Topcon Road Condition Evaluation System Measures Distance, Height and Area

Topcon Road Condition Evaluation System Measures Distance, Height and Area

Topcon showed a road condition evaluation system that uses video shot by a 360° camera at the 3D & Virtual Reality Exhibition.

“The IP-S2 Lite system consists of a combination of a 360° camera, an inclinometer and a GPS, but the type shown here also has a laser scanner attached to it. The IP-S2 Lite creates a video using the 360° camera, taking 16 shots per second and extracting the characteristics of each, one by one. Then by linking the characteristics of the 16 frames per second, the system can make a 3D video from the position of the camera and the surrounding 360° video.”

The GIS position information and video are linked based on the characteristics that were extracted, and it is possible to measure the distance, height and surface in 3D from the video data that was shot. CG objects can therefore also be positioned in the actual moving frames that are shot. In a project in April this year the Geospatial Information Authority used IP-S2/Lite to photograph and measure the condition of areas damaged in the earthquake.

“Measurements were made along the coastline of Miyagi Prefecture from mid-April, and in May measurements were made from as far north as Kuji in Iwate Prefecture, down to near Ishinomaki in Miyagi Prefecture. I think in the future this kind of video will be used to update maps of inland areas as well, not just the coastline. Once this kind of data is taken, updating becomes necessary, and in this case they did not have data from before the earthquake, but now they have run it and have post-earthquake data, so it should be helpful in the recovery, and may be used in the updating work.”
