Description
Technical Field
The invention relates to a video superposition technology, in particular to an optical axis consistency adjusting device.
Background
In the development process of the photoelectric system, various evaluations and test tests on the internal performance of a physical prototype of a photoelectric detection product are often required. In the photoelectric equipment, the infrared thermal imager and the visual field center of the television assembly (or physical optics) and the laser emission axis and the laser receiving axis must be calibrated, namely, three axes are parallel and consistent, and in addition, the consistency of the optical axes must be ensured when the television assembly and the infrared thermal imager are adjusted in long and short focuses. All the optical axes need to be accurately calibrated based on the scale marks in the visible windows, and the active equipment is realized by digitizing the video signals of the components and then realizing the treatment of cross superposition and the like through software on an upper computer. However, the original infrared and television images have no scale lines and center cross lines, and when the optical components are independently debugged in an internal field, the video processing system based on the industrial computer is not equipped, so that the debugging is extremely inconvenient. In the existing adjustment testing device, after the lens of the multichannel photoelectric system is repeatedly replaced, the consistency of the optical axis of the optical system needs to be readjusted, and the work is complicated.
