The invention provides a photographic device and method for license plates of moving vehicle. The photographic device comprises a multi-type sensor and a camera, wherein the camera is integrated with a preset port; and the multi-type sensor is connected with the camera through the port, collects an external sensing analog signal, and inputs the signal to the camera in real time. The camera comprises: a shooting module, which is used for shooting and storing real-time vehicle video information; a first processing module, which has at least one preset threshold value and is used for carrying out conversion processing on the sensing analog signal, judging whether the processed sensing analog signal reaches an alarm threshold value or not according to the preset threshold value, and generating a trigger instruction if the processed sensing analog signal reaches the alarm threshold value; and a license plate extraction module, which is used for extracting license plate information according to the trigger instruction. The multi-type sensor is connected through the preset port of the camera to complete recognition and acquisition of the license plate information in the vehicle video information in a target area, so the multi-type sensor and the license plate camera can be highly integrated, fused and linked, and the hardware pressure of the license plate camera is greatly reduced.

    本发明提供一种移动车辆车牌摄像装置及方法,包括:摄像机集成有预设的端口,多类型传感器通过端口连接摄像机,采集外部的传感模拟信号实时输入至摄像机;摄像机包括:拍摄模块用于拍摄实时车辆视频信息并存储;第一处理模块预设有至少一个阈值,用于对传感模拟信号转换处理,并根据预设的阈值判断处理后的传感模拟信号是否达到报警阈值,若达到报警阈值则生成触发指令;车牌提取模块用于根据触发指令提取车牌信息。通过将多类型传感器通过摄像机预设的端口连接,完成对目标区域内车辆视频信息中的车牌信息的识别与获取,使得多类型传感器与车牌摄像机能够高度集成、融合与联动,大大降低车牌摄像机硬件的压力。
