Product Description

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
