Abstract

The invention belongs to the technical field of experiments and tests, and particularly relates to a real-time remote configurable image injection device with a plurality of output interfaces. According to the real-time remote configurable image injection device with the output interfaces, the time sequence needed by image output is controlled through connection of a programmable clock, an image distribution module and the output image interfaces are arranged, and remote real-time transmission is carried out through optical fibers. The real-time remote configurable image injection device with the output interfaces is provided with the output interfaces, the image output specification and the time sequence can be configured, and remote real-time image output is achieved.

Description

technical field [0001] The invention belongs to the technical field of testing and testing, and in particular relates to a real-time remote configurable multi-output interface image injection device. Background technique [0002] When debugging and testing the target optical search and tracking system, the simulated scene image generated by the scene generator is used as a signal source and injected into the system through the image input interface of the system for performance and function testing. This testing method is called injection testing. Injection testing requires an image injection interface device connected to the image input interface of the system under test. [0003] The current image injection devices are all implemented in the form of a computer plus a plug-in card. This type of device has a single image interface form, the output image format and timing are relatively fixed, and the distance between the computer and the device under test cannot be too far. ...
