Abstract

The invention provides a combined bioassay system for iris and cortical tissue. The system comprises an optical imaging device, biological tissue activity detection analysis and an image analysis-based measurement method. The bioassay system is suitable for all users, has adaptability to normal people and meets the requirement of national level-based large-scale application; the most reliable biologic tissue activity detection analysis ensures the reliability of the bioassay system per se; and the image analysis-based measurement method improves the accuracy and the reliability of the performance of the bioassay system.

Description

[0001] This application is a divisional application document of patent: 200710156256.1, the original application date: October 15, 2007, and the original invention name: biometric system combining iris and cortical tissue. technical field [0002] 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 [0003] 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: [0004] 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 ...
