The present invention relates to a finger vein detection system and, on the other hand, to a system for determining whether it is suitable for driving. The invention relates to a method for judging whether to drink by finger vein information, which comprises the following steps of: pre-collecting and storing the finger vein information of the public, simultaneously collecting the finger vein information and the stored information during detection, comparing the finger vein information with the stored information, evaluating to obtain an evaluation value, weighting the evaluation value to obtain a final value P, and judging that a driver has drunk if the final value exceeds a certain threshold value. The finger vein information comprises a finger vein blood vessel diameter, a finger vein blood instantaneous flow velocity and a finger vein blood reflection infrared spectrum. The method can be applied to drunk driving limitation. The existing finger vein detector only needs to be properly modified to quickly judge, and the system prohibits the vehicle from starting, so that the safety is guaranteed.
本发明涉及一种指静脉检测系统,另一方面,涉及判断是否适合驾驶的系统。一种指静脉信息判断是否饮酒的方法,它包括预先采集公众的指静脉信息并保存,检测时同时采集这些指静脉信息和保存着的信息进行比对进行评估得到评测值,评测值经过加权处理的到最终值P,最终值超过一定阈值则判定饮酒了,指静脉信息包括指静脉血管直径,指静脉血液瞬时流速和指静脉血液反射红外光图谱。本发明能应用在限制酒驾中。只需适当改造现有指静脉探测器,即可用来快速判断,并让系统禁止车辆启动,保障安全。
