Embodiment Construction

[0011] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and technical solutions. Aiming at the demand for different projection modes of the auxiliary line laser group in different situations in visual measurement, a mechanical device that can quickly change the light bar projection mode, quickly adjust the light bar spacing and self-lock, such as figure 1 shown. The 12 stepper motors of this device are controlled by PLC, single-chip microcomputer, motion control card and other electrical control equipment that can emit pulses. Two of the motors control the rotation of the rotating component to change the direction of the projected light bar and realize the conversion of the projection mode. The remaining ten motors are respectively used to adjust the pitch angle of the corresponding laser, so as to realize the adjustment of the distance between the light bars.

Abstract

The present invention provides a device for cooperation control and regulation of lasers, belonging to the vision measurement field, and relates to a device for cooperation control and regulation of lasers. The device for cooperation control and regulation of the lasers comprises a box, two sets of rotation assemblies with the completely same structure, and two groups of array frames with the completely same structure. The two sets of the rotation assemblies are symmetrically installed on the box, and the two groups of the array frames are respectively fixedly connected with the two groups of the array frames. Each array frame is composed of a fundamental support and five groups of spacing regulation devices with the completely same structure. The layout of the five groups of the spacing regulation devices on the fundamental support is that: one group of the spacing regulation devices is installed in the middle, and four groups of the spacing regulation device are symmetrically disposed and respectively installed at four corners. Each spacing regulation device is fixed and connected with the fundamental support through screws, and is in a symmetry layout. According to the invention, a plurality of line lasers may be flexibly controlled, different striation modes may be projected according to different measurement requirements, and the spaces of the striations may be timely and steadily regulated. The device for cooperation control and regulation of lasers provided by the invention has compact structure, small space usage, reliable performances and easy operation, and effectively improve the effectively of the vision measurement.

Description

technical field [0001] The invention belongs to the field of visual measurement, in particular to a device for cooperatively controlling and adjusting multiple lasers, Background technique [0002] When using visual measurement technology to measure the size of large structural parts, due to the limited field of view of the camera, multiple cameras are often required to measure the measured object at the same time, and the data information measured by them is fused by splicing technology, so as to realize Dimensional measurement of large structural components. Data stitching plays a very important role in the measurement process. In order to improve the accuracy and robustness of stitching, multiple line lasers are often used to project cross grids on the surface of the measured object and extract the intersection points of the grids as data between multiple cameras. The spliced ​​feature points realize the measurement of the measured object size. When measuring the height...
