摘要
针对光电侦察设备手动操作、目视判读目标像高进行距离估算速度慢且准确度低等缺点,提出了基于图像判读的光电侦察设备快速测距方法。此方法在边缘增强、中值滤波等图像预处理之后,在跟踪目标的同时利用计算机自动读取目标像高进行距离估算。实验统计分析表明此方法大大缩短了距离估算操作时间,实现了跟踪目标像高的准确读取,从而提高了距离估算的准确度。
For electro-optical reconnaissance equipment, in order to solve the problem that the range estimation is slow and imprecise with manual operation which gets the target image height by visual interpretation to estimate the target range,fast ranging of electro-optical reconnaissance equipment based on image interpretation is proposed in this paper. The method obtains target image height by image enhancement and median filtering. Test shows this method which shortens the operation time greatly and reads target image height accurately improves the precision of range estimation.
