I would like to calculate the horizontal and vertical field of view from the camera intrinsic matrix for the cameras used in the kitti dataset. If your image is portrait or square: Then i looked at the picture from the webcam and marked the edges of the image with a pen on the paper (click for original resolution).

If your image is landscape: Just set the wanted value in the fov field. So for example, for a 35mm film (frame is 24mm x 36mm), and a 20mm (focal length) lens, the horizontal fov would be almost 84 degrees. To specify the horizontal fov:

If you want to have horizontal fiels of view instead of vertical you need this formula: I found that in the c160 (field of view = 50°).

If you have a fixed sensor size, altering the focal length will alter the afov and therefore the overall fov. To specify the horizontal fov: Camera.fieldofview = horizontalfieldofview * (16f/9f) / ( (float)camera.pixelwidth / camera.pixelheight); Since the equation for field of view contains the sensor width, which determines the crop factor of a sensor, this is another way to see.

For a normal lens, the diagonal (or horizontal or vertical) field of view can be calculated as: Wide angle of views capture greater areas, small angles smaller areas. From this definition, it can be shown that the afov of a lens is related to the focal length ( equation 1 ), where f f is the focal length and h.

The camera's sensor is 6.35mm (1/4 inch according to doc), so if it holds to standard 3:2, then the vertical is about 4.23mm.
