The invention relates to an automobile whistling snapshot device on-site calibration system based on dynamic characteristics. The automobile whistling snapshot device on-site calibration system comprises an automobile whistling snapshot device, a sound source, an intelligent trolley, a binocular lens, a signal generation device, a signal acquisition and output device, a GPS synchronous clock and acomputer. The automobile whistling snapshot device is installed on a supporting rod. The binocular lenses are arranged at the left side and the right side of the sound source and are used for measuring the physical space position relation between the sound source and the whistling snapshot device. The signal generating device is connected with the sound source and is used for driving the sound source; the intelligent trolley is in wireless connection with the computer, the intelligent trolley serves as a sound source carrier, and the actual position of the sound source is controlled and output in real time; and the GPS synchronous clock is respectively connected with the signal generation device and the signal acquisition and output device, and is used for synchronizing the sound production time of the sound source and the snapshot completion time of the whistling snapshot device.
本发明涉及一种基于动态特性的汽车鸣笛抓拍装置现场校准系统,包括汽车鸣笛抓拍装置、声源、智能小车、双目镜头、信号发生装置、信号采集与输出装置、GPS同步时钟和计算机。所述汽车鸣笛抓拍装置安装于支撑杆上;双目镜头置于声源的左右两边,用于测出声源与鸣笛抓拍装置的物理空间位置关系;信号发生装置与声源相连,用于驱动声源;智能小车与计算机无线连接,以智能小车作为声源载体,实时控制并输出声源实际位置;GPS同步时钟分别与信号发生装置信号、信号采集与输出装置相连,用于同步声源发声时间以及鸣笛抓拍装置完成抓拍的时间。
