Abstract
A method and an apparatus for processing surrounding images of a vehicle are provided. In the method, plural cameras disposed on the vehicle are used to capture images of plural perspective views surrounding the vehicle. The images of the perspective views are transformed into images of a top view. An interval consisted of at least a preset number of consecutive empty pixels is found from one column of pixels in each image of the top view, and the images of the perspective views and the top view are divided into floor side images and wall side images according to the height of the interval in the image. The divided floor side images and wall side images are stitched to generate a synthetic image surrounding the vehicle.

A method for processing surrounding images of a vehicle, applicable to an electronic apparatus disposed on a vehicle, wherein the electronic apparatus is coupled to a plurality of cameras disposed on the vehicle, the method comprising:
- capturing images of a plurality of perspective views surrounding the vehicle by using the cameras;
- transforming each of the images from the perspective view into a top view;
- finding an interval consisting of at least a preset number of consecutive empty pixels from one column of pixels in each of the images of the top view, and dividing the images of the perspective views and the top view into floor side images and wall side images according to a height of the interval in the image;
- and
- stitching the divided floor side images and wall side images to generate a synthetic image surrounding the vehicle.
An apparatus for processing surrounding images of a vehicle, comprising:
- a connection device, connecting to a plurality of cameras disposed on the vehicle;
- a storage device, storing a plurality of modules;
- and
- a processor, coupled with the connection device and the storage device, loading and executing the modules in the storage device, wherein the modules comprise:
- an image capturing module, capturing a plurality of images of perspective views surrounding the vehicle by using the cameras;
- a view transformation module, transforming each of the images from the perspective view into a top view;
- an image dividing module, finding an interval consisting of at least a preset number of consecutive empty pixels from one column of pixels in each of the transformed images of the top view, and dividing the images of the perspective views and the top view into floor side images and wall side images according to the height of the interval in the image;
- and
- an image stitching module, stitching the divided floor side images and wall side images to generate a synthetic image surrounding the vehicle.
