The invention discloses a parking space size recognition system and method based on a 360-degree look-around camera. The system comprises a central controller, an image collection module, an image processing controller, a wireless transmission controller and a database. When the intelligent automobile carrying the system is automatically parked, the 360-degree look-around camera is used for shooting images of the idle parking space and the parking space where the automobile is parked. The image processing controller carries out image processing; respectively obtaining the length-width ratio ofthe idle parking space and the length-width ratio of the vehicle in the parking space to the parking space; and through an recognition matching technology of the image processing controller, the shotimage of the vehicle is analyzed and matched with the vehicle information in the database, the brand model of the vehicle is intelligently identified, the external size (length and width) of the vehicle is obtained, and then the size (width and depth) of the parking space is obtained through simple proportion conversion. The system is high in applicability, high in recognition rate and capable ofgreatly improving the parking space size recognition precision during parking.
Description
technical field [0001] The invention belongs to the field of automatic parking, and in particular relates to a vision-based parking space size recognition system and method. Background technique [0002] With the development of the city, the urban land use planning is becoming more and more rigorous, and the parking spaces are becoming narrower and narrower. In order to find an efficient parking solution and reduce driver fatigue, an automatic parking system has emerged. Among them, the parking system based on ultrasonic radar is The mainstream technical solution in the parking space recognition technology, but due to the large ultrasonic scattering angle and poor directionality of the ultrasonic radar, when measuring a distant target, the echo signal will be relatively weak, which will affect the measurement accuracy, so the parking space cannot be obtained. Accurate size information. [0003] In addition, the parking space recognition can also be realized through the came...
