Embodiment

[0038] The best implementation example is as follows in conjunction with the aforementioned operation steps:

[0039]Laser measuring head 1 is a non-contact binocular laser measuring head. The laser light source adopts a 650nm semiconductor laser. The width of the linear laser beam is less than 1mm. A connecting joint that can adjust the pitch angle and steering angle of the CCD camera is used between the CCD camera of the acquisition system and its bracket. The high-precision arc-shaped slide rail and slider are fixed on the C-shaped measuring arm of the holographic scanner 2, and the bracket supporting the laser probe 1 is vertically fixed on the slider so that the linear laser beam passes through the center of the arc-shaped slide rail and The central axis of the lifting turntable of the holographic scanner 2. The slider can make a precise arc movement relative to the center of the arc-shaped slide rail. The bracket fixed on the slider is composed of a U-shaped frame, a d...

Abstract

The measuring system is a technique of optical-mechanical-electrical integration to obtain 3D vector information of object shape by using laser to scan object to be measured, and using computer to process scanned information data. System is composed of gauge head, C type arm, lifting rotary table, control cabinet and main control computer. User inputs basic measurement parameters. Carrying scan path planning automatically, system controls laser gauge head and lifting rotary table to complete measurement. By using arc slide rail specific to C type arm, the system implements hologram 3D laser scan without blind spot. The system possesses high adaptive capacity to environment, and anti noise capability so as to meet requirement of industrial site. The invention is applicable to detective, archaeology, 3D animation and industrial area, as well as online detection, and processing quality validation in active and automatic detection mode.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology. Background technique [0002] Under the current circumstances, most manufacturing and processing enterprises are accustomed to using 3D coordinate measuring machines for processing surface inspection and offline processing quality evaluation. It can only be used for off-line quality sampling inspection when used on the processing site, and the traditional and backward manual inspection mode is still used on the processing site. In order to solve this problem, some enterprises have repeatedly discussed with relevant domestic research departments and universities to solve this problem as soon as possible. However, due to the strong comprehensiveness of this type of subject, which involves the fields of machinery, control, measurement technology, data processing, computer software and hardware, and optics, no reasonable solution has been found. [0003] Focusing on the reverse engi...
