Problems solved by technology

The reversing radar image cannot be displayed in the front-view single-view image, left-side single-view image and right-side single-view image mode, and the driver cannot use the reversing radar image to fully perceive the obstacles in the front and rear of the vehicle
[0005] It can be seen that in the prior art, radar images based on ultrasonic ranging can only be displayed in a single-view mode, and cannot be displayed when the single-view mode is switched to other modes, which is not convenient for the driver to fully control the surrounding areas of the car.

Embodiment 1

[0051] figure 1 A flow chart of a radar-based reversing method provided by Embodiment 1 of the present invention is shown.

[0052] Such as figure 1As shown, the method includes:

[0053] Step S110: Obtain multiple channels of image data information collected by multiple image acquisition devices located on the vehicle body, and synthesize a panoramic image corresponding to the above multiple channels of image data information.

[0054] Wherein, the image acquisition device specifically includes a wide-angle camera and an image data information acquisition component for acquiring multiple channels of image data information.

[0055] Usually the wide-angle camera is arranged on the front, rear, left and right sides of the car body, and the wide-angle camera captures images of the front, rear, left, and right sides of the car body. The image data information acquisition part converts the front, rear, left, and right images of the vehicle body simultaneously captured by the ...

Embodiment 2

[0065] figure 2 A flow chart of a radar-based reversing method provided by another embodiment of the present invention is shown. Such as figure 2 As shown, the method includes:

[0066] Step S210: Acquiring multiple channels of image data information collected by a plurality of image acquisition devices located on the body parts, and synthesizing a panoramic image corresponding to the above multiple channels of image data information.

[0067] The wide-angle camera captures the front, rear, left, and right images of the car body, and the image data information acquisition component converts the front, rear, left, right, left, and right images captured by the front, rear, left, and right wide-angle cameras into multiple image data information, and transmits the multi-channel image data information to the car. system. The vehicle-machine central control system acquires multiple channels of image data information, and performs synthesis processing on the multiple channels of...

Embodiment 3

[0084] image 3 It shows a schematic structural diagram of a radar-based reversing device provided in Embodiment 3 of the present invention, and the device includes:

[0085] The panoramic image generating module 31 is adapted to acquire multiple image data information collected by a plurality of image acquisition devices located at vehicle body parts, and synthesize a panoramic image corresponding to the multiple image data information;

[0086] The radar azimuth information determination module 32 is adapted to acquire radar data information collected by radar equipment located at the body part, and determine radar azimuth information corresponding to the radar data information;

[0087] The panoramic radar image generation module 33 is suitable for drawing the radar data information corresponding to the radar azimuth information on the panoramic image according to the radar azimuth information, so as to obtain the panoramic radar image for reversing, and display the panoram...

Abstract

The invention discloses a reversing method and unit based on a radar. The reversing method comprises the steps: multi-channel image data information collected by a plurality of image collecting devices located on a vehicle body is obtained, and a panoramic image corresponding to the multi-channel image data information is synthesized; radar data information collected by a radar device located on the vehicle body is obtained, and radar orientation information corresponding to the radar data information is determined; and according to the radar orientation information, the radar data informationcorresponding to the radar orientation information is drawn on the panoramic image, a panoramic radar image used for reversing is obtained, and the panoramic radar image is displayed on a prearrangeddisplay screen. According to the reversing method and unit, the radar data information obtained in an ultrasonic ranging mode is displayed in the panoramic image, a driver learns the situation of obstacles at all angles around a vehicle comprehensively through the radar data information superimposed panoramic radar image, and the problem that a single view requires frequent switching of view modes, and consequently the radar data information cannot be displayed continuously is avoided.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles, in particular to a radar-based reversing method and device. Background technique [0002] Along with economic growth and automobile price reduction, automobile has been popularized, and the problem of reversing is becoming more and more prominent. The traditional car reversing warning system superimposes the radar image based on ultrasonic ranging by superimposing the rear-view single-view image to help the driver check the rear of the car during the reversing process. [0003] However, during the reversing process, the driver keeps switching single-view images in various directions in order to check the situation around the vehicle. In the front-view single-view image, left single-view image and right single-view image mode, the reversing radar image cannot be displayed, and the driver cannot use the reversing radar image to perceive obstacles in the front and rear of the vehicle in all dire...
