Embodiment 1

[0020] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a vehicle-based image processing method according to the present invention, which may specifically include the following steps:

[0021] In step 102, the radars are used to detect each spliced ​​public area respectively.

[0022] The 360 ​​panoramic assisted parking system can be equipped with cameras and radars. For example, a laser radar sensor can be used to obtain a 360-degree panoramic image without blind spots through the camera and radar, providing a reference for the driver's driving. Among them, the system installs a camera on the front, rear, left, and right sides of the car, that is, a total of four cameras are installed, such as figure 2 shown. According to the direction, the images captured by the cameras can be spliced ​​in pairs to finally generate a panoramic stitched image. There is a common area when the two images are stitched together, that is, the area captured by both ...

Embodiment 2

[0031] refer to image 3 , which shows a flow chart of steps of another embodiment of a vehicle-based image processing method according to the present invention, which may specifically include the following steps:

[0032] In step 302, radar is used to scan each mosaic common area.

[0033] Step 304, analyzing the returned radar data to detect whether there are obstacles in each stitched public area.

[0034] For the on-board radar configured on the vehicle, the on-board radar will detect and scan the surroundings of the vehicle. When stitching images around the vehicle, the on-board radar can be used to scan each spliced ​​public area. The radar receives the returned radar data, and then the radar The data is analyzed, such as determining the distance and direction of the reflected target through the radar echo in the radar data, and detecting whether there are obstacles in each stitching public area.

[0035] If yes, that is, there is an obstacle in any of the stitched pub...

Embodiment 3

[0058] On the basis of the above embodiments, this embodiment also provides a vehicle-based image processing device.

Abstract

The present invention provides a vehicle-based image processing method and device to prevent splicing from being affected by the parallax of obstacles. The method includes: respectively detecting each mosaic public area by radar; when an obstacle is detected on the predetermined mosaic line of the mosaic public area, adjusting the corresponding predetermined mosaic line of the mosaic public area; adopting the adjusted The stitching line performs image stitching, resulting in a panoramic stitched image. Eliminate the influence of obstacles on the splicing by adjusting the splicing line, improve the splicing effect, and provide accurate information about the surrounding conditions of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a vehicle-based image processing method and device. Background technique [0002] The 360 ​​panoramic assisted parking system obtains images around the car in real time through four cameras installed on the front, rear, left, and right sides of the car, and then stitches the four images together through the on-board processor to form a 360-degree panoramic image without blind spots. By observing the panoramic image, the driver can grasp the surrounding conditions outside the car in real time and reduce the occurrence of accidents. [0003] Among them, the four images collected by the four cameras need to be spliced ​​and fused to form a panoramic image. The usual splicing method is to splice two adjacent images, and the splicing line of the adjacent images is the diagonal line of the four common areas, that is, the diagonal line is the splicing line to splice and fuse t...
