Abstract

The invention provides and realizes a bioassay system for combined iris and cortical tissues, which comprises an optical imaging device, detection and analysis of biological tissue activity, and an assay method based on image analysis. The bioassay system is suitable for all users, has the applicability of common population, and satisfies the scale application based on national level; the most reliable detection and analysis of the biological tissue activity ensure the self-reliability of the bioassay system; and the assay method based on image analysis improves the accuracy and reliability of the performance of the bioassay system.

Description

technical field [0001] The invention relates to a bioassay system, in particular to an optical imaging device used in a bioassay system combining iris and cortex tissue, a biotissue activity detection and analysis method and a method based on image analysis. Background technique [0002] According to the basic research of the inventor's early related iris biometric system, the results of the actual large sample population test reveal the following shortcomings that need to be improved: [0003] 1. Although the visible iris standard proposed by the inventor earlier is: ≥ 70% at the time of registration and ≥ 40% at the time of comparison. However, about 1%-0.5% of users, especially elderly users, have less than 30% of the visible iris analyzed and cannot improve; about 0.01%-0.001% of users are affected by various eye diseases such as Degenerative pathological effects cannot be used for iris biometrics, so there is a need for a better biometric system that is applicable to a...
