Embodiment Construction

[0020] figure 1 It is a schematic diagram of a multi-eye camera system. Such as figure 1 As shown in , a multi-eye camera system 100 includes N lenses (L 1 to L N ), which individually transmits captured images to N image signal processing units (ISPU 1 to ISPU N )110. The image signal processing units 110 process the images captured by the lenses to improve image quality. Individual image signal processing unit (ISPU 1 to ISPU N ) 110 processed image is sent to a wide-angle image generator 120. The wide-angle image generator 120 includes a multiple image automatic exposure (AE) matching unit 122 for reducing the chromatic aberration problem between images taken under different light environments; Connecting point search and connecting operation. Finally, a wide-angle image can be output.

[0021] Next, refer to Figure 2 to Figure 5 To illustrate the fast dynamic connection point search method according to the present invention, wherein figure 2 It shows the flo...

Abstract

The invention discloses a rapid dynamic image-jointing point searching method of a multi-eye camera chain. The block matching is performed in a search window which is determined by a camera angle, the object distance and the expected accuracy of an image-jointing point, so as to reduce the computational complexity for the known image-jointing point searching method and find out and adjust the image-jointing point dynamically and rapidly.

Description

technical field [0001] The present invention relates to image splicing of wide-angle images; more specifically, relates to a method for quickly and dynamically finding out appropriate splicing points of multiple images. Background technique [0002] It is a commonly known technique to generate wide-angle (panoramic) images by seamlessly joining individual images together. This technology is usually limited to the splicing of images of distant objects, or can only perform splicing for targets at a certain fixed distance, but cannot be used for complex images of dynamic objects with different distances (or images of short-distance objects) Find out the appropriate connection point to execute the connection. This is because the splicing of such complex images requires relevant information about the distance between the object to be photographed and the camera. In order to obtain the correct value of the above distance, quite complicated and time-consuming calculation work is ...
