Problems solved by technology

If the SDI video stream is used to transmit images, the frame rate of SDI is 25 frames / s. Under the existing bandwidth, it is necessary to perform lossy compression on the image with a high compression rate, which will cause the target in the image of the command center to be lost, causing the aircraft to influence of status

Embodiment Construction

[0018] The processing and displaying of the image data in the present invention comprises the following steps:

[0019] Step 1, determine the wave gate area

[0020] The optical picture has a black sky as the background, and the spacecraft is the target in the image. The different gray values ​​on the picture indicate the dimness of the target, and the target will be surrounded by a white rectangular frame. Starting from the upper left corner of the image, scan the pixels from left to right and from top to bottom to find a side of the white rectangle, and then find the target rectangle according to the position of the calculated side. The area surrounded by the rectangle is is the wave gate area. Similarly, start from the upper right corner of the image, scan from right to left, top to bottom, or start from the lower left corner of the image, scan from left to right, bottom to top, or start from the lower right corner of the image, Scan from right to left and bottom to top; ...

Abstract

The invention discloses a fast image interpolation processing method based on wave gate detection, which detects wave gate areas in images captured by optical equipment, uses cubic cubic interpolation for effective target areas, and adopts bilinear interpolation algorithms for other areas. The invention improves the real-time performance of the algorithm, avoids the distortion when the image is scaled as far as possible, maintains the sharpness of the target in the image, and eliminates the phenomenon of target fading and wave gate target frame loss caused by the ordinary scaling and sampling process, so that it can be timely The commander provides visual image information.

Description

technical field [0001] The invention relates to the field of image display processing, in particular to a fast image interpolation processing method for processing and displaying multi-channel optical continuous measurement pictures. The tracking images of the spacecraft by optical equipment are recorded in real-time to files in the form of multiple frames per second, and are continuously transmitted to the monitoring center for processing and display. The invention proposes a fast image interpolation processing method based on wave gate detection, detects the wave gate target area in the image, uses cubic cubic interpolation for the target area, and adopts bilinear interpolation algorithm for the remaining areas, which has better quasi-real-time performance and adapts to The display requirements of different resolutions avoid the phenomenon of edge loss in the display of the target frame in the optical image. Background technique [0002] In the process of space launch tra...
