Abstract: A 3D measuring equipment and a 3D measuring method are provided. The 3D measuring equipment includes a base, a fixture, a measuring device, and a controller. The fixture is disposed on the base for an object to be measured to be disposed thereon. The fixture has a plurality of rods. The heights of the rods are adjustable. The measuring device is installed on the base and is movable relative to the fixture. The controller is connected to the measuring device and the fixture and configured to perform the following. The heights of the rods are adjusted according to 3D model data of the object to be measured to support the object to be measured. The measuring device is driven to move relative to the fixture to measure the object to be measured.

Abstract: A building method and a building system for panorama point cloud data are provided. The building method for panorama point cloud data includes the following steps. At least one reference geometric object located at an overlap region of two adjacent three-dimensional capturing devices is captured by the two adjacent three-dimensional capturing devices to obtain two reference point cloud sets. A reference feature plane is obtained from each of the reference point cloud sets. A coordinate transformation matrix is obtained according to the reference feature planes. A plurality of real-time point cloud sets are obtained by the three-dimensional capturing devices. The coordinate transformation of the real-time point cloud sets are performed according to the coordinate transformation matrix, and the real-time point cloud sets are combined to obtain the panorama point cloud data.
