Online stevioside quality detection method and main control equipment

The invention discloses a stevioside quality on-line detection method and main control equipment, the stevioside quality on-line detection method comprises the following steps: pre-processing a stevioside image to obtain a pre-processed image, the pre-processed image comprising a stevioside area and a non-stevioside area; obtaining a target pixel point in the stevioside region, and obtaining a region of interest according to the relevance feature and the comprehensive relevance feature of the target pixel point; and correcting the pixel points in the region of interest to obtain a clustering region. According to the online detection method for the quality of the stevioside, disclosed by the embodiment of the invention, by acquiring the regularity of aggregation characteristic distribution of the pixel points in the region of interest and then correcting the pixel points in the region of interest, the interference of a granular part and noise of the stevioside can be avoided, so that the accurate agglomeration
