Claim 6:
7. The method for intelligently measuring vehicle trajectory based on a binocular stereo vision system according to claim 1, wherein the distance measurement method of the binocular stereo vision system in step 5 comprises the steps of: calculating the distance di of all the N matching points respectively; calculating the mean value m and the standard deviation s of di; calculating the Z score Zi for each matching point:, μ
