2D imaging technology
· 2D imaging overview, that is, the graphic only exists in the XY axis plus grayscale information or color RGB value. The comparison information in the gray graphic or color picture is used to process the feature information
· There are many industries, lithium battery, medical care, 3C, semiconductor, hardware, etc., so as to achieve various appearance testing, identification, positioning, measurement, judgment and other functions, which can help enterprises significantly improve production efficiency, automation and intelligence degree
· Advantages: low cost, easy installation, debugging and maintenance, wide range of use, disadvantages: difficulty in testing without high information, appearance detection high demand
2.5D imaging technology
· You can control the ultra -high speed synchronization by making the CMOS sensor and lighting pattern.
· Test the various appearance defects that occur on the surface, metal, and glass surfaces that cannot be judged without artificial visual vision
· Advantages: Slight scratches, concave pits, bumps, fingerprints, etc. The detection items that are difficult to recognize the eye recognition can be clearly treated
· Disadvantages: High cost, not available in high -speed exercise detection types
3D imaging technology
· The principle overview, that is, the laser emitted by the laser light source is transmitted by the lens to form a beam of line -shaped laser. The laser will reflect after the product surface is hit.
· Through the form of exercise scanning, multiple contour combinations form 3D images
· Advantages: For high -measured project requirements, you can get a good solution, such as pinholes of sealing nails and top cover welding
· Disadvantages: high cost, visual blind zone in imaging
Light three -dimensional imaging technology
· The principle overview, that is, calculate the gradient of the surface of the object according to the light strength of multiple images taken in different light sources to obtain the three -dimensional information of the image
· The optical three -dimensional imaging technology can also be comparable to 2.5D imaging, which is mainly used to detect the bump special information on the material
· Advantages: Low cost, just need to face the camera and the corresponding number of light or the multi -angle ring -shaped light source
· Disadvantages: The imaging field is small, and it cannot be used for the appearance detection on the large surface
Time -sharing frequency imaging technology
