Rotary 3D scanning device and correction method thereof

Abstract

The invention discloses a rotary 3D scanning device and a correction method thereof. The rotary3D scanning device comprises a box body, a containing module, a sliding module, a rotating module and a 3D scanning shooting module, and the upper end portion where the box body is located is provided with a housing with an open front face; the containing module is arranged in the housing where the box body is located and located above the box body. The sliding module comprises two sliding seats and a moving seat, the two sliding seats are arranged at the two ends of the upper end face of the containing module correspondingly, a U-shaped support is arranged on the upper end face where the sliding seats are located, and meanwhile the two ends where the moving seat is located are slidably connected to the sliding seats correspondingly; the moving seat does linear reciprocating motion in the extending direction of the sliding seats; according to the device, the coordinate relation of the Z axis is determined by the 3D scanning shooting module in multiple directions by adopting the rotating module, so that the special-shaped structure of the edge position of the to-be-measured part is determined, the spatial position relation of the special-shaped structure is accurately determined, and the specific size is constructed.

Description

technical field [0001] The invention belongs to the technical field of scanning surveying and mapping, and in particular relates to a rotary-based 3D scanning device and a correction method thereof. Background technique [0002] With the increase in shipments of smart phones year by year, the camera technology and picture technology used in mobile phones have also been developed rapidly. At the same time, some application software similar to camera photo measurement is also being popularized. When measuring some workpieces with high precision requirements, the measurement accuracy is poor, which affects the measurement results. [0003] A photographing control method, photographing control device and photographing system are disclosed in Chinese patent CN105635571B. In this patent, the distance sensor installed on the selfie stick detects the object distance, assists the electronic device to focus, and increases the performance of the selfie stick. However, in actual use, w...

Problems solved by technology

In this patent, the distance sensor installed on the selfie stick detects the object distance, assists the electronic device to focus, and increases the performance of the selfie stick. However, in actual use, when the distance is used to detect the object distance, the measured object is a special-shaped surface or Special-shaped structures, when using sensors to measure, the error is relatively large, and the feedback accuracy for special-shaped surfaces is inconsistent, and it is impossible to accurately control the size of the measured object
