System and method for positioning color block region of 24-color card quickly and automatically

Abstract

The invention discloses a system and a method for positioning a color block region of a 24-color card quickly and automatically. The system comprises a jump point counting unit and a coordinate calculation unit, wherein the jump point counting unit is used for counting jump points on a bitmap formed by a taken photo; and the coordinate calculation unit is connected with the jump point counting unit, and is used for calculating a starting vertical coordinate and the side length of a color block by using a continuous and discontinuous law of the jump points in the vertical direction and calculating a starting horizontal coordinate of the color block by using the emergence location of the jump points in the horizontal direction so as to calculate the coordinates of the 24-color card region, so that quick and automatic positioning for the color block region of the 24-color card is realized. According to the scheme, the side boundary of each color block in the vertical direction is enabled to be prominent through image processing, and thus the region of each color block is automatically calculated quickly and accurately, so that manual operations for an interface frame are avoided, and the manpower and the time are saved. In addition, the calculation amount is very small, and real-time operations can be carried out on a mobile phone.

Description

technical field [0001] The invention relates to the technical field of camera calibration, in particular to a system and method for fast and automatic positioning of color block areas of 24-color color cards. Background technique [0002] When adjusting the white balance and color balance of the camera module, it is first necessary to take a photo of the 24-color color card, and then compare it with the photo taken by the target camera. During the comparison, it is necessary to manually select the color patch area to be compared on the interface, and then program to extract and compare. This kind of manual operation interface selects the color block area that needs to be compared, which makes the operation more cumbersome and seriously wastes manpower and time. Contents of the invention [0003] The present invention provides a system and method for fast and automatic positioning of color block areas of a 24-color color card to solve the technical problem of a serious was...
