Point1 : PC environment vision inspection program that allows users to apply and edit image processing and various video processing technologies to meet specifications of the user
Point2 : For inspection purposes, various interface types including analog cameras are supported. Each type has a different throughput, cable length, power, I/O synchronization, CPU usage, and it is necessary to select the appropriate type according to the inspection facility structure and purpose
Additionally, it is important to select a camera for the purpose, and there are cameras of various types and prices depending on the number of pixels, color, speed of shooting, size, etc. We help you select a low-cost/high-efficiency optimal camera.

Practical Application Cases
[Status] Determining whether parts are inserted or missing
PWA area, Manual insert parts : Check for missing inserts
Using a library of NI machine vision algorithms that can detect the shape, location, and angle of a specific pattern contained in ez-VISION, not only missing inserts but also reverse inserts and misinsertions of the product
[Status/Position] Checking the engagement of ring parts
Check whether the ring is assembled or not, it's assembled in the right position, and it's double-assembled.
Measure the length of the product's width depending on whether the ring is fastened or not and detect defects.
[Mix] Identifying product mix
Check whether the input direction of the parts is correct or whether other models are mixed in.
Defect detection by measuring the shape of a specific pattern of a part and the length of each part
[Position/angle] Calibrate robot working position
The position and angle of the product is suitable for transporting by robot.
Detect the angle of the shape position of a particular pattern and pass it on to the control unit to correct the position and angle
[Color] Illumination check
Inspect LED lighting, brightness
Check the lighting, brightness, and color using Histogram to detect defects.
[Barcode] Barcode recognition and location determination
Inspect Labeling & Printing Location and Barcode Information
Use the edge function to determine if the label & print location is defective and the barcode information is passed to the control unit.
[OCR] Character discrimination
Check to prevent products mixing by recognizing print characters
Use the OCR function to determine whether the product is defective or not
