visual positioning, visual identification, and visual measurement

       machine vision, as the name suggests, is the science and technology of giving machines vision, which is the use of computers to simulate biological (explicit or macroscopic) visual functions. It integrates many fields such as optics, mechanical electronics, computers, signal processing, and mechatronics. The following is a brief introduction to the three major applications of visual positioning, visual identification, and visual measurement.

1. Visual positioning application

For high-speed production line inspection, offline verification audits, or robot-guided pick and place, positioning tools are critical to successful machine vision. Positioning tools, locators or pattern finders are used to identify and determine the precise location and orientation of parts. Results can be transferred directly to material handling equipment or used to determine the location of other tools required for inspection. We collectively call this object movement positioning as mark positioning.

Location application

Locate parts location to facilitate material handling

Identify part features for tool marking

parts count

Parts classification

Verify part or feature orientation

2. Visual recognition applications

Recognition is widely used in a range of machine vision projects involving reading printed characters on products or parts and decoding 1D or 2D codes. To trace production parts, verify product batches, or grade printed codes, we design identification tools that deliver accurate results in the toughest manufacturing environments.

Identify application:

Work-in-process inventory management—verify parts moved during manufacturing

Tracking throughout the service life

Product verification—make sure the 1D or 2D code matches the printed text

Product identification and classification

Date and batch code verification

Code verification. Detect problems with identification systems for preventive maintenance

3. Vision measurement applications

Manufacturing measurement requirements range from presence verification to high-precision dimensional and tolerance inspections. Paying attention to the detection environment and image quality is equally important as the vision algorithm. Our sub-pixel measurement tools, coupled with appropriate lenses and stable light source devices, provide accuracy and repeatability guarantees to ensure manufacturing accuracy.

Measurement applications:

Is there any test?

Dimensional accuracy - geometric tolerance

Part Thickness and Uniformity
