Adding GoPro Camera Profiles to Tower & Mission Planner

Posted on

We sell cameras for surveying, namely GoPro Heros and our MAPIR line. Neither of these (modified) cameras are listed as a camera in the drop-down of Mission Planner or Tower, so in order to calculate the overlap during a survey mission the program needs to know what camera you’re using. Here’s how to add a custom camera depending on which program you’re using and what lens:

 

Mission Planner:

  1. Find your Mission Planner install folder: C:\Program Files (x86)\Mission Planner
  2. Locate file named “cameras.xml” and open in text editor (Notepad)
  3. Add below text before/after any of the <Camera></Camera> sections

GoPro + 3.97mm Lens:

<Camera>
<name>GoPro 3.97mm 12MP</name>
<flen>3.97</flen>
<imgh>3000</imgh>
<imgw>4000</imgw>
<senh>4.686</senh>
<senw>6.284</senw>
</Camera>

GoPro + 4.35mm Lens:

<Camera>
<name>GoPro 4.35mm 12MP</name>
<flen>4.35</flen>
<imgh>3000</imgh>
