摘　　要：为了提高无线三维扫描仪的图像传输帧率,提出一种结合有损图像编码、无损图像编码以及并行化方法的高性能图像压缩算法。基本思想是根据设置的门限值通过并行化方法查找替代值个数,然后根据替代值个数自适应选择有损图像编码或无损图像编码。实验结果表明,与多种常用的图像压缩算法相比,该算法不仅提高了图像的传输帧率以及重构图像的质量,还缩短了编解码耗时。To improve the image transmission frame rate of wireless 3D scanners,the paper proposes the high-performance image compression algorithm combining lossy image encoding,lossless image encoding,and parallelization method.The basic idea is to find the number of replacement values through a parallel method according to the set threshold value,and to select lossy or lossless image encoding adaptively based on the number of replacement values.Experimental results demonstrates that the proposed algorithm could not only improve the image transmission frame rate and the quality of reconstructed image,but also reduce the encoding and decoding time compared with various common image compression algorithms.
