Distance measurement using image processing
显示 更早的评论
I have to calculate distance and velocity of a vehicle moving towards me by using image processing technique by comparing the images taken consequently by the camera which i have fitted in the robot. Is there any possibility to achieve the above requirement by using matlab.. please help me with suggestion..

Dear Kumar,
Mathworks provides a toolbox (the Computer Vision System Toolbox) that lets you track the object. When you click on 'Camera Calibration' you can find information how the camara has to be calibrated such that distances can be calculated.
If for example it is given that the object moves towards the camera, the change in the size of the object (which can be calculated with MATLAB) is related to the frontal velocity of the object. If hereby the size of the object is known, the frontal speed could be calculated. (v=ds/dt, where ds can be expressed by the area change of the object)
Good luck! Christiaan

Thanks in advance !!
