Laser scanning technology does have some requirements for the measured object to ensure accuracy and efficiency of scanning.



The following is a specific analysis of the requirements for the tested object:

Surface characteristics:
The surface of an object needs to have a certain degree of reflectivity so that the laser beam can generate sufficient reflected light signals on the surface of the object. If the surface of the object is too smooth or specular, it may cause excessive reflection of the laser beam, affecting the scanning effect.
For certain objects that require highlighting details, it may be necessary to apply a developer to increase the surface's diffuse reflection effect, helping the laser scanning system better capture details.

Stability:
During the scanning process, the measured object should remain stationary or move steadily. Because laser scanning obtains information on the surface of an object through precise positioning and control of the laser beam, if the object moves during the scanning process, it may lead to inaccurate scanning data.
For objects that require flipping and scanning, it is necessary to fix three small steel balls and other markers in the shape of the product on the object, so that the results of multiple scans during reverse modeling can be fitted through the markers.



Size and shape:
Laser scanning technology can process objects of various sizes and shapes, but different scanners may have certain limitations on the maximum and minimum scanning sizes.
For large objects or objects with complex shapes, it may be necessary to use higher performance scanners or use multiple scanning and splicing methods.

Material:
Laser scanning technology is usually applicable to various materials, including metal, plastic, wood, etc. But for certain special materials, such as transparent materials or strong absorbing materials, special scanning techniques or methods may be required.



Environmental requirements:
Laser scanning equipment has certain requirements for environmental factors such as light, temperature, humidity, etc. During the scanning process, strong light source interference should be avoided as much as possible to ensure a relatively stable scanning environment.

Data accuracy and resolution:
Laser scanning technology can provide data acquisition methods with different densities to meet the needs of different precision and resolution. When selecting scanning equipment, it is necessary to determine the required accuracy and resolution based on specific application scenarios and requirements.

In summary, the requirements of laser scanning technology for the tested object mainly focus on surface characteristics, stability, size and shape, material, and environmental requirements. In practical applications, it is necessary to choose appropriate scanning equipment and technical parameters based on specific scanning requirements.
