The above detection hardware solution adopts Wei Shi image industrial cameras and lenses, and the software uses self-developed intelligent software, which can quickly achieve customer requirements.

Here are some of the functions of SmartView SVMS intelligent software:

1. Multiple shapes of ROI: provide rectangle, circle, line, rotated rectangle, polygon ROI, and measurement elements can be freely combined;

2. Multi-detection function: the same product can realize multiple function detection at one time;

3. Quickly create a visual project: Setting all programs requires only the mouse to drag the corresponding detection tools to combine to quickly establish a detection project;

4. Positioning function: Provide a variety of positioning functions, enabling workpieces to be placed at will and the size to be detected;

5. Support Excel format: The test results are saved in Excel format, and users can use Excel's powerful data analysis functions for data statistics;

6. Multiple camera inputs: support the image acquisition function of MV-EM cameras and various mainstream cameras at home and abroad;

7. Multiple communication functions: support RS232, TCP / IP, I / O output.
