Anti-collision early warning system and method based on 360-degree look-around input

Abstract

The invention discloses an anti-collision early warning system based on 360-degree look-around input. The anti-collision early warning system comprises a look-around fisheye camera, a vehicle-mountedsensor unit, a control module and an early warning and reminding module. The look-around fisheye camera is used for collecting image information around a vehicle; the vehicle-mounted sensor unit is used for collecting vehicle signals; and the control module is connected with the look-around fisheye camera and connected with the vehicle-mounted sensor unit, receives the vehicle signals and / or the image information, performs analysis and process, and outputs an early warning signal. The warning and reminding module receives the early warning signal. The anti-collision warning system is mainly aimed at the conditions that pedestrians / bicycles passing through the front and rear of the vehicle transversely and bicycles passing through the blind area on the right side of the vehicle in the samedirection have possible collision with the vehicle; through video intelligent analysis and processing, the pedestrian collision prevention and protection functions are integrated into a look-around system; and the active / auxiliary safety performance of the 360-degree look-around system is improved in the way of auxiliary display and early warning.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to an anti-collision warning system and method based on 360-degree surround view input. Background technique [0002] Intelligence is one of the important trends in the development of the automotive industry today, and vision systems are increasingly used in the field of vehicle active safety. The 360-degree surround view system is one of the existing advanced automotive auxiliary safety systems. This type of system can provide the driver with an auxiliary display of the surrounding conditions of the vehicle under low-speed conditions, and provide visual assistance for the driver's low-speed operations (such as parking, etc.). It has become a standard configuration on many mass-produced models. There are still many deficiencies in the existing mass production systems: (1) Most of them only provide a plan view of the surrounding environment of the vehicle from a top-down perspectiv...

Problems solved by technology

[0003] A technical problem solved by the present invention is: the 360-degree surround view system can only assist in displaying the area within 2-3 meters around the vehicle, and the object mapping deformation of the non-road plane part of the auxiliary display is serious, and the resolution of the long-distance target of the surround-view fisheye camera is limited Moreover, the object distortion at the edge of the scene is relatively obvious; without active safety functions, pedestrian / bicycle detection and tracking cannot be performed.
