This paper presents a location method fusing color and edge feature

and the object authenticity confirmation method using the feature of concomitant and complement

to solve the problem of vehicle license plate location under complex environment. The area of license plate has fixed color assortment and rich character edge feature. For this point

the paper shows the algorithm of feature fusion to select all possible objects. And the object authenticity confirmation implements the location with feedback and it is suitable for the multi-object or multi-type objects location under complex environment. The experiments on actual RGB color images show the effective and robustness.
