摘　　要：在多视点自由立体显示中,针对柱透镜光栅参数与显示器像素不匹配造成的串扰问题,提出利用图像插值的合成方法对图像进行缩放处理。以9视点为例,提出缩放比例系数k,实现双线性插值算法的改进。嵌入式样机测试结果表明,该方法能够满足显示器像素宽度与柱透镜参数的完全匹配,串扰度从13.55%降低到1.40%,降低了12.15%,图像分辨率明显提高,立体显示效果更好。In order to solve the problem of crosstalk caused by the mismatch between lenticular lens parameters and monitor pixel in multi-view 3D autostereoscopic display,a new method that could scale the three-dimensional composite image using image interpolation was presented. Taking the 9viewpoint as an example,the scaling factor k was proposed,by which the bilinear interpolating scaling was improved. Embedded prototype test results show that the better match between lenticular lens parameters and monitor pixel leads to the better display effect. The crosstalk is reduced from13. 55% to 1. 40% and the image resolution is improved effectively.
