The invention discloses a vehicle over-limit alarm system based on a laser vision fusion algorithm. The method comprises the steps that S1, a camera and a radar are used for collecting information of a road section in front of a vehicle; s2, preprocessing the image acquired by the camera; s3, inputting the processed image into a laser vision fusion algorithm to detect a height limiting rod or a culvert; s4, outputting 3D position information of two vertexes of the height limiting rod or the culvert through an algorithm; s5, calculating the length and the width of the height limiting rod or the culvert according to the 3D position information of the two vertexes obtained in the step S4; s6, comparing the length and the width of the height limiting rod or the culvert obtained in the step S5 with the length and the width of the vehicle, and judging whether the vehicle can pass or not; executing S7 when the vehicle cannot pass, and executing S1 when the vehicle can pass; and S7, if the vehicle cannot pass, prompting and alarming. The laser vision fusion algorithm model is adopted to identify the height limiting rod or the culvert and measure the length and the width of the height limiting rod or the culvert, and the detection precision is greatly improved while identification is carried out.

    一种基于激光视觉融合算法的车辆超限报警系统,包括步骤:S1:使用相机与雷达采集车辆前方路段信息;S2:对相机采集到的图像进行预处理;S3:将处理后的图像输入到激光视觉融合算法中检测限高杆或涵洞;S4:算法输出限高杆或涵洞的两个顶点3D位置信息;S5:根据步骤S4中得到的两个顶点3D位置信息计算限高杆或涵洞的长和宽;S6:根据步骤S5得到的限高杆或涵洞的长和宽与车辆的长宽比较,判断车辆是否能够通过;当判断车辆不能通过时执行S7,能够通过时执行S1;S7:车辆不能通行,提示报警。本发明通过采用激光视觉融合算法模型对限高杆或涵洞进行识别并测量其长度与宽度,在进行识别的同时还极大提高了检测精度。
