Embodiment Construction
[0023] Such as figure 1 As shown, the practical shooting device of the present invention includes a color camera (generally an industrial camera), an RWB three-color light source (the RWB three-color light source has red (R), white (W) and blue (B) three-color light There are no special requirements for the composed light source, for example, a ring light source arranged in R, W, B from top to bottom, or a flat light source arranged in B, W, R from outside to inside), one for controlling RWB Light source control system for three-color light sources.
[0024] Place the object to be photographed on the shooting platform, control the RWB three-color light source to emit background light in the light source control system, and take images of the object to be photographed by the color camera.
[0025] combine figure 2 As shown, the present invention includes the following implementation steps in order to obtain images with more obvious layering and optimize image quality:

The invention discloses a device and a method for shooting a color image based on red, white and blue (RWB) three-color light. The method comprises the following steps of: shooting the same position of the same object under RB two-color light and W light by using the same color camera to obtain a first image and a second image respectively; and synthesizing the first and second images by using point-by-point computation to obtain a synthetic image. According to the device and the method, the same zone position is shot twice according to the principle of interference of the RWB three-color light, the shot images are synthesized into a target color image, the interference of red, green and blue (RGB) light in the synthetic image is low, and the synthetic image is remarkably layered, so that the quality of the image is optimized.
Description
technical field [0001] The present invention relates to image processing technology, in particular to a device and method for shooting color images for reducing mutual interference between RGB colors. Background technique [0002] RGB is the color mode of color light, R stands for red, G stands for green, and B stands for blue. Because each of the three colors has 256 brightness levels, the superposition of the three colors can form 16.7 million colors (commonly known as "true color"). [0003] The RGB mode is also called the additive color mode because the three colors of red, green and blue are superimposed to form other colors. In this color mode, each primary color will form a separate color channel (Channel), and the brightness of the color on each channel is 256 steps, ranging from 0-255. Then the three monochrome channels are combined into a composite channel, the RGB channel. Therefore, the color of each part of the image is determined by the values on the three...
