LabVIEW and VDM Extract color and generate gray image

stay LabVIEW Using visual development module in （Vision Development Module）. How to convert a color image to a grayscale image ？

LabVIEW Color image data is represented as unsigned 32 An integer （U32） Array for storage . These color images can be red, green and blue （RGB） Or color brightness saturation （HSL） Format . You need to convert the color image to HSL Format , Then extract the luminance plane . The brightness plane is completely corresponding to the gray image , also , It is the only color plane that can provide accurate expression of gray image . How to use LabVIEW and VDM Extract color and generate gray image IMAQ： Color images to grayscale images contain reusable code to demonstrate this concept .

the second VI Demonstrates how to transform an image from a color （RGB） Convert to grayscale image .

This simple program converts color images to grayscale in two ways ：1） take RGB Image to HSL Image and extract the brightness plane 2） from RGB Extract the red plane from the image . The accompanying drawings may be saved and used to illustrate the VI The function of . The file path to save the image should be located in the “ File path ” Control .
