The embodiment of the invention discloses an elevator full-load detection method based on image recognition, which comprises the following steps of: 1, arranging a reference scale on the wall of an elevator car, arranging a camera in the elevator car, and determining actual coordinate data of the reference scale and the wall of the elevator car under a camera coordinate system; 2, images in the elevator car are collected in real time, and the images are processed to obtain processed images; step 3, contours of the reference scale, the elevator car wall and the areas corresponding to people or objects in the elevator car are obtained, and pixel coordinates and actual coordinates of pixel points on the contours are determined; and 4, judging whether full load exists or not. According to the method, the full load is judged by calculating whether people can stand in the elevator car or not through image recognition, the problem that various actual full loads cannot be recognized through existing weight detection is solved, and the situation that the elevator stops layer by layer due to actual full load is avoided; in addition, the method can be directly realized based on a monitoring camera in an existing elevator car, and the cost is low.
本发明实施例公开了一种基于图像识别的电梯满载检测方法,包括:步骤1:在电梯厢壁上设置参照标尺,在电梯厢内设置相机,确定参照标尺、电梯厢壁在相机坐标系下的实际坐标数据;步骤2:实时采集电梯厢内的图像,对图像进行处理得到处理后的图像;步骤3:得到参照标尺、电梯厢壁以及电梯厢内的各人或物对应区域的轮廓,确定轮廓上各像素点的像素坐标和实际坐标;步骤4:判断是否满载。本发明通过图像识别来计算电梯厢内是否还可站人来判断是否满载,解决了现有的重量检测无法识别很多种实际满载的问题,避免出现实际满载但是电梯层层停靠的情况;此外,本发明可直接基于现有的电梯厢内的监控相机实现,成本低。
