Hello everyone ,i have captured car positons at differents frames.http://www.imagesup.net/pt-7140205392313.png%5D%5BIMG%5Dhttp://www.imagesup.net/dt-7140205392313.png

Suppose car's(left side car which is coming towards us) centroid is at video frame1 is P(x1,y1) and Q(x2,y2) at video frame4.

1.Is it possible to represent P and Q points into 3D? so that i can calculate correct pixel distance d(PQ)?

Note:u can assume that camera is stationary, placed at height 10 m from ground level .u can also assume any suitable data if u want
