Cam_scale_vertical_tc_percentage will define how much tilt needs to be corrected for in

percentage terms. When used in conjunction with cam_scale_vertical_tc_stretch_factor,

which will stretch the image vertically.

The effect of using cam_scale_vertical_tc_mode can be seen below.

Vertical plane is tilted-away from

the camera – therefore the bottom

row of image represents the

nearest point. The nearest point

appears bigger in the uncorrected

image, therefore top/bottom ratio

will be greater than 1.0

Vertical plane is tilted-towards the

camera – therefore the top row of

image represents the nearest point.

The nearest point appears bigger in

the uncorrected image, therefore

the top/bottom ratio with be less

than 1.0

Case1: CAM_SCALE_VERTICAL_TC_PERCENTAGE = 10%

Case2: CAM_SCALE_VERTICAL_TC_PERCENTAGE = -10%
