Method, apparatus and system for inspecting cell crush

An apparatus for inspecting a cell crush, comprising:

• image acquisition circuitry configured to acquire images of a flowing cell assembly by an image acquisition device;
• feature extraction circuitry configured to extract image features from the images of the cell assembly;
• similarity matching circuitry configured to perform similarity matching between the image features and a preset crush model to obtain a similarity matching result, wherein
• the preset crush model corresponds to crush feature parameters comprising at least one of gray-scale value, shape, angle, length and width, and scaling, and
• the similarity matching circuitry is further configured to:
• identify, from the image features, similar crush feature parameters that are within different range values of crush feature parameters corresponding to the preset crush model;
• determine similar weights corresponding to the similar crush feature parameters based on the similar crush feature parameters;
• and
• obtain the similarity matching result based on the similar crush feature parameters and the determined similar weights;
• and
• inspection circuitry configured to obtain a cell crush inspection result based on the similarity matching result.
