Rice color sorting method based on improved center positioning method and HSV color model

The invention belongs to the technical field of agricultural product color sorting and grading, and particularly relates to a rice color sorting method based on an improved center positioning method and an HSV color model. The method comprises: shooting an image of rice on a conveyor belt; a full-color picture is recovered according to a delay RGB pixel selection algorithm, denoising operation is performed by using an image processing algorithm, and rice features are extracted to recognize different-color rice; the HSV color model can effectively distinguish color information of rice with different colors, and threshold parameters are dynamically adjusted according to actual color sorting requirements; the improved center positioning method can accurately position the pixel row where the rice center is located, and reliable coordinate information is provided for rice sorting. Starting from actual production and living needs, the cost is lower than that of other products aiming at a rice color sorting task, me
