Image Grayscale Processing of Steel Tape Measure
The image acquisition system transmits the collected images of each whole meter of the steel tape to the upper computer, and the software in the upper computer processes each picture. The problem that needs to be solved in image processing is to use the correct method to detect the center position of the meter line of the standard and the measured steel tape, so that the measurement accuracy of the system can be guaranteed.
Image grayscale processing:
The collected images cannot be directly recognized by the recognition program, and grayscale preprocessing is required first. A grayscale image is a special color image with the same R, G, and B components. The variation range of one pixel is 255. Therefore, in digital image processing, in order to reduce the amount of calculation of subsequent images, Generally, images of various formats are first converted into grayscale images. The description of grayscale images, like color images, still reflects the distribution and characteristics of the overall and local chromaticity and brightness levels of the entire image. The grayscale processing of the image can be realized in two ways.
