Abstract

Embodiments of the present invention provide a multi-camera synchronization calibration method, device, and system. The device includes a processor, a synchronization trigger module, a digital tube timing module, and a storage module. Determine the synchronization signal sending time corresponding to each camera, and obtain the synchronization signal sending time set; the processor is further configured to send the first synchronization signal to the synchronization trigger module according to the synchronization signal sending time in the synchronization signal sending time set, and start the digital tube timing module Start timing, wherein the first synchronization signal is used to instruct the synchronization trigger module to send multiple pulse signals at different times obtained by the digital tube timing module, so as to realize that multiple cameras complete the shooting of photos at the same time. After the above solution is adopted, the delay error between cameras is reduced, and the synchronization between multiple cameras is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of camera calibration, and in particular, to a multi-camera synchronization calibration method, device, and system. Background technique [0002] With the development of science and technology, many application fields (such as in the field of aerial photogrammetry, vehicle mobile photogrammetry, and real-time monitoring of industrial automation production processes) will involve the use of multiple cameras to capture image data. [0003] When using multiple cameras to acquire image data, after each camera receives a pulse trigger signal, it will shoot according to the received pulse trigger signal. After the shooting is completed, multiple photos are obtained, and the obtained photos are respectively sent to the remote server for storage for subsequent use. And in the field of multi-camera applications, the synchronization requirements for photo shooting are relatively high, and genera...
