Abstract
A method for estimating the total vehicle mass of freight vehicles based on image recognition is implemented with the help of a camera installed on the vehicle and a processing unit equipped with a vehicle total vehicle mass estimation system in order to improve the safety technology level of the freight vehicle itself. The processing unit estimates the total vehicle mass of the freight vehicle by calculating the area of the white dotted line graphic captured by the camera during the vehicle's driving process occupied by the entire picture. The total vehicle mass data can be obtained only through the camera and software system. The hardware cost is very low, and the camera can use the cameras of other auxiliary driving systems in the vehicle, so the material cost of estimating the total vehicle mass is basically zero.
