Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0059] According to one or more embodiments, a start-stop sign detection system for vehicle chassis dynamic detection includes a target detection model and a vertical sign classification model.

[0060] Through the target detection model and the vertical sign classification model, a global detection is performed on whether there are start and stop signs in the entire state image of the acquired target vehicle's chassis dynamic detection;

[0061] Segment the state image in which the start and stop signs are not detected by the global detection into a plurality of local area images and perform local detection of the start and stop signs again;

[0062] When it is detected that there is a start-stop mark in the whole state image or any local area image, stop the detection and output the detection result that there is a start-stop mark; otherwise, output the det...

Abstract

The invention discloses a start-stop sign detection system and a start-stop sign detection method for dynamic detection of a vehicle chassis, and relates to the vehicle detection field. The system andthe method solve the problems that a traditional detection method of a start-stop sign for vehicle chassis dynamic detection is high in labor cost and low in efficiency, the long-time repeated detection operation is easy to cause adverse states such as fatigue, inattention and the like of detection personnel, the detection accuracy is affected and the like in the prior art. According to the technical scheme, a target detection model based on deep learning is used for carrying out start-stop sign detection judgment on images obtained from a server and used for carrying out start-stop sign detection on vehicle dynamic detection start/end. According to the start-stop sign detection system and the start-stop sign detection method for the dynamic detection of the vehicle chassis, whether the start-stop sign exists or not when the chassis starts or ends dynamically is detected automatically, so that the requirements for high efficiency and high accuracy of annual inspection work of the vehicle are met.

Description

technical field [0001] The invention relates to vehicle detection, in particular to a start-stop mark detection system and method for vehicle chassis dynamic detection. Background technique [0002] With the continuous development of social economy and the continuous improvement of people's living standards, the number of urban motor vehicles has increased rapidly. The workload of the annual inspection of motor vehicles has also increased rapidly. In the process of vehicle annual inspection, the traditional detection of start and stop signs for vehicle chassis dynamic detection is mainly through manual detection, but this method has high labor costs, low efficiency, and long-term repetitive detection operations are likely to cause fatigue to the inspectors , Inattention and other bad states affect the detection accuracy. [0003] How to accurately and quickly detect the start and stop signs used for the dynamic inspection of vehicle chassis, while avoiding the disadvantage...
