Abstract: A three-dimensional modeling method and a three-dimensional modeling system are provided. The three-dimensional modeling method includes the steps of: performing a 360-degree three-dimensional scan on a measured object to obtain regional scan data corresponding to a plurality of different scan areas of the measured object; registering the regional scan data to form 360-degree three-dimensional scan data, wherein the 360-degree three-dimensional scan data include three-dimensional spatial coordinate data, curvature data and scan area data of the measured object; basing on the 360-degree three-dimensional scan data to search morphing model data from a database unit; a step of comparing the 360-degree three-dimensional scan data and performing registering and morphing processes on the morphing model data to construct compensated-template three-dimensional model data; and, basing on the compensated-template three-dimensional model data to fill at least one unknown area of the 360-degree three-dimensional scan data.

Abstract: A device for acquiring depth image, a calibrating method and a measuring method therefore are provided. The device includes at least one projecting device, at least one image sensing device, a mechanism device and a processing unit. The projecting device projects a projection pattern to a measured object. The image sensing device is controlled to adjust a focal length and focus position, and therefore sense real images. The mechanism device adjusts a location and/or a convergence angle of the image sensing device. The processing unit calibrates the at least one image sensing device and generates a three dimension (3D) measuring parameter set at a model focal length according to a plurality of image setting parameter reference sets corresponding to a model focal length and a plurality of default node distances, respectively, and then estimates a depth map or depth information of the measured object.

Abstract: A calibration method of a depth image capturing device including a projecting device and an image sensing device is provided. At least three groups of images of a calibration board having multiple feature points are captured. Intrinsic parameters of the image sensing device are calibrated according to the at least three groups of images. Multiple sets of coordinate values of corresponding points corresponding to the feature points in a projection pattern of the projecting device are obtained. Intrinsic parameters of the projecting device are obtained by calibration. Multiple sets of three-dimensional coordinate values of multiple feature points are obtained. An extrinsic parameter between the image sensing device and the projecting device is obtained according to multiple sets of three-dimensional coordinate values, the multiple sets of coordinate values of corresponding points, the intrinsic parameters of the image sensing device, and the intrinsic parameters of the projecting device.
