A method for detecting the S-shaped driving behavior of vehicles in the weighing area of ​​a dynamic flat scale

Abstract

The invention discloses a method for detecting the S-shaped driving behavior of a vehicle in a weighing area of ​​a dynamic flat scale. Including: use the camera on the side of the road to collect the image of the flat scale area, input the contour abnormality detection neural network for analysis; when the contour is normal, input the flat scale area image into the flat scale perception neural network to obtain the flat scale semantic segmentation map; use the edge contour map And the edge-aware neural network of the flat scale performs edge perception on the semantic segmentation map of the flat scale, and obtains the distribution map of the edge points of the flat scale; performs straight line fitting on the edge points, and performs perspective transformation to obtain a top view of the edge line of the flat scale; detects and collects car images The wheel landing point in the vehicle; the detected coordinates of the wheel landing point and the top view of the edge line of the flat scale are transformed into the same coordinate system, and according to the positional relationship between the wheel landing point and the edge line of the flat scale, it is judged whether the car has an S-shaped driving behavior. The invention can accurately identify the S-shaped driving behavior of the weighing vehicle.

Description

technical field [0001] The invention relates to the fields of artificial intelligence and automobile dynamic weighing, in particular to a method for detecting S-shaped driving behavior of automobiles in the weighing area of ​​a dynamic flat scale. Background technique [0002] Dynamic weighing of the car, that is, the weight of the car can be obtained by driving directly from the flat scale without stopping the car. Due to visual errors, the scale operator cannot accurately observe the position of the car on the electronic scale. The driver takes advantage of this. When weighing on the narrow strip flat scale, the car turns an S-curve and takes an S-shaped route, allowing the car to take one wheel. On the road, only one wheel is on the flat scale, thereby reducing the actual weight of the car when weighing. Some methods detect the position of the car through an infrared beam detector to determine whether the car has an S-shaped driving behavior. The infrared beam detector i...
