A method for color adjustment of an industrial camera

Abstract

The application discloses a color adjustment method for an industrial camera. The method includes: Step 1. Obtain the original RGB image data in the image to be processed in the industrial camera, calculate the product of the original RGB image data and the saturation adjustment matrix, and generate an overall saturation adjustment matrix. The saturation adjustment image, wherein the saturation adjustment matrix is ​​determined by the saturation parameter and the image color conversion matrix; step 2, select at least three reference colors in the hue circle, and determine the hue adjustment according to the reference color and the adjustment direction in the user preference setting step size and saturation adjustment step size, and sequentially perform color dimension adjustments of different dimensions on the overall saturation adjustment image to generate a color adjustment image. Through the technical solution in this application, the system resources consumed by the matrix conversion in the color adjustment process are reduced, the image processing speed is improved, the multiplication and addition operations in the image processing process are reduced, and the programmable gate of the industrial camera can Array implementation, reducing the cost of industrial cameras.

Description

Technical field [0001] The present application relates to the technical field of image processing, and in particular, it relates to an industrial camera color adjustment method. Background technique [0002] Due to the difference between the problems faced by visual detection, there is a significant difference in the algorithm of the human body, and the industrial camera needs to provide color adjustment, and the user is adjusted in accordance with its own needs. Color adjustment is currently divided into two: overall color adjustment and different dimensional color adjustment, where the overall color adjustment is to meet the adjustment of the user's overall saturation, different dimensions color adjustment is aimed at different cameras, environment and algorithms, can Select different colors to make separate colors and saturation adjustments. [0003] In Image Signal Processing, ISP, or different dimensional color adjustments, or different dimensional colors, such as figure 1 I...

Problems solved by technology

Taking the conversion to YUV space as an example, the process of color protection degree adjustment is as follows: transfer the RGB value of the image captured by the industrial camera to the YUV space, perform color adjustment in the YUV space, and then convert it to RGB after completion, and output the adjusted Image, in the process of color adjustment, involves a total of two data conversions, which consumes a lot of system resources and requires high data processing performance of the hardware in the process, which in turn increases the production cost of industrial cameras
