Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Such as figure 1 As shown, a panoramic assisted driving method proposed in the first embodiment of the present invention includes:

[0043] Step S101, by detecting and obtaining real-time image information around the current vehicle through the cameras installed in the front, rear, left and right directions of the current vehicle;

[0044] In this embodiment, a fisheye camera is respectively installed at the four positions of the front face of the vehicle, rearview mirrors on both sides, and the rear license plate. The image can obtain the real-time fisheye perspective image information around the vehicle without dead angle, and can obtain the normal perspective image through de-distortion and correction.

[0045] Step S102, performing vehicle recognition on the detected real-time normal perspective image inf...

Abstract

The invention discloses a panoramic auxiliary driving method and system. The system comprises a detecting module, an identifying module, a calculating module and a display module. According to the system, all-round real-time images around a vehicle without a dead angle through fisheye cameras mounted in the front direction, the rear direction, the left direction and the right direction of the vehicle can be obtained; four images can be calibrated to normal angle images combing with parameters of the fisheye cameras calibrated in advance; surrounding vehicles can be identified real-timely through a vehicle identification algorithm; then the position of a current vehicle on a current lane can be calculated through a lane test algorithm; finally, according to a certain scaling factor, relative position information between the current vehicle and the surrounding vehicles and the current lane is simulatively displayed on the central control display with an overlook angle; therefore, a driver can clearly see the relative position of the current vehicle among the surrounding vehicles through a 360 degree of panoramic display, so that the driving safety of the driver is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a panoramic driving assistance method and system. Background technique [0002] At present, the common ADAS (Advanced Driver Assistance System) is mainly aimed at the recognition of the distance and lane in front of the vehicle. Its recognition angle range is limited, and it cannot fully assist the driver in driving operations. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention proposes a driving assistance method and system capable of 360-degree (or top view, or eagle-eye view) panorama detection, so as to improve the driving safety of the driver. [0004] In order to achieve the above object, the present invention proposes a panoramic assisted driving method, including: [0005] Through the cameras installed in the front, rear, left and right directions of the current vehicle, the real-time image information a...
