Surface Inspection

2
-
D and 3
-
D defects such as
shrink holes, pores and
indentations can be reliably
recognized in different test
areas and then classified
based on the type of defect.
Part and area contours are
checked for dimensional
accuracy, fractions and
notches.

MACHINE VISION


Quality Inspection in Packing
Industry


Technological
improvements have
made Machine Vision
accessible to small
-

and
medium
-
size packagers
so they can achieve
improved results and
even pursue brand risk
avoidance to maintain
consumer and retailer
confidence.


MACHINE VISION

Automotive Industry


In the automotive
industry, machine vision
systems are used to
guide industrial robots,
gauge the fit of stamped
metal components, and
inspect the surface of the
painted vehicle, weld
seams, engine blocks
and many other
components for defects.


MACHINE VISION

Usage Industries


Used almost in all industries


Engineering


Automotive


Pharmaceuticals


Food


Metals


Glass

MACHINE VISION

Objectives


Identify and set up machine Vision related
infrastructure


Create awareness about MV technology and its
applications


Create trained & quality manpower


Facilitate research in thrust areas of Machine
vision such as 3D object recognition, low cost MV
solutions, develop new concepts and
methodologies
