Progress Report

Our 3D model centers around Shibuya station, and spreads to capture a wide area of 800 meters by 500 meters.
We began arranging the photographs by looking at which areas had the most information and detail. Large amounts of detail helped to create the most accurate 3D viewpoint possible.
Based on these models, the streets of Shibuya in 1964 will be reproduced in three dimensions.

We used photogrammetry to derive the unevenness of the city from aerial photographs of Shibuya in the 1960s. This method analyzed parallax information, shadows, and contrast of the photographs to create a 3D solid.
Through this method, we can grasp the relationship of the height of each building, and use it as a guide for detailed model creation.

Primarily around Shibuya station, we created a 3D model of the historical city buildings, lights and trees, using a texture projection method.
In this method, three-dimensional space is reproduced from the photograph by specifying the shooting location of the provided 1960's photo, and mapping it as the texture of the 3D model.
