A method and system for parallel acquisition management and control based on multiple high-speed cameras

Abstract

The invention discloses a parallel acquisition management and control method and system based on multiple high-speed cameras. According to whether multiple cameras have the same shooting angle for the same scene, switch to a time synchronous acquisition mode or a time alternate acquisition mode. Synchronous correction, on the basis of the line delay of the pulse signal transmission between the first-level synchronous controller and each camera, the corresponding synchronous correction amount is added, so that the pulse signal sent by the first-level synchronous controller reaches each camera at the same time, realizing multi-angle Simultaneous shooting, in the time-alternating acquisition mode, the time-alternating correction is performed, and the corresponding alternate acquisition correction amount is added on the basis of the line delay of the pulse signal transmission between the first-level synchronization controller and each camera, so that the first-level synchronization The controller, the invention has the function of working mode switching, and realizes the high-precision synchronous shooting control of multi-angle shooting and the high sampling rate of shooting at the same angle.

Description

technical field [0001] The invention relates to the field of image acquisition, in particular to a method and system for parallel acquisition management and control based on multiple high-speed cameras. Background technique [0002] At present, with the rapid development and progress of science and technology, the convenience brought by data and information is ubiquitous, among which image data is widely used and the most intuitive, so the research on image data acquisition and transmission is getting more and more in-depth. In the field of image research, the research on the high-speed motion process of objects is a very important part. The application fields of high-speed photography are very extensive. High-speed cameras can completely record the transient Convert it into an image signal, and finally send it to a dedicated image processing system. [0003] In some special application environments, the use of a single high-speed camera cannot meet the requirements, and mu...

Problems solved by technology

[0003] In some special application environments, the use of a single high-speed camera cannot meet the requirements, and multiple high-speed cameras need to work at the same time, which requires synchronous shooting of multiple high-speed cameras when shooting is required. , its shooting mode is single, it is difficult to control the shooting mode of multiple cameras to meet the shooting of various usage scenarios
