Changing VideoCamera field of view

[thushv89]

Hi, I would like to know if there is a way to change the field of view of the video camera. I want an wide-angle image of my robot's view.

I tried tweaking cam_width and cam_height but had no luck!

My script for camera looks like this

camera = VideoCamera()
camera.translate(x = 0.5, z= 0.6)
camera.rotate(y = -0.13)
camera.properties(cam_width=1024,cam_height=256,cam_far=500)
camera.frequency(5)
atrv.append(camera)
camera.add_interface('ros',topic='/camera')

MORSE version: 1.3 Blender version: 2.69.0 Python version: 3.4.3

Thank you

So after playing with this issue for a while, I found a hack. So, if you move the camera to the back of your robot and set cam_near high enough so your view is not obstructed by the robot, for example,

camera.translate(x = -1.5)
camera.properties(cam_near=1.5)

then you can simulate the wide-angle effect.

But I'm not sure, if there's a more clever legitimate way of doing this. So I'm leaving the issue open.

The KX_Camera seems to have a .fov member, so I think you can change the field of view using this field. Unfortunately, for the moment, there is no interface for that in Morse.

try changing the focal length with:

camera.properties(cam_focal = 1)

To convert the cam_focal parameter to opening angle: arctan(cam_focal / 16)

Yup, reducing cam_focal did the trick. Thanks everyone. Really appreciate it. :) Closing the issue
