Zusammenfassung:The invention provides a resolution test method, device and system for iris acquisition equipment. The method comprises the following steps: receiving an image of an equipment resolution test card acquired by iris acquisition equipment to be tested; and detecting preset marks in the image, detecting preset mark outer frames when the number of the detected preset marks meets a preset requirement, determining a measurement area based on a detection result of the outer frames, and calculating the resolution of the iris acquisition equipment to be tested through the measurement area. According tothe scheme, manual marking of a test area in a traditional method is avoided, subjective influences are eliminated, and a stable reproducible test result can be obtained. 本发明提供一种虹膜采集设备的分辨力测试方法、装置及系统,该方法包括:接收待测虹膜采集设备采集到的设备分辨力测试卡的图像;检测所述图像中的预设标记,当检测到的预设标记数量符合预设要求时,检测预设标记外框,基于对外框的检测结果确定测量区域,通过测量区域计算待测虹膜采集设备的分辨力。该方案避开传统方法中人工标记测试区域,排除主观影响,能够取得稳定可复现的测试结果。
