Title: VEHICLE BODY COLOUR IDENTIFICATION METHOD AND DEVICE
Abstract:
Provided are a vehicle body colour identification method and device, for solving the problem that the accuracy of vehicle body colour identification is low when a vehicle body is affected greatly by illumination. The method comprises: performing a histogram equalization operation on a first image on a value (V) channel of a hue-saturation-value (HSV) colour space to acquire a second image, wherein the first image includes image information about a target vehicle (S11); sliding a set window according to a set sequence to divide the second image into a plurality of different regions (S12); determining first colour features corresponding to the plurality of different regions (S13); and according to the determined first colour features corresponding to the plurality of different regions and according to a pre-set algorithm, determining the vehicle body colour of the target vehicle (S14). Since a histogram equalization operation is performed on a first image on a V channel, and a vehicle body colour is identified in accordance with the determined different first colour features, the accuracy of the vehicle body colour identification is improved.
