Problems solved by technology

Although this method has no effect on flat roads, when there are three-dimensional objects on the road, the objects will be stretched seriously, seriously affecting the driver's observation of road conditions
And the closer to the edge of the image, the more severe the stretching, which also greatly limits the visual range of the top view

Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] At present, in the planar panoramic image, the fisheye camera is mainly used for image acquisition, so as to ensure the characteristics of ultra-wide angle. However, if figure 1 As shown, because the fisheye camera has a strong refractive index for light, and the closer to the edge of the lens, the greater the refractive index, the greater the distortion.

[0028] The inventors of the present invention found that, due to the large distortion of the fisheye lens, what is captured is a distorted image shrinking around the c...

Abstract

The invention discloses a method, a device and a vehicle for generating a panoramic image of a vehicle. The method for generating a panoramic image of a vehicle includes: respectively acquiring multiple preset directions around the vehicle collected by multiple vehicle-mounted camera devices on the vehicle. image; according to the pre-established distortion image mapping table, the images in the plurality of preset directions are respectively mapped to the preset theoretical spherical surface to obtain a plurality of spherical images on the theoretical spherical surface; for the plurality of Image fusion is performed on the spherical image to generate a spherical panoramic image of the vehicle. The embodiment of the present invention can effectively solve the problem of object stretching when mapping the image onto a plane, thereby better restoring the intersections around the vehicle, facilitating the driver to observe, and increasing the visual field of view of the overlooking interface, making driving Drivers can see more of the road conditions, improving safety.

Description

technical field [0001] The present invention relates to the technical field of vehicles, in particular to a method, a device and a vehicle for generating a surround-view panoramic image of a vehicle. Background technique [0002] The plane panoramic image uses two calculation processes of distortion correction and perspective transformation to correct and transform the images obtained by the cameras installed around the car, and splice the generated overhead images in all directions around the vehicle to obtain a panoramic overhead image. Although this method has no effect on flat roads, when there are three-dimensional objects on the road, the objects will be stretched severely, seriously affecting the driver's observation of road conditions. And the closer to the edge of the image, the more severe the stretching, which also largely limits the viewing range of the top view. Contents of the invention [0003] The present invention aims to solve one of the technical proble...
