Coal gangue recognition method and device

The invention provides a coal gangue recognition method and device, and relates to the technical field of coal automatic recognition. The method comprises the following steps: collecting the number of pixels in target area image data, a picture size and a picture resolution; calculating the area value of coal gangue and the area value of raw coal in the target region according to the number of pixels in the target region image data, the picture size and the picture resolution; and calculating the weight value of the coal gangue and the weight value of the raw coal in the target area according to the area value of the coal gangue and the area value of the raw coal in the target area. The problem that the weight value of the coal gangue and the weight value of the raw coal in the coal and the proportion cannot be accurately judged can be solved. 本公开提供一种煤矸石识别方法及其装置，涉及煤炭自动化识别技术领域。该方法包括：获取目标区域图像数据中的像素个数、以及画面尺寸和画面分辨率；根据目标区域图像数据中的像素个数、以及画面尺寸和画面分辨率，计算目标区域的煤矸石的面积值和原煤的面积值；根据目标区域的煤矸石的面积值与原煤的面积值，计算目标区域的煤矸石的重量值与原煤的重量值。本公开
