激光扫描显示图像转换坐标变换时序变换 laser scanning display image conversion coordinate transformation timing transformation Lissajous Lissajous

摘要

在激光扫描显示技术中，基于Lissajous图形的扫描显示具有扫描路径不规则的特点。为了使常见的逐行光栅扫描图像输入经过Lissajous扫描后正确输出显示，需要进行图像转换。按照一定的像素坐标和像素时序解算方法，计算出Lissajous扫描轨迹中当前显示像素与下一显示像素的坐标和时序关系，并参照解算出的扫描坐标和时序，提取原输入图像对应坐标处的像素进行输出，从而完成一幅图像的Lissajous扫描显示。利用Matlab对880*660@25 Hz分辨率图像进行仿真分析，得出了Lissajous扫描显示的图像像素坐标数据和时序数据，并统计出了两种数据的分布情况，仿真结果表明，该图像显示算法能准确有效地完成光栅扫描图像到Lissajous扫描的显示转换。

Abstract

In the laser scanning display technology,the displayed images based on Lissajous graphic have an irregular scan path.In order to correctly display the input common progressive raster image by Lissajous scanning,it needs image conversion.According to a certain method for calculating the pixel coordinates and pixel timing,the relationship of timing and coordinates between the current display pixel and the next pixel can be calculated out.Then,the corresponding coordinate pixel value can be extracted from the input image to complete an image of Lissajous scan display.Simulation was made to images of 880*660@25Hz by using Matlab,and the pixel coordinates and timing data of Lissajous scanning display were obtained.Statistics was made to the distribution of those data.The simulation results show that the algorithm can convert the input image to Lissajous scanning effectively.
