Study of Construction of Image Data-Base System about Plant Growth with Three Dimensional Color Image Processing

1994年，完成了三维彩色图像处理系统构建的基础实验。菠菜是实验的样本，它的观点既在样本的上方，也在样本的侧面。使用两台3-CCD型电视摄像机和一台普通35mm摄像机拍摄这些图像。来自电视摄像机的图像数据被记录在录像带中。样品侧视图在水平面上从8个方向每45度测量一次。利用图像处理系统从实像中确定样品每片叶片的X、Y、Z轴三个直角坐标，并确定投影图像和实像的叶片形状值（叶片面积、叶片周长、叶片直径和长度、叶片总面积、复杂性等）。复杂性不随时间的变化而变化，在叶片的面积和周长上，投影图像与实际叶片尺寸的误差在5%以内。1995年，在最后一次实验的基础上，对倾斜样品上的图像进行了分析。用带幻灯片的照相机从倾斜的视点对植物进行了拍摄，并对这些照片进行了图像处理。分析的数据为叶片和全株的面积和周长。样本是每20个花椰菜和生菜，每3天拍摄一次照片。利用胶片扫描器将载玻片上的全彩色图像输入计算机，分析后的图像数据和原始彩色图像数据保存在磁光盘上。这些数据可以随时从MO盘中调取并进行分析，通过这些数据的积累将构建全彩色、三维图像数据库系统。

In 1994, the fundamental experiments for the construction of three dimensional color image processing system were done. Spinach was the sample of experiment and its view points were both just above the sample and the side of sample. Two 3-CCD type TV cameras and a ordinary 35mm camera were used for taking these images. The image data from the TV cameras were recorded in video tape. The side view of sample was measured from 8 directions in horizontal plane every 45 degrees. Three rectangular coordinates of X,Y,Z axis of each leaf of sample were decided from the real image by using an image processing system, and some values about the shape of leaf (area of leaf, circumferential length of leaf, diameter and length of leaf, total leaf area, complexity, and etc.) were decided about a projective image and a real image. The complexity did not change according to the day passing, and about the area and the circumferential length of leaf, the error between the projection image and the real dimension of leaf was in 5%.In 1995, the images over the sample with an inclination were analyzed in addition to the last experiment. The plant was taken photographs by a camera with slide film from the view point with an inclination, and these photographs were analyzed by image processing. The analyzed data were the each area and circumferential length of leaf and whole plant. The sample were every 20 numbers of broccoli and lettuce, and taking photographs was done about every 3days. A film scanner was used to input full color images on the slide film to a computer, and analyzed image data and original color image data were saved on magnetic-optical (MO) disks. These data are able to recall for analyzing from MO disk in any time, and the full color, three dimensional image data-base system will be constructed by the accumulation of these data.
