Embodiment 1
[0034] In this example, refer to Figure 5 , the data comparison process performed by the data comparison module includes the following steps.
[0035] Step 1: Perform gray scale conversion on the data picture in the first data block and the data picture in the second data block to obtain the gray scale image of the data picture in the first data block and the gray scale of the data picture in the second data block For example, the grayscale conversion step can be S201: obtain the red, green, and blue values of each pixel; S202: use the grayscale algorithm to calculate a grayscale value Gray; S203: replace the original red of the pixel with the grayscale , green, blue value, wherein a grayscale algorithm provided by this embodiment is the average algorithm: Gray = (red + green + blue) / 3, of course, those of ordinary skill in the art can also use other grayscale algorithms (based on human perception , desaturation, decomposition, single channel algorithm) to calculate the ...
Embodiment 2
[0040] In this embodiment, calculating the difference value between the grayscale image of the data picture in the first data block and the grayscale image of the data picture in the second data block in step 2 above includes the following steps. S21: Normalize the image size of the grayscale image of the data picture in the first data block and the grayscale image of the data picture in the second data block to obtain a preset size of the data picture in the first data block A grayscale image and a grayscale image of the data picture in the second data block with a preset size. S22: According to the grayscale image of the data picture in the first data block of the preset size and the gradient information of the grayscale image of the data picture in the second data block of the preset size, determine the data picture and the data picture in the first data block and Coarse disparity value for the data picture in the second data block. S23: If the coarse screening difference ...
