[Case Study] 3D Laser Scanning of Cultural Heritage Measurement at Fukuoka Castle Ruins
It is possible to measure from a distance without the risk of damage to the object due to contact, allowing for high-precision measurements in a short time.
【Example】 Location: Fukuoka Castle Ruins Area: Approximately 700 square meters Number of Measurements: 35 locations Measurement Time: Approximately 3 hours and 30 minutes Measurement Data Confirmation: Approximately 1 hour (Total: Approximately 4 hours and 30 minutes) 【Measurement Conditions】 ■ Measurements can be conducted outdoors and indoors ■ Due to equipment specifications, a temperature range of 5°C to 40°C is desirable during measurements ■ Measurements can be conducted at night or in dark places, but obtaining color information may be difficult ■ Outdoor measurements may be impossible depending on weather conditions due to laser reflection and refraction from rain or fog ■ Glossy surfaces that reflect lasers or black objects that absorb lasers will reduce point cloud acquisition rates * Mirrors and glass, for example, will almost not yield point clouds ■ Moving objects during measurement will be processed as noise during data processing * Considering the accuracy of point cloud acquisition, measurements during times when no people are present are preferable ■ Generally, measurements are taken from below, so point clouds of the top surfaces of objects cannot be obtained. If point cloud acquisition is necessary, measurements should be taken from a height 【Examples of Point Cloud Data Utilization】 ■ Dimension measurement ■ Cross-section display ■ Elevation display ■ Intensity display ■ 3D modeling ■ VR, etc.
