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

该视频处理系统由电视摄像机、视频信号接口和微机组成，为作物科学测量的自动化提供支持。该方法可实现植物的无损试验。2台电视摄像机支持三维测量。1. 编写了系统控制和视频处理的计算机程序。考虑了各种视频处理方法对作物科学信息的适应性。2. 利用所开发的几何算法，可以在不同的视频火焰中指定叶子边缘的特定点。3. 当叶片绕轴柄旋转时，叶片的分形维数不发生变化。通过分形维数的计算，确定了葛藤定向运动的特定叶片可以在多个不同形状的叶片中指定。4. 将该组合系统应用于葛藤叶面积的季节变化研究。5. 葛藤叶片定向调节运动的新研究项目正在规划中，已开发的系统取得了满意的结果。

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.
