System and method for detecting water depth of road surface in front of automobile

Abstract

The invention discloses a system and a method for detecting the water depth of a road surface in front of an automobile. The system comprises a control module, a water depth detection module, visual acquisition equipment and a warning unit. The water depth detection module is used for carrying out data scanning on the road surface on which the vehicle runs to generate a first three-dimensional model, carrying out data scanning on the waterlogged road surface to generate a second three-dimensional model, and comparing the two three-dimensional models to obtain waterlogged depth data. The visual acquisition equipment is used for preliminarily detecting a waterlogged road surface; the method comprises the following steps: carrying out data scanning on a traveled road surface to generate first point cloud data, and further establishing a first three-dimensional model; and performing data scanning on the waterlogged road surface to generate second point cloud data, and further establishing a second three-dimensional model. And fitting the first three-dimensional model and the second three-dimensional model to obtain accumulated water depth data. The accumulated water depth can be accurately calculated, the water depth condition of the road in front of the automobile is judged for a user in advance, and losses caused by automobile flooding are avoided.

Description

technical field [0001] The application belongs to the technical field of safe driving of vehicles, and in particular relates to a system and method for detecting the water depth of a road ahead of a vehicle. Background technique [0002] At present, with the improvement of people's economic level and living standard, the number of car ownership is also increasing. At the same time, due to the changes in the natural environment in recent years, flood disasters have occurred frequently, and the drainage systems in most cities are insufficient to cope with it, which has also led to serious water accumulation on urban roads and frequent flooding of vehicles. The water depth detection equipment is mainly for wading detection, and the accuracy of the water depth detection is poor, and the risk of flooding of cars still exists. In the prior art, most of the detectors installed outside the vehicle are used to detect the distance between the reference position of the vehicle and the...

Problems solved by technology

At the same time, due to the changes in the natural environment in recent years, frequent floods have occurred, and the drainage systems of most cities are not enough to deal with it, which has also caused serious water accumulation on urban roads and frequent incidents of flooded vehicles. The water depth detection equipment is mainly for wading water detection, the accuracy of water depth detection is poor, and the risk of car flooding still exists

In the prior art, the distance between the reference position of the vehicle and the horizontal plane is detected by the detector installed outside the vehicle, and the depth of the accumulated water is further obtained. The disadvantage is that the vehicle is already in the wading water, and then the detection is performed.

Limited by accuracy and other emergencies, the existing technology cannot predict the depth of the water in advance, and cannot effectively avoid the flooding of the car. There is an urgent need for a new method to judge the depth of the water in front of the car in advance before the car wades into the water. , so as to help the driver judge in advance whether the conditions for continuing to drive are met
