Three-dimensional surround scanning device and method thereof

A three-dimensional surround scanning device, adopted to perform a three-dimensional surround scanning on a scene area, for constructing a three-dimensional model data, wherein the scene area is defined by a first length and a second length, the device comprising:

• an image acquisition element, for shooting and returning at least one two-dimensional image when being actuated;
• a first moving mechanism, for carrying the image acquisition element, making the image acquisition element perform a scanning motion along a direction of the first length when being actuated, and returning at least one position signal corresponding to the scanning position;
• a range acquisition element, disposed on the first moving mechanism, for performing back and forth scanning along a direction of the second length when being actuated and returning at least one depth information, wherein when the first moving mechanism and the range acquisition element are both actuated, the range acquisition element performs the back and forth movement along the direction of the first length corresponding to the direction of the second length, and returns the depth information with three-dimensional coordinates;
• and
• a controller, for actuating the image acquisition element, the first moving mechanism, and the range acquisition element, to control the image acquisition element, the first moving mechanism, and the range acquisition element to respectively return at least one two-dimensional image covering the scene area, the position signals, and the depth information with three-dimensional coordinates, wherein the controller reads and converts the two-dimensional image and the depth information into the three-dimensional model data.
