Abstract

The invention discloses a full-automatic blood smear morphological analysis system based on machine vision and relates to the technical field of medical instruments. The system comprises an optical system unit, an upper computer software processing unit and a lower computer hardware unit; the optical system unit comprises a biological microscopic imaging system and a CCD biological camera; the upper computer software processing unit comprises a user control interface module, a blood smear image processing module and an upper and lower computer communication module; the lower computer hardwareunit comprises a focusing motion module and an image acquisition motion module; automatic focusing is performed through the optical system unit; a blood smear digital image is collected; blood smear image features are recognized and processed through a machine learning algorithm of the upper computer software processing unit; different types of leukocytes are classified and counted; and a processing result is displayed the a graphical user interface; a monocular microscope is matched with a reflective light source, so that an optical structure is greatly simplified, and rapid imaging is realized. The full-automatic blood smear morphological analysis system is high in working efficiency, high in accuracy and high in automation level.

Description

technical field [0001] The invention relates to the technical field of intelligent medical equipment, in particular to the fields of mechanical structure and image processing. Background technique [0002] Blood cell analysis is one of the most important and popular clinical testing items, which plays an important role in the prevention, diagnosis, differential diagnosis and prognosis of many diseases. For routine blood tests, the more commonly used test method is the automatic blood cell analyzer. This test method has relatively high precision, simple operation, and fast response speed, so it is used more in clinical practice, but it is only carried out by relying on the automatic blood cell analyzer. The recognition accuracy of cell morphology is relatively low. Therefore, this test method can only be used as a preliminary screening method for morphology. For the abnormal samples screened by the automatic hematology analyzer, then use the microscope to review to obtain m...
