Abstract

The invention discloses a medical slide identification and positioning method based on machine vision, a system and a device thereof, comprising: 1) photographing the slide, obtaining a target area image of the slide, and performing expansion and erosion operation on the target area image to smooth the image; 2) converting the image processed in the step 1) into a Mat type, and carrying out gray-scale conversion operation and thresholding operation on the Mat type image to obtain a clear target region image; 3) establishing pixel coordinates of the target area, drawing a minimum circumscribedrectangle and a center point of the target area image, and outputting the target image coordinates. The invention obtains the positioning coordinates of the slide through the image capturing picture processing of the slide, has the advantages of simple operation, high positioning accuracy, and can further cooperate with the four-axis manipulator to operate, thereby effectively avoiding the error caused by the irregular behavior of the operator in the operation process.

Description

technical field [0001] The present invention relates to the field of medical research image processing, in particular to a method, system and device for identifying and positioning medical slides based on machine vision. Background technique [0002] At present, in the medical field, there are a large number of operations on medical slides in various pathological researches and analyzes. Especially in the medical field, for some simple and repetitive operations that require high precision, manual processing has obvious disadvantages. In the field of medical research, the processing of cell slides is currently still in a manual state, and there will inevitably be some misoperations that will affect the accuracy. However, the use of mechanical devices to operate slides requires the ability to identify and position slides . Glass slides are generally rectangular, thicker, and have better light transmission. At present, there is no effective positioning and identification metho...
