There's a good guide here http://www.mapir.camera/blogs/guide/48987139-adding-the-mapir-camera-to-mission-planner-and-tower It's specific for mapir cameras, but if you know the parameters for your camera it should work

I think there is a problem in his xml. Under Mission planner : Survey2 + 3.97mm Lens (Standard Lens Included):

<Camera>
<name>Survey2 3.97mm 16MP</name>
<flen>3.97</flen>
<imgh>4608</imgh>
<imgw>3456</imgw>
<senh>6.17472</senh>
<senw>4.63104</senw>
</Camera>

Under Tower : Survey2:

<cameraInfo>
<Name>Survey2 16MP</Name>
<SensorWidth>4.608</SensorWidth>
<SensorHeight>3.456</SensorHeight>
<SensorResolution>16</SensorResolution>
<FocalLength>3.97</FocalLength>
</cameraInfo>

Sensor width and height does not have the same size in Mission planner and Tower for the same camera ! It's a non sense. It should be this in Tower : 

<cameraInfo>
<Name>Survey2 16MP</Name>
<SensorWidth>4.63104</SensorWidth>
<SensorHeight>6.17472</SensorHeight>
<SensorResolution>16</SensorResolution>
<FocalLength>3.97</FocalLength>
</cameraInfo>

well spotted...I've emailed the people at Mapir to confirm. Will post their reply here when it comes. Thanks for pointing it out! I am also uncertain why the height is greater than the width, as in normal camera orientation (i.e. with the shutter button at the top) the width of the image & sensor must be greater than the height??

I tell him on mapir facebook, his answer bellow :

MAPIR Camera Looks like one of the sensor size numbers are swapped. Width is always larger than height. We'll get it swapped on the site shortly. Thanks

Th sensor height and sensor weight seems to be pixels divided by 1000 !
