Embodiment 1

[0021] like figure 1 As shown, the present invention is realized through the following techniques and calculation methods. Realize the automatic counting of the number of white blood cells in the blood microscopic image. At the beginning, the image acquisition interface (7) first obtains a blood cell image at the current observation position of the microscope and calculates the image information entropy, and controls the vertical direction through the position regulator drive interface (6). The focus position adjuster (2) moves one vertical step upward or downward along the longitudinal axis, and then collects an image and calculates the image information entropy, and selects the direction corresponding to the maximum value of the information entropy of the two images to advance one vertical step Then judge the size of the image information entropy at the location until the maximum image information entropy position is found. The ideal focus position is the maximum image infor...

Abstract

A method for automat calling counting white blood cell number in blood microscopic image includes adjusting longitudinal position to use image information entropy maximum position as longitudinal position of image collection, controlling horizontal x and y directional movement by utilizing position regulation to drive interface for finalizing counts of white blood cell in stained blood cell carrier plate.

Description

【Technical field】: [0001] The invention relates to the technical field of application of photoelectric image automatic identification and statistical methods, in particular to an automatic counting method for white blood cells in blood microscopic images. 【Background technique】: [0002] Photoelectric image recognition is the frontier content of intelligent instrument research and an important means of automatic detection technology. It involves the key content of computer software and hardware technology, image information processing technology, mechatronics technology and other emerging disciplines. Automatically counting the number of white blood cells in blood microscopic images can reduce the heavy labor caused by conventional manual counting methods and at the same time reduce human measurement errors, which is an urgent problem to be solved in medical clinical testing. 【Invention content】: [0003] The purpose of the present invention is to solve the problems of hea...
