摘　　要：为实现全景视频技术在工程机械设备中的应用,针对传统全景视频拼接技术存在一定的失真性,同时拼接过程相机畸变矫正时间长,缺乏实时性,以及图像产生拖影等问题,提出一种优化图像畸变和提高图像拼接速度的全景拼接融合算法。该算法利用离散余弦变换进行高频系数滤除,有效提高了全景拼接图像的质量并缩短了拼接用时。实际应用结果表明,采用该技术可将拼接用时减少45%。In order to realize the application of panoramic video technology in engineering equipment,in view of certain distortion of traditional panoramic video stitching technology and the problems of long camera distortion correction time,lack of realtime performance and image smear during the stitching process,a panoramic stitching fusion algorithm to optimize the image distortion and improve the image stitching speed is proposed,which uses discrete cosine transform to filter out high-frequency coefficients,effectively improving the quality of panoramic stitching images and shortening the stitching time.The practical application results show that the stitching time can be reduced by 45%with this technique.
