Background
Along with the formal implementation of the national road traffic safety law and the road traffic safety law implementation regulations, the control of vehicle overload and overload has been gradually deepened into the heart of people. The national standard GB1589-2016 limit values of the overall dimensions, axle loads and mass of automobiles, trailers and automobile trains, which is officially released and implemented in 2016, sets the standard of overrun and overload. In the same year, the "over-limit transportation vehicle driving road management regulation" (2016 (62) in the department of transportation) issued by the department of transportation and the "implementation comments (trial) on the unified law enforcement and standardization work for governing vehicle over-limit and overload" (2017) issued by the department of transportation and the public security department in 2017 explicitly stipulate that the "axle type" (including the number of axles, the number of driving axles and the arrangement mode) is taken as the standard for determining the over-limit and overload of the freight vehicle. Therefore, accurate identification of the number of vehicle axles and acquisition of the axle parameters such as the drive shaft are important prerequisites for determining overrun overload.
The existing axle recognition device is generally fixed on the left side or the right side of a lane, a laser scanner or a line camera and the like in the device are utilized to scan the side information of a vehicle body, and the side image information is processed by relying on a three-dimensional point cloud or an image recognition technology to calculate the number of axes and the type of the axes. The mode does not directly collect the axle information of the vehicle chassis, the side axle information of the vehicle body is limited, and the side protection device shields the axle from the oblique rear part, so that the collected information cannot be reliably identified and the calculation error is large.
Or optical equipment such as a laser scanner or a linear array camera embedded in a lane is adopted to acquire chassis information, side image information is processed by means of a three-dimensional point cloud or image recognition technology to calculate the number of axes and the type of the axes, or filtering and waveform feature recognition technologies are utilized to determine the number of the axes and the type of the axes. However, the existing axle recognition device is easily affected by external environments, such as rain, snow, wind, sand, ground sundries, etc., and if the recognition window of the axle recognition device is shielded or stains are left on the recognition window, the recognition effect is seriously affected, and the problem of inaccurate recognition is caused. The identification window is usually cleaned manually, and although some axle identification devices are cleaned by blowing air, the fan needs to be operated for a long time to ensure the cleaning effect, which is not beneficial to the long-term use of the device.
