The invention discloses a multi-camera synchronous control device, which belongs to the technical field of machine visual sense. The multi-camera synchronous control device comprises a processing module, an encoder signal input module, a triggering module, a parameter signal input module, and a synchronous control module. The encoder signal input module is connected to the processing module and isused for sending coding signals generated by the encoder to the processing module; the triggering module is connected to the processing module and is used for sending triggering signals to the processing module; the parameter signal input module is connected to the processing module and is used for sending device parameter setting signals to the processing module; the synchronous control module is connected to the processing module and is used for outputting synchronous control signals generated by the processing module to each camera. Consequently, the synchronous control of various camerascan be realized, and the line frequency of a line-scan camera can be adjusted through revising parameter setting signals.
Description
technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a multi-camera synchronous control device. Background technique [0002] In the online inspection of printed matter surface quality, for large-format printed matter, the field of view of a single camera cannot cover the entire inspection area, and multiple cameras need to be used for image stitching to complete the visual inspection of the surface quality of the entire large-format printed matter. In the printing process, multiple cameras are required to collect images at the same time, and then complete the quality inspection task through image stitching and algorithm processing. Otherwise, the time when each camera takes pictures is inconsistent, and the collected images are images in different states of printed matter, which will bring difficulties to image stitching and detection algorithms. [0003] At present, line scan cameras are mostly used for surfac...
