1P1-J07 Development of portable 3D measurement device which is available indoor and outdoor(3D Measurement/Sensor Fusion)

Abstract

We developed portable 3D measurement device. It is available where cars cannot run and GPS is not available. This device consists of camera, laser scanner and PC for data acquisition. Using this devise we propose a method combining camera data and scan data. First, the method calculates standardizes a self-position with Structure from Motion (SFM) and reflects the data which a laser scanner acquired in the three-dimensional space. Then we correct unevenness of the point cloud with Principal Component Analysis (PCA). We conducted evaluation test. The evaluation test verified that we can comprehend rough indoor and outdoor shape reconstruction result by 3D measurement device.
