摘 要：由于硬件设备的限制，高动态范围图像（HDRI）需要由一系列同一角度，不同曝光量的图片合成得出。人工完成此过程需要较长时间，而较长的拍摄时间会提高后期处理时的工作量。为此，文章提出了一种以 Arduino 微控制器为核心，配合电机和个人电脑的自动化 HDRI 拍摄设备。该系统通过 Arduino、蓝牙、Wi-Fi、步进电机以及个人电脑的配合能够有效实现全自动完成 HDRI 全景图的拍摄，并能降低后续流程的工作量。

Abstract: Due to the limitation of hardware equipment, HDRI needs to be synthesized from a series of pictures with the same angle and different exposure. It takes a long time to complete this process manually, and the longer shooting time will increase the workload of postprocessing. Therefore, this paper proposes an automatic HDRI photographing device with Arduino microcontroller as the core, combined with motor and personal computer. Through the cooperation of Arduino, Bluetooth, Wi-Fi, stepping motor and personal computer, the system can effectively complete the shooting of HDRI panorama automatically and reduce the workload of subsequent processes.
