Problems solved by technology

[0003] In the prior art, image recognition or temperature sensor measurement is often used to determine the icing condition of the road surface. However, since the road surface is not covered with water, there is basically no difference between the icy road surface and the normal ice-free road surface, and it is difficult to use image recognition. Identify whether the road surface is icy, and the judgment of the icy condition of the road surface is limited by environmental conditions
However, the temperature sensor is used to measure the temperature of the road surface. The temperature measurement area on the ground is a single point. The measurement results are accidental, and the temperature sensor is not in direct contact with the road surface. The measurement results are greatly affected by the air temperature. For example, the air temperature is affected by light, humidity and Due to the influence of wind speed and other reasons, even if the road surface temperature is too low and there is icing, the measurement result of the temperature sensor is still 5-8 degrees Celsius. The error of using the temperature sensor to measure the ground temperature is relatively large, which may easily lead to wrong judgments on the icing situation on the road surface

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computer applications, and in particular to a ground icing prediction method, device, electronic equipment, and storage medium. Background technique [0002] The driving safety of expressways has been widely concerned. In winter or in severe cold areas, the icy road surface of the expressway will greatly reduce the friction between the vehicle tires and the road surface, and reduce the braking safety distance of the vehicle. The risk of overturning and vehicle collision poses a huge threat to the safety of vehicles and personnel. Therefore, it is necessary to determine the icing condition of the expressway pavement in time. [0003] In the prior art, image recognition or temperature sensor measurement is often used to determine the icing condition of the road surface. However, since there is no water accumulation on the road surface, there is basically no difference between the ...
