问题
I am trying to reproduce the google street view camera in my rendering software.
But I think that some parameters are missing because the result has a problem (scale or field of view distorsion ?).
What I know :
- camera position : I set it (latitude/longitude).
- horizontal fov + pitch + heading : given by google API.
But the real focal length is missing i.e. the sensor size or the crop factor or the focal length mutiplier. (different words for the same thing I think).
Do you know if google provide this parameter ?
If not did somebody find a good approximation ?
Thanks.

Does this help? http://davidpapp.com/2014/04/27/specs-of-a-google-street-view-car/ I'm looking for the information also. Based on what we see here, it looks like its 5.1mm focal length.
