摘要
针对机场跑道胶痕检测过程中,因数据量大而导致胶痕图像传输速率慢的问题,设计开发了基于JPEG图像压缩编码技术的机场跑道橡胶胶痕检测系统。该系统先后对机场跑道胶痕图像数据进行DCT变换、量化、编码,从而减小数据传输量,加快图像传输速率,提高系统的工作效率。通过仿真试验和实物测试,验证了JPEG压缩编码技术在胶胶痕检测系统中的可行性和有效性。
In order to solve the problem of low rate of images transmission in airport runway rubber glue mark detectionsystem due to large amount of data,we developed a JPEG image data compression encoded based airport runway rubberglue mark detection system. By combining DCT transform,quantization and encoding to compress the images,acceleratethe transmission rate and finally improve the efficiency of the system. By simulating and physical testing,the JPEGcompression encoding approach was proved to be feasible and effective in the rubber glue mark detection system.
