Abstract:
The present invention discloses a noise processing method and apparatus. The method includes: selecting a pixel in an area array, which is formed by arranging a plurality of pixels in a matrix; obtaining pre-stored depth information corresponding to the pixel; performing pixel dispersion calculation according to the depth information corresponding to the pixel, to obtain at least one dispersion of the pixel, the dispersion being used to indicate a degree of dispersion between the pixel and another pixel in the area array; and identifying the pixel as a noise and removing the pixel from the area array when the at least one dispersion of the pixel is greater than a preset threshold. According to the above method, the dispersion between the pixel and the another pixel in the area array is calculated according to the depth information corresponding to the pixel, and the pixel is identified as a noise and is removed from the area array when the at least one dispersion of the pixel is greater than the preset threshold. Therefore, noises in the area array may be identified and removed, which resolves a technical problem that generated noises may affect accuracy of the depth information.
