What are the advantages of 3D machine vision compared with 2D machine vision?

       With the development of technology, machine vision        in the past usually refers to 2D vision systems , that is, taking plane photos through a camera, and then identifying objects through image analysis or comparison. The characteristics of objects on the plane can be seen, which can be used for lost/now detection, Discrete object analysis pattern alignment, barcode inspection and optical character verification, as well as various 2D geometric analysis based on edge detection.

Since 2D vision cannot obtain the spatial coordinate information of an object, it does not support shape-related measurements, such as object flatness, surface angle, volume, or features that distinguish objects of the same color, or between object locations with contact sides. 2D vision measures the contrast, and thus measurement accuracy, of an object, which is particularly dependent on lighting and color/grayscale changes and is susceptible to variable lighting conditions.

Therefore, 3D machine vision is becoming more and more popular as the demand for accuracy and automation continues to increase. The industry believes that the transition from 2D to 3D will become the fourth revolution after black and white to color, low resolution to high resolution, and still images to movies.

Compared with 2D machine vision, 3D machine vision has the following advantages:

1. Online detection of fast moving targets for shape and contrast

2. Eliminate errors caused by manual inspection

3. 100% online quality control of parts and components

4. Minimize inspection cycles and recalls

5. Maximize production quality and production

6. Contrast is constant, ideal for inspecting low-contrast objects

7. Not sensitive to small light changes or ambient light

8. Easier multi-sensor setup for large object detection

To choose the best visual inspection solution, we first need to judge the characteristics of the inspection object, combine the advantages of 2D and 3D, and choose the most competitive solution. Of course, you can also call the Xinxiwang hotline: 028-62705808  and we will work together to choose a plan that suits you.
