“…The resolution of the simulated camera is 2592*1944px, and the stripe enhancement process is shown in Figure 6. In order to verify the effectiveness of the algorithm, the mean square error (MSE) and peak signal-to-noise ratio (PSNR) are combined to evaluate the structured light image enhancement method in this paper, and the enhancement method in literature [11] is reproduced for comparison. The results are shown in Table 1.…”

“…Literature [10] calculated the width of each cross-section of the stripe, and then used the second weighted gray barycentric method of adaptive width to find the center of the stripe, which made the algorithm adaptive, but the amount of calculation was too large. Literature [11] proposed a color structured light decoding algorithm based on color migration, which uses color migration to enhance and de-illuminate the captured structured light pattern, but it will cause a certain color distortion.…”

In order to improve the accuracy of structured light measurement, this paper proposes a color surface structured light three-dimensional reconstruction method based on DB sequence. In the encoding stage, according to the principle that the greater the Euclidean distance between two points in the RGB space model, the greater the color difference, the color of adjacent stripes in the stripe pattern is constrained; in the decoding stage, in order to eliminate the influence of ambient light on the edge color of the stripes, Based on the threshold method, an improved algorithm is proposed. First, the color of the main area of the stripe is corrected by setting the RGB three-channel threshold. For the point where noise is generated by the crosstalk on the stripe boundary, a single-channel threshold and the other two-channel color are proposed. The method of co-constraining the size of the components. The experimental results show that for the measurement of achromatic objects, this method has high measurement accuracy and can be used for actual measurement.
