Design And Implementation Of Intelligent Parking Control System Based On Multi Sensor Data Fusion

Nowadays,the car is moving in the direction of security,intelligence and other direction.The advanced technology combines the control theory,artificial intelligence,machine vision,data fusion,multi-sensor and other related fields,so the intelligent parking system is still one of the hot spots in the field of vehicle driving.The technical difficulty lies in whether parking can be accurately found parking spaces to determine whether the parking conditions to meet the parking conditions and can be completed in a relatively small space parking to reduce the actual parking process the incidence of collision accidents.In this paper,in order to better improve the precise detection of parking spaces,put forward the relevant theoretical algorithms and methods and hardware experimental platform.The multi-sensor data fusion technique based on similarity is adopted in this paper to fuse the data detected by multiple ultrasonic sensors,so as to improve the success rate of parking spaces.For the parking spaces with parking lines,this paper is based on image processing parking spaces detection and marking,the main camera is collected to correct the video image to extract the parking spaces of the special identifier,then based on the camera projection principle,Parking spaces to be calibrated to get the test vehicle and the parking spaces between the vertical distance.After t he vertical distance between the test vehicle and the parking space obtained by ultrasonic distance measurement or camera projection calibration,the path planning of the parking space is started and the necessary parameters of each movement phase are calculated.In order to verify the algorithm and the reliability of the method,this paper presents the overall design of vehicle control system hardware design,including the production of vehicle model,sensor selection,vehicle control system design,information data processing.Finally,the control system of the intelligent parking is built on the experimental vehicle,and the algorithm and the whole scheme are verified.The hardware design scheme and software architecture are introduced in detail for the three parts of the car control system: the sensor connection circuit,the control syste m circuit and the information processing circuit.The test and analysis of the intelligent parking system designed for this topic can improve the recognition rate of the parking spaces adequately for the small parking spaces without parking lines,and can realize precise parking for the parking spaces with parking lines through the cameras.So after the experimental analysis,fully verify the theory of the subject algorithm,for solving practical problems have great practical significance.
