Problems solved by technology

Among them, compared with other methods, ultrasonic has strong penetrating power, small attenuation, strong reflection ability, insensitive to light, color, electromagnetic field, not easily affected by bad weather, simple ranging principle, high ranging accuracy, low cost, etc. However, ultrasonic waves do not have obvious advantages in identifying the number, position, and shape of obstacles; machine vision can intuitively display the number and relative position of debris around the vehicle by virtue of the combination of cameras and display screens. and its shape, but the ranging accuracy achieved by the monocular / binocular vision ranging algorithm cannot meet the needs of the automatic parking system

Abstract

The invention discloses an automatic parking system. The automatic parking system comprises a hardware system and a software system. The automatic parking system comprises the hardware and software systems which are based on an ultrasonic ranging basic principle and combine camera information, and adopts an ultrasonic data processing method, an image processing method and an information combination method which are all independently researched and developed, so that a current position, a target position (namely a parking lot) and surrounding environmental parameters of a car are obtained, a driver is reminded to notice the surrounding environmental situations of the car through the modes of voice reminding, color warning and the like, and meanwhile, a car parking path is planned, and the car is parked into the parking lot automatically. By adopting the automatic parking system, the driver does not need to look on each direction when parking the car, and safety hidden dangers are eliminated, so that car driving is safer, more convenient and rapid and more intelligent.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to an automatic parking system, and is especially suitable for an automatic parking system with an ultrasonic sensor fused with a camera. Background technique [0002] Along with the development of society, the quantity of automobile is constantly increasing, and the traffic accident that is caused by parking is also increasing day by day, has become an indisputable fact. Therefore people have put forward higher requirement to the convenience of car manipulation, hope that a kind of device can solve the inconvenience that car parking brings to people, eliminates unsafe factor in driving. The automatic parking system can solve the above difficulties. It improves the intelligence level and safety of the vehicle, reduces the difficulty of parking for the driver, and improves the safety and driving comfort of the driver. [0003] At present, the obstacle data information obtaine...
