弹着水柱实时测量处理机对航拍的高分辨率含弹水柱和靶船实景图象进行序列图象处理和识别,实时提取出弹着点和靶船信息,计算出弹着偏差,并按入水时间为序传输给地面指挥中心,以便仿真分析系统误差和打靶精度,评估打靶效果和火炮性能。其测量原理是,以统计法确定的图象灰度阈值将弹着点图象分割,采用添加高亮度标志线和长方形靶船坐标系的线性方式识别靶船,利用点相关法及区域像素门限和距离门限处理单帧图象以滤除浪花等伪目标。该处理机的单帧处理由4块DSP浮点芯片TMS320C31构成的单帧处理板并行完成,图象序列相关处理由DSP浮点芯片TMS320C30构成的处理板完成,系统控制及其接口由FPGA/CPLD可编程逻辑器件实现。
Aiming at the real-time image processing and identification of high-resolution aerial shot-bearing water column and the target ship real-time images, a real-time measuring and processing machine was used to carry out sequence image processing and identification of the aerial images. Sequence transmission to the ground command center, in order to simulate the analysis of system errors and accuracy of shooting, shooting performance and artillery performance assessment. The measurement principle is that the grayscale threshold of the image determined by the statistical method will be used to segment the bomb point image, the target vessel is identified by the linear manner of adding the high brightness marker line and the rectangular target ship coordinate system, the point correlation method, the regional pixel threshold and the distance Thresholding single frame images to filter out false targets such as waves. The processor single-frame processing by the four DSP floating-point chip TMS320C31 constitute a single-frame processing board parallel completion of the image sequence related processing by the DSP floating-point chip TMS320C30 constitute the processing board to complete the system control and its interface by the FPGA / CPLD Programmable logic device implementation.
