Embodiment Construction

[0011] Such as figure 1 Shown is a truck overload monitoring system based on monitoring video involved in this embodiment, including: a vehicle object detection module, a tire status acquisition module, a load conversion module, a vehicle type identification module, an overload judgment module, and a vehicle type database, wherein: vehicle The target detection module acquires the image of the target truck in the video and outputs it to the tire status acquisition module. The tire status acquisition module performs feature extraction on the tire area to obtain the pixel distance between the car bodies as a feature and outputs it to the load conversion module. The load conversion module bases the feature and Calculate the actual deformation information of the tire with reference to the object, and the vehicle type recognition module obtains the image of the target vehicle according to the vehicle target detection module, and then binarizes the image, and finally compares the vehi...

Abstract

The invention discloses a truck overload monitoring method and system based on a monitoring video. Vehicle target detection is carried out in a video file to obtain a target truck image; feature extraction is carried out on the tire areas to obtain pixel distances between vehicle bodies as features; and then calculating tire actual deformation information and a truck type based on the characteristics and the reference object, obtaining vehicle checking load information through a vehicle model database, and judging according to the tire actual deformation information and the vehicle checking load information to obtain an overload result. The distance between the truck body and the wheels is measured through video processing, the measured distance is compared with the normal distance betweenthe truck body and the wheels, and whether the truck is overloaded or not is judged.

Description

technical field [0001] The present invention relates to an application in intelligent transportation, in particular to a method and system for monitoring overloading of trucks on roads by processing road monitoring videos. Background technique [0002] Traditional monitoring stations mainly use static weighing and dynamic weighing methods to measure the truck load. In the existing new technology, the magnetic resistance sensor is used to measure the distance between the truck suspension and the axle, and the distance between the truck suspension and the axle and the truck load By establishing a mathematical model, the truck load and overload detection results can be obtained. Compared with the traditional weighing method, it is simpler and easier to implement. However, it is unavoidable to install sensors, and the possibility of man-made damage to sensors is extremely high, requiring human supervision. [0003] There is an existing method for judging vehicle overload by an...
