靶场光测数字图像无损压缩技术方案设计

为了解决困扰靶场的海量光学测量图像信息存储和传输问题,在满足光测数据处理精度前提下实现较高的压缩比,根据靶场光测数字图像特点,采用H.264的编码方案对目标区域和背景区域进行编码,得到了70倍压缩图像数据和压缩前后目标在图像坐标系中的坐标结果。结果表明,光测数字图像无损压缩技术实现了背景区域的高倍压缩和对目标区域的无损压缩,从而既满足了靶场数据处理精度需求又大大减少了测量图像信息量,该技术可对标准位图图像进行处理,符合国内各靶场的测量图像标准,可在其它靶场广泛推广。

Project design for optical image lossless compression technique in range

In order to obtain maximum compression ratio and solve the problem of tremendous information transmission and storage under the condition that the images meet the requirement of data processing precision,according to the character of digital image,H.264 was applied to encode object region and background region encoding respectively so that 70 multiple compression picture data and object coordinates in the image coordinate system were obtained.The experimental results illustrated that the object region lossl...
