| 摘 要： | 本文给出了一种线列阵CCD智能遥测系统.文中提出以线列阵CCD输出脉冲的包络线信号作为摄取目标的特征.对CCD产生的正弦型、高斯型、矩形型、脉冲型等几种输出包络信号进行了傅里叶频谱分析,在非图像显示的场合下,可较大地降低采样频率,提高实时性,用较少的数据量实现对目标的特征抽取、分析、识别等处理.

| Abstract: | This paper presents an intelligent telemetry system using linear array CCD. It is proposed that envelope signals formed by the CCD output pulse series wave serve as the feature of the photogrammetry target. A comparison of the results of a Fourier frequency spectrum analysis for CCD output enveloping curves such as the sine wave, Gaussian wave, rectangular wave and pulse wave makes it possible to conclude that after this kind of method is used in telemetry application in the case of non-image display, the sampling frequency to the envelope signals will be lower, the efficiency will be improved and the resource extravagance will be cut down. By combining computer processing techniques with pattern recognition methods, the extraction, analysis, judgement and recognition of the target features are possible with a smaller amount of data. |
