Abstract
A method of vehicle monitoring includes: obtaining a frame of an image before exposure; outputting a luminance value of each partition of the image, accumulation number of pixels lower than a first set threshold, accumulation number of pixels higher than a second set threshold, to generate an evaluation data; generating eigenvalues of a plurality of illuminance evaluation areas based on the evaluation data and the preset illuminance evaluation area distribution table; estimating the illuminance of an environment of a vehicle according to the eigenvalues of the plurality of illuminance evaluation areas and differentiation characteristics between normal illuminance and low illuminance; switching the region of interest of a current exposing image based on the estimating results, generating a weight table based on the content of the current exposing image and the switched region of interest, controlling the exposing of the region of interest based on the weight table.
