Problems solved by technology
[0004] However, in the process of dynamic weighing, due to unmanned supervision and law enforcement at the detection site, the vehicle will cheat through the non-linear and uniform driving trajectory when passing the detection area, which reduces the measurement of the weighing equipment and affects the vehicle weighing. heavy accuracy

Embodiment approach
[0033] In one embodiment, the above-mentioned step 103: calculating the running trajectory of the vehicle under test according to the video image, there may be various implementations, for example, the following processing may be performed:
[0034] 301: After determining that the vehicle under test enters the weighing area according to the video image, cut and position the video image, and determine the license plate position of the vehicle under test;
[0035] 302: Determine the movement track of the license plate;
[0036] 303: Determine the moving track of the license plate as the running track of the vehicle under test.

The embodiment of the invention provides an anti-cheating dynamic vehicle weighing method and an anti-cheating dynamic vehicle weighing device. The method comprises the following steps: acquiring a video image of a tested vehicle in a weighing area and load information of a weighing sensor through which the tested vehicle passes; calculating the weight of the tested vehicle according to the load information; calculating the running track of the tested vehicle according to the video image; and correcting the weight of the tested vehicle according to the running track of the tested vehicle to obtain the corrected weight of the tested vehicle. According to the method, the weighing result can be corrected according to the running track of the vehicle when the tested vehicle bypasses and deviates from the running track, the weighing accuracy of the tested vehicle is ensured, and the cheating behavior of the tested vehicle in the weighing process is eradicated.
Description
technical field [0001] The invention relates to the field of dynamic vehicle weighing, in particular to an anti-cheating dynamic vehicle weighing method and device. Background technique [0002] With the rapid development of my country's economy, the construction of highways is also developing rapidly, but the problem of vehicle overloading and exceeding the limit is further aggravated. Vehicle overloading has a serious impact on public transport safety. Highway management departments use methods such as off-site law enforcement and over-limit detection to restrict vehicle over-limit behavior, use economic means to curb overload and over-limit phenomena, reduce damage to multiple road facilities for overloaded and over-limit vehicles, and improve road safety. Among them, the most widely used overrun detection method is dynamic weighing. [0003] The dynamic weighing of the vehicle is generally obtained by calculating the axle load of each axle of the vehicle, and then addi...
