Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] The human visual color space (HSL color space or HSI color space) is an intuitive representation of the characteristics of human vision, reflecting the way humans perceive and experience colors. The color classification recognition method proposed by the present invention is described by taking an HSL color space image as an example. If the output image of the camera is an RGB color space image, it needs to be converted to an HSL color space ima...

Abstract

The invention provides a color classification and recognition method, device and automatic driving system. A method for classify and identifying color includes such steps as converting target image tobe identified into HSL color space image, performing chromatographic conversion to obtain chromatographic spectrum of target image to be identified. Performing similarity measurement on chromatogramsand chromatograms of a plurality of preset color categories to obtain chromatographic similarity scores of the chromatograms and each preset color category; Each similarity score is compared with a preset threshold value, and a preset color category corresponding to the similarity score greater than the preset threshold value is determined to be a color category of the target image to be recognized. In the technical proposal of the invention, firstly, the chromatogram of the target to be identified is obtained, and then the chromatogram of the target to be identified and the known category chromatogram are subjected to similarity measurement, and when the similarity score is greater than a given threshold value, the target to be identified is judged to be the known color category.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a color classification recognition method, device and automatic driving system. Background technique [0002] In practical applications, it is usually necessary to classify or identify objects according to their colors. For example, color comparison analysis can be performed on the images of standard samples of known categories and the target to be identified, and the target can be classified or identified according to the similarity of their colors. [0003] Usually, the output image of the camera is a grayscale image or a color image in RGB color space. The grayscale image has too little information, resulting in low recognition accuracy; and the RGB color space does not conform to human visual habits, and is not suitable for color recognition. [0004] Therefore, in the prior art, there is a problem of inaccurate color recognition caused by the RGB color space being unsuitabl...
