Embodiment Construction

[0056] see figure 1 , the present invention consists of a video acquisition unit 100, a circular video synthesis unit 200, and a display control and storage unit 300 to form a 360-degree circular video synthesis method.

[0057] see figure 2 , the car overlooks and the camera includes an ultra-wide-angle fisheye camera 101 at the front grid, an ultra-wide-angle fisheye camera 102 on the left rearview mirror, an ultra-wide-angle fisheye camera 103 on the right rearview mirror, and an ultra-wide-angle fisheye camera on the top of the rearview mirror. The fisheye camera 104, the ring video synthesis unit 200, and the display control and storage unit 300 are located on the front panel of the driver. In relatively dark occasions, such as low-light application environments at night, the short-range infrared LED lights around the camera will be automatically controlled by the photosensitive device to turn on and off.

[0058] see image 3 , the ring video synthesis unit adopts FL...

Abstract

The invention discloses a method for synthesizing annular video of 360 degrees for assistant drive of a vehicle. The method adopts a video acquisition unit, an annular video synthesis unit and a display control and storage unit, and has the characteristics of reliable stability, low cost and suitable batch production. The method can acquire video signals in real time for four super-wide-angle fish-eye cameras arranged at front, back, left and right of the vehicle, carries out treatment of fish-eye image correction, annular image mosaic and vision angle conversion on four channels of the video signals through a video decoding unit and a video synthesizing control unit to generate a panoramic displayed plan view of 360 degrees, achieves multiple display modes through the display control and storage unit, and can selectively store correlated video information. The method can provide surrounding scenes for a driver, and eliminate vision blind area thereof, and is favorable for the driver to achieve safe and accurate vehicle driving operations. The method is used for assistant drive for sedans, business vehicles and heavy trucks of various grades, and passenger coaches of different types.

Description

technical field [0001] The invention belongs to the field of motor vehicle assisted driving and video monitoring, and relates to a technology for simultaneous shooting and real-time video processing by four cameras on the front, rear, left, and right sides of the vehicle, and in particular to a 360-degree circular video synthesis method, which is applicable to various grades of vehicles Assisted driving of cars, commercial vehicles, trucks, and different types of passenger cars. Background technique [0002] Automobiles have become a major means of transportation in modern society, and people have put forward higher requirements for the safety and comfort of driving. The original idea of ​​the invention of the car rearview mirror is to facilitate the driver to see the situation on both sides and behind the car, prevent collisions with the outside world during the reversing process, improve the safety of driving and the third party outside the car, and prolong the service lif...
