PURPOSE:To generate the scenery picture of woods having reality by extracting the area of the woods and an wood parameter by executing the picture processing on an aerial photograph, generating the three-dimensional form of each tree by using a method such as grow-up simulation, etc., and generating the picture based on the three-dimensional form. CONSTITUTION:The two-dimensional wood area in the aerial photograph is calculated and transmitted to a grow-up simulator 3 by a picture processor #1 and the local wood parameter is calculated over the whole area of the aerial photograph by a picture processor #2. The grow-up simulator 3 calculates the three-dimensional wood area based on three-dimensional geographical data and wood area, and executes grow-up simulation based on the wood parameter. Then, the three-dimensional model of the plural trees is generated. A picture generator 4 executes the picture generation processing of the three-dimensional geographical data and the three-dimensional model of the trees, and outputs the picture. Thus, the scenery picture, in which each tree has the reality, can be generated. |
