Transformation and Composition of Field Pictures for Estimation of Plant Growth in Paddy Field
parallel projected image
It is important to agricultural production to estimate a growth state of rice in paddy field. The system that diagnoses the growth of rice by the image analysis is proposed. This system transforms bird’s-eye view images of paddy fields to top views of a parallel projection and analyzes them. Image analysis is performed for each image. Therefore, there is a possibility that we cannot diagnose all farms within a limited period in case a farm to diagnose is wide. Analytical time is shortened by composing plural plane views to one piece of image. In this paper, transformation and composition methods of field pictures are proposed. The angle of depression of the camera is automatically calculated from the field picture and the map, and the field images are transformed to a parallel projected image. Parallel projected field image of target area is made by transforming them to be suitable for the map, and composing it.
