摘要
根据视频图像电子叠加原理,对视频电子分划瞄准具进行了设计,完成"屏幕存储映射"方式的电子分划线及操作提示符场叠加。利用可编程逻辑器件和单一 OSDC 芯片的模拟视频分划线叠加设计进行总结,提出 DV 格式数字叠加处理方案。由于瞄具电子分划需要根据目标位置进行手动定位,所以重点对每种方案的分划线叠加位置和移位精度进行分析。利用其中的 OSDC 芯片叠加方案制成小型红外电子分划枪瞄具整机,有望利用数字视频叠加技术进行单兵武器数字化系统的全面研制。
Based on principle of image compound,the electronic aimed-instrument is designed using the 'screen storage mapping' method,so that electronic aim-line and prompts were compounded simultaneously in one field. Utilizing the way of CPLD or OSDC design in the AV format,aim-line commixed with scene image is proposed under the DV format.Electronic aim-line needs remotion to get the track of target,so precision of compound position and shift are analyzed to each design.The sample machine of infrared aimed-instrument with electronic collimation is made,which is used the method of OSDC chip in video compound,and it was small and portable.The system of signal-soldier digital weapon using the DV format compound technique will have been developed.
