Two frames in a video sequence were taken at times 1.6s and 2.0s. The point (145,100,t1) in the rst image has been found to correspond to the point (140,100,t2) in the second image. Given that the centre of the image is at pixel coordinates (185,100), and the focal length of the camera is 30mm, the pixel size of the camera is 0.1mm/pixel, calculate the depth of the identied scene point. Assume: a) the camera was moving at 0.40 m/s along its x-axis; b) the camera was moving at 1.00 m/s along its z-axis.

What is the Depth of the point at 2.0s if camera moving along x-axis?(2dcp)

What is the Depth of the point at 2.0s if camera moving along z-axis?
