Parallel processing method of electron racemization based on tidsp

Abstract

The invention relates to a TI DSP-based electronic derotation parallel processing method for an image rotation algorithm in an electronic derotation application. The invention optimizes the algorithm on the basis of TI DSP multi-channel parallel processing, overcomes the disadvantage of large calculation in the traditional derotation method, and realizes electronic derotation in real time. The invention improves the traditional rotation algorithm flow, that is, it is divided into three flow processes, and the three flow processes are processed in parallel, which is equivalent to only needing 1 / 3 of the original time to realize the rotation.

Description

Parallel Processing Method of Electron Racemization Based on TI DSP technical field The invention relates to a TI DSP-based electronic derotation parallel processing method for an image rotation algorithm in an electronic derotation application. Background technique In airborne optoelectronic equipment, electronic derotation technology can provide pilots with unrotated images, while traditional derotation algorithms have a large amount of calculation and are difficult to implement in embedded systems. The traditional rotation algorithm idea is as follows: The origin of the coordinate system in Figure 1 is selected at the center of the image, and the rotation is performed within a range of 360 degrees, with a minimum angle of 1 degree. Assuming that the coordinates before rotation are (x, y), the coordinates after rotation are (x1, y1), and the rotation angle is θ, then the rotation formula is derived as follows: According to formula 2, the coordinates (x, y) of the sou...
