The invention belongs to the technical field of alcohol detection, and provides a vehicle-mounted alcohol detection method and system. The method comprises the following steps: simultaneously triggering an air blowing pipe of an alcohol detection device to pop up based on an alcohol detection request of a person, and starting video recording by a first camera and a second camera; simultaneously triggering the air blowing pipe to retract into the shell and the first camera and the second camera to stop video recording on the basis of alcohol detection ending feedback of the personnel, and simultaneously acquiring alcohol detection data and video recording data of the first camera and the second camera; carrying out portrait extraction on the video data based on an image processing algorithm to confirm that a person requesting alcohol detection is consistent with a person who carries out alcohol detection, and when no person is replaced in the whole alcohol detection process, processing the alcohol detection data to obtain an alcohol detection result; when the alcohol detection result is confirmed to be correct, the ignition switch is triggered to be switched on. According to the invention, the hidden danger of cheating in the existing vehicle-mounted alcohol test is improved.

    本发明属于酒精检测技术领域,提供了一种车载式酒精检测方法及检测系统。所述方法包括:基于人员的酒精检测请求同时触发酒精检测装置吹气管弹出,以及第一摄像头和第二摄像头开启录像;基于人员的酒精检测结束反馈同时触发吹气管收回至所述壳体内,以及所述第一摄像头及所述第二摄像头停止录像,并同时获取酒精检测数据及第一摄像头及第二摄像头的录像数据;基于图像处理算法对所述录像数据进行人像提取以确认请求酒精检测的人员与进行酒精检测的人员一致,且在整个酒精检测过程中无人员更换时,对所述酒精检测数据进行处理以获取酒精检测结果;确认酒精检测结果无误时,触发点火开关接通。本发明改善了现有车载式酒测中的作弊隐患。
