摘要： An optical encoding device includes a light source module, an encoding disc, and a photodetector. The light source module emits a source beam. The encoding disc is disposed on a passing path of the source beam. The encoding disc has first diffracting patterns. The first diffracting patterns include a plurality of sets of first diffracting patterns arranged along a radial direction of the encoding disc. Each set of the first diffracting patterns includes a plurality kinds of first diffracting patterns having different pattern extending directions and different pattern periods. When the encoding disc is rotating, the first diffracting patterns in each set of first diffracting patterns enter the passing path of the source beam in sequence, to cause a diffraction and form diffracted beams having different angles. The photodetector receives the diffracted beams having the different angles.

摘要： An optical encoder includes a light emitting module, a positioning device and a light separating structure. The light emitting module emits a light beam illuminating an illumination area of the positioning device. The positioning device includes light penetrating areas arranged in a dislocation manner. The light penetrating areas sequentially move into the illumination area. The light separating structure is disposed in the path of the light beam. The positioning device is disposed between the light emitting module and the light separating structure. When part of the light beam penetrates one of these light penetrating areas and is transmitted to the light separating structure, the light separating structure transmits the light to a sensing area and forms at least one first positioning optical pattern. The distance between two first positioning optical patterns formed by two adjacent light penetrating areas is greater than the pitch between the two adjacent light penetrating areas.

摘要： 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.
