Three-dimensional scanner for animation modeling

Abstract

The invention discloses a three-dimensional scanner for animation modeling, and belongs to the technical field of three-dimensional scanners. The scanner comprises a scanning box, an annular rack is fixedly arranged at the upper end in the scanning box, a U-shaped block is arranged on the inner side of the annular rack, an output shaft of a motor extends into the U-shaped block and is fixedly sleeved with two limiting wheels in an up-down structure, a gear is arranged in the U-shaped block, a cylinder is arranged on the lower side of the U-shaped block, a three-dimensional scanner body is slidably connected to the outer portion of the cylinder, the gear and the cylinder drive the three-dimensional scanner body to complete circular motion and lifting motion through a motion switching mechanism, and rotation of the gear and rotation of the cylinder are intermittently carried out and are respectively driven through forward and reverse rotation of the same motor. The structures are in close fit, the shape (geometric structure) and appearance data of an object or an environment can be overall scanned, an overall three-dimensional model can be directly obtained, accurate data collection is carried out on the overall three-dimensional model, and the situation that three-dimensional data errors are large due to the fact that the data are obtained by moving the object is avoided.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional scanners, and more specifically, relates to a three-dimensional scanner for animation modeling. Background technique [0002] A 3D scanner is a scientific instrument used to detect and analyze the shape (geometric structure) and appearance data (such as color, surface albedo, etc.) of objects or environments in the real world. The collected data is often It is used for 3D reconstruction calculations to create digital models of actual objects in the virtual world. The prior art publication number is CN206248035U, which provides a three-dimensional scanner for animation modeling. The device is provided with a rotating jacket, the upper end of which is connected to the upper motor drive, and the lower end is fixed with the lower motor, one end of which is connected to the side wall of the rotating jacket.

The prior art publication number is CN206248035U, which provides a three-dimensional scanner for animation modeling. The device is provided with a rotating jacket, the upper end of which is connected to the upper motor drive, and the lower end is fixed with the lower motor, one end of which is connected to the side wall of the rotating jacket. Affixed; a sliding table reciprocating along its axial direction is installed on the lead screw, and a scanning head is installed on the sliding table; the literature of the prior art publication number CN212320651U provides a kind of three-dimensional scanner for animation modeling, through lifting The barrel can raise and lower the three-dimensional scanner, so that the object can be scanned three-dimensionally. Although the device has many beneficial effects, it still has the following problems: the device has a moving trolley, which is meaningless for the usually fixed scanner. It is not big, and the above-mentioned device can only scan up and down or translate, and cannot scan the shape (geometric structure) and appearance data of the object or environment as a whole. The scan is not comprehensive, making it impossible to directly obtain the overall 3D model, resulting in incomplete data , or scan it in three dimensions by moving, resulting in large errors in the three-dimensional data. In addition, the existing device needs to be equipped with multiple driving structures to complete multi-directional scanning, resulting in large volume and weight of the entire device, and high cost. Considering the scanning process It can continue along the same direction, so how to realize comprehensive scanning through a driving structure is the direction of improvement. In view of this, we propose a 3D scanner for animation modeling
