High-reflection surface 3D surface measuring instrument can detect glass surface defects and scan transparent materials (mobile phone glass shell, car glass, etc.). In this sense, it is essentially a stereo measurement technology. Compared with the traditional technology, it can complete the three-dimensional measurement of points and surfaces of complex shapes and realize non-contact measurement. It has the advantages of high speed and high accuracy. These characteristics determine that it can play an important role in many fields, and its measurement results can directly interface with a variety of software. Today, it has been widely used in various fields.
The challenging task in 3D topography measurement is to accurately measure the surface of various high-reflective parts. Due to the characteristics of materials, the high-reflective objects have many problems such as high-light reflection and high-light ratio on the surface, resulting in over-exposure of the high-reflective areas in the whole image, underexposure of other areas, degradation of image appearance and loss of texture details. When the traditional structured light method is used for measurement, large data holes appear in the reconstruction results. The most commonly used method for 3D measurement of highly reflective surfaces is usually called High-Dynamic Range (HDR) technology.
CHIOPT high-reflection free-form surface 3D surface measuring instrument is a high-precision universal measuring device, which can measure aspheric surface, free-form surface and special optical elements. It combines the contact probe and optical sensor into one, automatically aligning and leveling, calibrating and defining the coordinate system, and automatically real-time error compensation. By actively tracking and measuring the unknown contour, a device can simultaneously measure the shape, contour and roughness of the object. Designed for reliable surface detection of mirror free surface, it can reliably detect the shape deviation and appearance defects of reflective components invisible to the naked eye.
Product function: 3D measurement point cloud output; Point cloud matching (measuring point cloud and surface type formula); Height error, slope error and curvature error; Surface defects: distortion (distortion), pitting, scratches, etc.
Product features：
High precision: micron level detection precision, reliable detection of shape deviation and appearance defects of mirror and reflecting surface;
High speed: the deflection method is used for measurement, and the speed is much faster than the contact detection;
Flexible application: it can be integrated into the production line or used with a manipulator, and can be used online and offline;
Customizable: all core hardware and software are independently developed and can be customized according to user needs; Transparent parts can also be directly detected without powder spraying, which is convenient to use.
