Claim 10:
11. The vehicle according to claim 9, wherein the operation of,
by performing the predetermined processing to the image in the image database that corresponds to the object to be identified, obtaining the three-value-processing coefficient further comprises:
performing grayscale processing to the image in the image database that corresponds to the object to be identified, to obtain a grayscale map of the image data;
performing three-value processing using a plurality of different test thresholds to the grayscale map, to obtain a plurality of test three-value-processed images containing pixel data of the object to be identified;
according to a preset pixel quantity and a preset pixel-occurrence probability, determining pixel quantities of the plurality of test three-value-processed images;
according to the pixel quantities of the test three-value-processed images, acquiring a cumulative differential-value distribution probability of the pixel data; and
according to the cumulative differential-value distribution probability, acquiring the three-value-processing coefficient.
