Embodiment Construction

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.

[0035] Such as figure 1 As shown, the preferred embodiment of the present invention provides a data stitching method based on non-contact optical scanning detection, which includes the following steps:

[0036] Step S1: Fix the top positioning block 1 on the support frame 5, fix the support frame 5 and the bottom positioning block 4 on the measurement platform, fix the fixture 3 on the bottom positioning block 4, and clamp the product to be tested 2 on the fixture 3 up;

[0037] Step S2: Use the non-contact optical scanning detection equipment to collect multi-angle data of the product under test 2, the top positioning block 1, and the bottom positioning block 4 until all the data of the product under test 2, the top positioning block 1 and the bottom positioning...

Abstract

The invention discloses a data splicing method based on non-contact optical scanning detection, and the method comprises the steps: a to-be-detected product and two positioning blocks being kept relatively static, thereby guaranteeing that any data image obtained through scanning detection comprises the data of the to-be-detected product and the two positioning blocks at the same time, carrying out the multi-angle collection; acquiring a plurality of data images, importing the plurality of acquired data images into data acquisition software, and registering data of two positioning blocks by using a registration function of the data acquisition software so as to complete position calculation and data splicing of the two positioning blocks. The data of a product to be tested and the data ofthe two positioning blocks are included in each data image at the same time, after data splicing of the two positioning blocks is completed, data splicing of the to-be-detected product is also completed, the data splicing precision is high, reference points do not need to be pasted, time and labor are saved, the use cost is reduced, and the method can be well suitable for data splicing of small-size parts, blades, thin-wall parts and other parts.

Description

technical field [0001] The present invention relates to the technical field of non-contact optical scanning detection, in particular to a data splicing method based on non-contact optical scanning detection. Background technique [0002] Non-contact optical scanning inspection is widely used in the size measurement of auto parts and aerospace rough products. Optical scanning inspection equipment needs to inspect the product from multiple angles and all directions during inspection. Multiple pieces of data generated during the inspection process It is necessary to use the overlapping area of ​​the product to register the stitching or paste the reference point to locate the stitching. [0003] Specifically, the method of registering and splicing using product overlapping areas is to perform data splicing based on features. For example, the existing patent CN106767524A uses a three-dimensional high-precision scanner to obtain three-dimensional point cloud data at various angles...
