Embodiment Construction

[0019] The present invention will be described in detail below based on the drawings and embodiments, but the protection scope of the present invention is not limited thereto.

[0020] The image streaking algorithm designed in the present invention is aimed at high-speed impulse image sensors. It is necessary to determine the light intensity of the "background" and "object" parts in the application. Because of the problems that may exist in actual use such as rapid changes in brightness and uneven illumination, you can choose the average value of the trigger interval in a small area that is even and smooth. In the actual collected video data, the threshold can be set T =2, for a certain trigger interval of a pixel, record the average value of the first 3 pulse intervals as m 1 , The average value of the last 3 pulse intervals is m 2 , If the variances before and after are both less than T , And the interval length is between m 1 with m 2 Between, the interval is judged to be the ...

Abstract

The invention discloses a reconstructed image trailing elimination algorithm applied to a high-speed pulse sensor. By identifying an trailing interval and calculating the proportions of two brightnessobjects causing trailing in the same triggering interval according to the mechanism of triggering and recovering the image gray scale of the pulse type high-speed camera, the boundary of the object in the trailing interval is recovered, trailing can be eliminated in the high-speed camera reconstructed video, and the quality of the reconstructed image is improved.

Description

Technical field [0001] The present invention relates to the field of image processing algorithms, in particular to an algorithm for removing tailing of reconstructed images applied to high-speed pulse sensors. Background technique [0002] High-speed cameras can complete rapid and multiple sampling of high-speed targets in a short time. It has outstanding advantages such as real-time target capture, fast image recording, instant playback, and intuitive and clear images. It is widely used in military industry, scientific research experiments, aerospace, Industrial production, film and television advertising, sports competition, mass life, etc. High-speed cameras can be used not only for image recording, but also for traditional measurement of displacement, velocity, acceleration, etc., production process inspection and quality control. Driven by the needs of various industries, people’s requirements for the performance of high-speed cameras continue to increase. As the frame rate...
