockpile measurement jobs does not require a crosshatch pattern or angled gimbal as the resting angle of stockpile materials allows the camera to capture the entire stockpile sides. Only some special cases where erosion or machinery operations causes steep angles on the faces of the stockpile would benefit of the crosshatch flight pattern and angled camera gimbal but consider that these additional recognized features come at a cost, (in field labor and processing time) and the resulting improvements are sometimes negligible.</p>
|
||
<p>In most of the cases a lawn mower flight pattern is capable of producing highly accurate stockpile models.</p>
|
||
<div class="figure align-center">
|
||
<img alt="a simple lawnmower flight pattern can produce accurate results" src="../_images/lawnmower_pattern.png" />

</div>
|
||
<p>Recommended overlap would be between 75% and 80% with a sidelap in the order of 65% to 70%. It is also recommended to slightly increase overlap and sidelap as the flight height is increased.</p>

||
</div>
|
||
<div class="section" id="flight-height">
|
||
<h3>Flight height<a class="headerlink" href="#flight-height" title="Permalink to this headline">¶</a></h3>
|
||
<p>Flight height can be influenced by different camera models, but in a general way and in order to ensure a balance between image quality and flight optimization, it is recommended to be executed at heights 3 to 4 times the tallest stockpile height. So for a 10 meter stockpile, images can be captured at a height of 40 meters.
|
||
As the flight height is increased, it is also recommended to increase overlap, so for a 40 meter height flight you can set a 65% sidelap and 75% overlap, but for a planned height of 80 meters a 70% sidelap and 80% overlap allowing features to be recognized and properly processed.</p>

<h3>GCPs<a class="headerlink" href="#gcps" title="Permalink to this headline">¶</a></h3>

<p>To achieve accuracy levels better than 3%, the use of GCP’s is advised. Typically 5 distributed GCP are sufficient to ensure accurate results.

When placing or measuring GCP, equipment accuracy should be greater than the GSD. Survey grade GNSS and total stations are intended to provide the required millimetric accuracy.</p>

|

<p>Also consider that once the limits of the stockpile are set in software like <a class="reference external" href="https://www.qgis.org">QGis</a>, you will find there are some ways to determine the base plane. So for isolated stockpiles which boundaries are mostly visible, a linear approach can be used. While for stockpiles set in slopes or in bins, the base plane is better defined by the lowest point.

<p>For carefully planned and executed projects, and specially when GSD is less than 1 cm, the expected accuracy should be in the range of 1% to 2%.
|
||
The resulting accuracy is comparable to the commercially available photogrammetry software and the obtained using survey grade GNSS equipment.</p>

<p>Ang docker ay may kahina-hinayang na gamit ng space at by default ay hindi naglilinis ng sobrang laman na data at machine kapag ang proseso ay kumpleto na. Ito ay may benepisyo kapag kailangan na puntahan ang proseso na matagal ng terminated pero kinakarga pa rin ang bigat ng nagamit na storage space overtime.

<p>Ang <a class="reference external" href="https://www.opendronemap.org/">OpenDroneMap</a> ay hindi naman laging epektibo sa pagset-up locally-ito ay makapagyarihan na machine sa pagproseso ng malalaking datasets ng sa gayon ang cloud machine ay maaaring masagot ang mga tao sa field. Ngunit, bandwidth ang problema sa maraming low-income na setting. Ang kakulangan na ito ay hindi mareresolusyonan agag-agad pero ang mga sumusunod na hakbang ay makatutulong sa pagpapababa ng kailangan na bandwidth para maproseso ang drone imagery datasets sa cloud mula sa African na lokasyon.</p>
|
||
<p>Dito ay nagsasaad kami ng nakakalito ngunit maisasagawa na proseso para makagawa ng OPenDronMap cloud machine (<em>hindi</em> CloudODM ito, isa lamang cloud-based instance ng ODM na pwedeng patakbuhin mula sa command line) at gamitin ito para maproseso ang malalaking photo sets. Ito ay nangangailangan nga kaalaman sa Unix command line use, ssh, Digital Ocean account (ang Amazon AWS ay gagana ngunit mga kaunting kaibahan sa set-up), at katamtaman na kaalaman sa general computer literacy. Kung ikaw ay hindi masyadong eksperto at handang pagdaanan ang nakakalito na pagset-up, ang 'CloudODM <<a class="reference external" href="https://www.opendronemap.org/cloudodm/">https://www.opendronemap.org/cloudodm/</a>>`__ ang dapat pagbasehan.</p>
|
||
<p>Ang kabuoan na proseso ay nakatarget sa pagpapalipad ng mga importanteng misyon sa African o kapareho na lokasyon na maghahanap ng ipoproseso na data habang naghihintay ng field setting. Sa madalit sabi, ito ay naglalayon ng trabaho na makababawas sa bandwidth/data transfer, kesa sa simlpeng pagpapatakbo lamang ng ODM.</p>

<p>Nirerequire ng ODM na iset-up ang direktoryo sa machine. ANg kritikal ay ang install folder (kung ininstall mo katulad ng nasa taas, <code class="docutils literal notranslate"><span class="pre">/home/odm/ODM/</span></code>) at ang project folder (i.e. <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/</span></code>)</p>
|

<ul class="simple">
|
||
<li><p>Ang ODM settings.yaml file ay nag-specify ng isang parent directory na naglalaman ng lahat ng proyekto. Ito ang nangyayari sa path line ng proyekto ng settings.yaml file (medyo nakakalito ito ngunit ito ang <em>parent</em> diirectory ng mga indibidwal na direktoryo ng proyekto na tinutukoy sa project name parameter kapag tinatawagan ang ODM). Ang edit settings.yaml at ang set ng project_path parameter sa (ayon sa halimbawa na set-up) <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/</span></code>, na sa kaso na ito ay pinupunto ang volume na nilikha. Ang Indibidwal na direktoryo ng proyekto ay nilikha sa loob nito.</p></li>
|
||
<li><p>Ang mga indibidwal na direktoryo ng proyekto, halimbawa <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/</span></code> ay naglalaman ng gcp_list.txt file, ang imahe na image_groups.txt file, at ang imahe ng folder kada proyekto```</p></li>
|
||
<li><p>Ang folder ng imahe, i.e. <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/images/</span></code> ay naglalaman ng lahat ng imahe. Kapag sinet-up ito ng ganon, hindi marere-copy ang mga imahe dahil ito ay nasa direktoryo na kung saan gusto sila ilagay ng ODM.</p></li>
|
||
<li><p>I-modify ang settings.yaml para matukoy ang parent directory ng project folder (sa kaso na ito ang Volume na nilikha, <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/</span></code>). Siguraduhin na ang mga imahe ay nasa tamang lugaw, i.e. <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/images</span></code> at ang ibang ancillary files <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/images</span></code> ay nasa root folder <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/</span></code></p></li>
|
||
<li><p>Kung ang mga imahe mo ay nasa hiwalay na folder para sa indibidwal na AOI blocks or flights (na kadalasan ay nangyayari kapag ang iyong pamamahala ay organisado), pwedeng gumawa ng image_groups.txt file na may incantation na <code class="docutils literal notranslate"><span class="pre">for</span> <span class="pre">i</span> <span class="pre">in</span> <span class="pre">*;</span> <span class="pre">do</span> <span class="pre">cd</span> <span class="pre">$i;</span> <span class="pre">for</span> <span class="pre">j</span> <span class="pre">in</span> <span class="pre">*;</span> <span class="pre">do</span> <span class="pre">echo</span> <span class="pre">"$j</span> <span class="pre">$i"</span> <span class="pre">>></span> <span class="pre">../$i.txt;</span> <span class="pre">done;</span> <span class="pre">cd</span> <span class="pre">../;</span> <span class="pre">done;</span></code> at <code class="docutils literal notranslate"><span class="pre">cd</span> <span class="pre">../</span></code>, <code class="docutils literal notranslate"><span class="pre">for</span> <span class="pre">i</span> <span class="pre">in</span> <span class="pre">myproject/*.txt;</span> <span class="pre">do</span> <span class="pre">cat</span> <span class="pre">$i</span> <span class="pre">>></span> <span class="pre">image_groups.txt;</span> <span class="pre">done;</span></code>. Ito ay makakabuo ng file na may tamang istraktura: listahan ng mga imahe at "group name" pagkatapos ng bawat isa (na sa kaso na ito madalas ay pangalan ng folder na pinanggalingan nito). Ilagay ang lahat ng image files sa isang direktoryo na tatawagin na images sa project root dir (so <code class="docutils literal notranslate"><span class="pre">/mnt/odmdata/myproject/images/</span></code>). Ang image_groups.txt file ay papayagan ng ODM na bantayan ang mga imahe na na kasapi ng kaparehong batch, kahit na sila ay nasa iisang direktoryo lamang.</p></li>
