Developmental Research on Automatization of Detection and Data-processing for Video Information in Crop Science

视频处理系统由电视摄像机、视频信号接口和微机组成，为农作物科学测量的自动化提供了保证。利用该方法可以进行植物的不破裂试验。2台电视摄像机支持三维测量。1.编制了系统控制和视频处理的计算机程序。分析了各种视频处理方法对作物科学信息的适应性。2.利用所提出的几何算法，可以在不同的视频火焰中指定叶片边缘上的特定点。3.当叶片轮廓绕其轴杆旋转时，叶片轮廓的分形维数不变。定义了通过计算分形维数，可以从几个不同形状的叶片中确定出进行定向调整运动的特定叶片。4.将该系统应用于葡萄叶面积季节变化的研究。5.该系统的开发取得了令人满意的结果，为进一步开展葡萄叶片定向运动的研究奠定了基础。

The video processing system was composed from TV-camera, video signal interface and micro computer, and provided for the automatization of crop scientific measurement. Non-breaking test of plants is enable by using this method. 3 dimensional measurement is supported by 2 TV-camera. 1. Computer programs were composed for the control of system and video processing. Various kinds of video processing methods were considered on their adaptabilities to crop scientific information. 2. The particular point on the edge of leaf can be specified in different video flame by using geometrical algorithm developed. 3. When leaf profile is rotated around its axle stem, the fractal dimension of leaf profile does not change. it was defined that the particular leaf of kudzu-vine on orientation-adjusting movenment can be specified among several different shaped leaves by calculating fractal dimension. 4. The composed system was applied to the study on seasonal changes of kudzu-vine leaf area. 5. The new research project on leaf orientation-adjusting movement of kudzu-vine is under planing by the satisfactory results of developed system.
