Long-distance automatic parking system and method based on multi-sensor fusion

Abstract

The invention discloses a long-distance automatic parking system and method based on multi-sensor fusion. The system comprises a central data processing module, a path planning module, a mapping module, a parking module, a communication module and a control unit. The sensor comprises but is not limited to an IMU, a vehicle-mounted all-round looking camera, an ultrasonic wave radar and a binocular camera. According to the embodiment of the invention, through planning paths for the obtained parking lot map, obstacle information, parking place information and road information within a vehicle running range are judged according to a disparity map obtained by the binocular camera and are fed back to the central data processing module in real time; and after calculation, the central data processing module gives an instruction to the control unit so as to realize long-distance automatic parking of vehicles from entering the parking lot to parking in the parking place.

Description

technical field [0001] The invention relates to a system and method for long-distance automatic parking based on multi-sensor fusion. Background technique [0002] In recent years, with the rapid growth of the national economy, the rapid progress of society and the continuous enhancement of national strength, great changes have taken place in people's working and living environment. The urban population is becoming more and more dense, and there are more and more families with private cars. However, the parking spaces in the parking lot are limited, and car owners often spend a lot of time looking for parking spaces. This does not match the fast-paced urban life, so a fast and effective automatic parking method. At the same time, long-distance autonomous parking, as an important part of autonomous driving, is also an important part of road intelligent transportation. At present, there is no unified and effective long-distance autonomous parking solution. Although a plan t...

Problems solved by technology

We have proposed an automatic parking system based on stereo vision positioning and mapping before, but as far as the current technology is concerned, it is still difficult to solve the problem of automatic parking with a pure machine vision solution. For example, there may be calculation errors, visual Blind spots etc.
