Special transient optical signal location image process based on DSP

研究并设计瞬态光辐射信号定位图像处理。根据瞬态光辐射的成像特点,提出了一套可行的定位处理系统方案,利用阈值分割去除了背景和弱噪声,提高了系统处理速度,对由于光学系统产生的图像失真进行了畸变校正,提高了系统的精度;最后对目标像点进行重心坐标的提取。实验表明,该硬件图像处理方案具有很高的实时处理性和定位准确性,可以很好地满足系统要求。

A spacial transient optical signal location image process based on the high-speed Digital Signal Processor is designed. A term of location process system is introduced based on the imaging characteristics of spatial transient optical signal. For Improving processing speed , filtrating the background and weak noises by threshold segmentation, for improving system＇s accuracy, disposing the distortion and calculating the Centroid of target data at last. Experiment results show that processing speed and measurement accuracy of this method are high, and can satisfy the request of locating system.
