Intelligent detection system and method of refitted exhaust fan of car

Abstract

The invention discloses an intelligent detection system and method of a refitted exhaust fan of a car. A system structure thereof includes a target detection module, a target image similarity judgement module and a statistical analysis module. The target detection module includes a vehicle target detection unit and an exhaust-fan target detection unit. The vehicle target detection unit is used foracquiring a vehicle area image. The exhaust-fan target detection unit is used for detecting the vehicle area image and identifying an exhaust fan. The target image similarity judgement module is usedfor comparing feature vectors of exhaust-fan images. The statistical analysis module judges a detected structure according to checking criteria, and returns a reason of checking failure. The system and method are mainly applied to refitted-exhaust-fan detection of the car in vehicle annual-inspection of motor vehicles, realize entire-process automatic-checking in a detection process, can return afailed detected image and the reason to a server at the same time to save the same for later evidence collecting, save manpower, and also guarantee fairness and openness of checking work.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence judgment for annual inspection of motor vehicles, in particular to an intelligent detection system and method for an exhaust fan refitted on a car. 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. As an important traffic participant, motor vehicles must have good safety and reliability. However, some motor vehicle owners have weak safety awareness and illegally modify motor vehicles. Illegally modified vehicles that have not passed safety tests may increase the probability and severity of traffic accidents. Therefore, it is very important to strictly detect whether the vehicle is modified to maintain traffic safety. [0003] Traditional exhaust fan detection is mainly done manually. This method has high labor costs and low efficien...

AI Technical Summary

Problems solved by technology

[0003] Traditional exhaust fan detection is mainly done manually. This method has high labor costs and low efficiency, and long-term repetitive calibration operations are prone to fatigue, negligence and other bad conditions, which affect the calibration accuracy.

[0004] How to accurately and quickly check whether the vehicle is equipped with an exhaust fan, and at the same time avoid the disadvantages of high cost of manual calibration, fatigue, and negligence, etc., is a technical problem that continues to be solved
