Embodiment Construction
[0017] figure 1 It is a structural schematic diagram of an image and laser composite remote sensing road surface monitoring automatic alarm system of the present invention.
[0018] The real-time reminder method for speed limit on complex roads is characterized in that it is implemented according to the following steps:
[0019] (1) Detection of abnormal road conditions: use sensors to detect abnormal road conditions that affect driving speed; and capture road surface image information;
[0020] (2) Calculate the degree of influence: the abnormal condition of the road surface combined with the image information of the road surface to convert the ice and snow coverage rate to determine the degree of influence of the abnormal condition on the driving speed;
[0021] (3) Calculate the speed limit value: according to the road management regulations, convert the speed limit value under this abnormal situation;
[0022] (4) Real-time warning of speed limit: synchronously display t...
