Outline of Final Research Achievements

We conducted a part of developing the new inspection method of port facility that combines shape measurement by ultrasonic and optical images. This research reconstructed a 3D underwater image with color by combining three dimensional shape information by ultrasonic and optical images. In addition, made an image mosaic for the quay apron section and examined the deformation detection method.
The results of this research can be expected to help develop the inspection method to accurately grasp the existing facility situation and also as an aid to the development of the underwater construction technology.
