Abstract

A registration and fusion method for the high-frame-frequency images of multi-load photoelectric tracking measuring equipment is disclosed, which belongs to a registration and fusion method for high-frame-frequency visible light and infrared images in the technical field of photoelectric tracking measurement. The to-be-solved technical problem is to provide a method for realizing registration andfusion for the high-frame-frequency visible light and infrared images of multi-load photoelectric tracking measuring equipment. The technical scheme for solution is as follows: a common-path design of visible light and infrared light is utilized, and the subsystem of the adjusted equipment is started; a visible light sensor and an infrared light sensor observe a target simultaneously; one star point is formed on a monitor and three star points are recorded; the translation quantity, the rotation quantity and the zooming quantity between the two sensors are calculated; the images are registered after calibration; and then the visible light image and the infrared image are processed by histogram specification method and window function method, so as to obtain the optimal fusion effect. The method is simple, easy in realization, low in cost, and capable of satisfying registration and fusion with high real-time performance for visible light and infrared images.

[0002] In order to realize the test of aircraft flight calibration, stealth performance, etc., and the observation of key stages such as missile departure from beam, descent and flight attitude, a multi-load photoelectric tracking measurement system was established, in which high frame rate visible light and infrared heterogeneous image registration And fusion becomes the key, not only requires strict registration of visible light and infrared images, but also high-quality fusion, more importantly, to meet the requirements of high real-time performance (100 frames per second), the current image registration algorithm is not very good Completing the registration of visible light and infrared heterogeneous images requires a lot of computing time. Fast image fusion algorithms in the time domain such as weighted average, maximum gray value, and minimum gray value cannot eliminate the edge traces of the fused image. Wavelet Algorithms with good fusion effects in the frequency domain such as transform and contourlet transform cannot meet the real-time requirements
