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

该视频处理系统由摄像机、视频信号接口和微型计算机组成，实现了农作物科学检测的自动化。利用该方法可以实现对植物的不间断试验。3维测量由2个电视摄像头支持。1.编制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确定叶片边缘的特定点。3.叶型绕轴茎旋转时，叶型的分维不变。通过计算分维，定义了葛根定向器运动的特定叶片可以在几个不同形状的叶片之间进行区分。4.将合成系统应用于葛根叶面积季节变化的研究。5.葛根叶向调整运动的新研究项目正在筹划中，开发的系统取得了令人满意的结果。

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.
