Description

Technical Field

[0001] The utility model belongs to the technical field of three-dimensional scanners used for real-time input of three-dimensional modeling, and in particular relates to a three-dimensional scanner used for real-time input of three-dimensional modeling. Background Art

[0002] A 3D scanner is an instrument that scans the shape and appearance of an object. During use, users usually hold a 3D scanner to scan the object, which not only increases the workload of the user, but also manual scanning will inevitably result in omissions, resulting in incomplete data collection.

[0003] In order to solve this problem, a search revealed a real-time entry auxiliary device for scene 3D modeling for 3D reconstruction of a site with authorization number "CN219164619U", a groove being provided at the center of the end face of a workbench, and a rotating shaft being rotatably connected at the centers of both sides of the workbench, an arc-shaped plate being fixedly installed between the outer walls of the two rotating shafts, the arc-shaped plate being located above the workbench, a frame being connected to the arc-shaped plate, and a scanner being fixedly installed at the center of the lower end face of the frame; the utility model can drive the scanner connected to the arc-shaped plate to swing back and forth left and right above the workbench, and automatically scan all around the model placed in the groove of the workbench, which not only reduces the labor burden of the staff, but also avoids the problem that the scanner misses the model during scanning, which leads to defects in the digital model created in the virtual world.

[0004] However, through observation, it is found that the device still has the following problems during actual use: it drives the sector gear to rotate through the rack plate, and then drives the arc plate to swing back and forth above the workbench. However, the shape of the sector gear causes the arc plate to have a small adjustable angle, resulting in the scanner having a blind spot when scanning the object, which can easily cause incomplete scanning data collection and affect the smooth progress of the next step of modeling.
