Optical path design technology

Optical path design technology is mainly aimed at measuring parts with special materials, complex features, and small sizes. When conventional light source image effects or structural space cannot meet the measurement requirements, special optical path structure design can be carried out based on in-depth analysis and evaluation of light characteristics and measurement requirements. , obtain high-quality image effects and achieve precise measurement.
2D image stitching technology

2D image splicing technology is mainly aimed at product measurement in large field of view and high-precision scenarios. By collecting multiple high-resolution images of different parts of the product, it extracts common feature points in each image and constructs an affine transformation matrix; through matrix operations , merge multiple pictures into one seamless, high-definition image. Different from traditional splicing based on region correlation, this technology combines image preprocessing, registration, fusion and boundary smoothing technology to achieve high-precision splicing based on image features.
3D image space splicing technology

3D image space splicing technology is mainly aimed at three-dimensional space size measurement. Through three-dimensional matrix transformation, multiple three-dimensional point clouds are affine to the same spatial coordinate system to form a full-angle spatial three-dimensional model. The company has designed a high-precision calibration board for multi-faceted image splicing, which combines image preprocessing, feature point positioning, affine, and image fusion technologies to achieve high-precision splicing.
Two-dimensional and three-dimensional coordinate system conversion technology

1、At the same time, the features of the same object in two-dimensional plane and three-dimensional space are extracted, and technical means such as rotation, scaling, and projection are used to obtain the matching relationship between two-dimensional features and three-dimensional features, thereby calculating the transformation matrix of the space and plane coordinate systems.

2、Using a combination of line laser and plane camera, it combines the technology of laser three-dimensional imaging to capture corner features and plane camera to capture plane peripheral features. Through calibration, the transformation matrix of the three-dimensional and two-dimensional coordinate systems is obtained, and the features in the three-dimensional coordinate system are Projected into a two-dimensional coordinate system.
