Hi 374823146340,
I’ve been looking into it for some time now but sadly haven’t found the answer as of yet. I now understand what parameters are required to calculate a frustrum volume in which I can detect if a given point of a pointcloud is within it.
for FOV calculation I know know that the sensor width and height, image resolution, pixel ratio, focal length and lens focal are used to determine the FOV. Which indeed can be derived from picture information.
However at this moment I am still not sure what information the last few columns of data within the Internal/External camera .csv file export are.
- #Name: Name of the image
- x,y,z: position within the 3D space
- alt,heading,pitch: translation of the camera
- f: focal distance (distance between the lens and camera, I assume it has been calculated by RC itself)
And then some for me unknown variables:
- px, py
- k1,k2,k3,k4
- t1, t2
I was hoping you or someone else could shed some light on these last few parameters. Thanks in advance!
