Abstract

The invention relates to a software and hardware synchronous control method in a high-speed video measurement system, which is characterized in that more than two high-speed cameras are simultaneously controlled by a main control computer and a synchronous trigger circuit to realize synchronous acquisition of sequence high-speed images, and the synchronous control method comprises the following steps of: 1) starting an acquisition process; 2) starting a storage process; and 3) stopping the acquisition process. Compared with the prior art, the split-type high-speed video measurement system solves the problem that output images cannot be synchronized due to the fact that a plurality of high-speed cameras of an existing split-type high-speed video measurement system work independently, and the accuracy of high-speed video measurement is improved.

Description

technical field [0001] The invention relates to a high-speed video measurement technology, in particular to a software and hardware synchronization control method in a high-speed video measurement system. Background technique [0002] High-speed video measurement technology has a wide range of needs and applications in aviation, aerospace, machinery, automobiles, ships and other industries. The high-speed video measurement system simultaneously collects high-speed image sequences of the measured object from different angles through multiple fixed-position cameras, and uses stereo measurement technology to analyze the three-dimensional coordinates of the same spatial point in multiple images. One of the keys is to simultaneously send image acquisition control signals to multiple high-speed video image acquisition devices through the control device, and the high-speed video image acquisition devices perform synchronous image acquisition after receiving the image acquisition sy...
