Guide to understanding Machine Vision interface standards

Machine Vision standards have evolved providing defined models of how industrial cameras communicate to a PC allowing easier implementation of machine vision technology. Vision systems can be made up of cameras, frame grabbers and vision libraries from various manufacturers. The vision standards provides compatibility between the various manufacturers for easy implementation.

Machine vision applications require some basic tasks of finding and connecting to the cameras, configuring parameters, acquiring images and dealing with events to and from the cameras.

machine vision interface  - GENICAM

In order to provide cameras from various manufacturers to work together with 3rd party software and hardware from other manufacturers and provide the tasks above, a standard must be followed. “GenICam” is the basis for this standardization, providing compatibility using a Generic Transportation layer and Generic Application programming interface. These are referred to as “GenTL” and “GenAPI” respectively. GenTL provides the communication layer and GenAPI enables camera features to be configured by analyzing a compliant XML file for the camera.

Camera manufacturers however provide unique independent features providing various advantages from one to another. Creating these unique features blur the lines of the standard, not always making a camera fully compatible with another manufacturers software. For example, an industrial camera may use the GenTL layer to be recognized but may have special features making it unique as well.

This can be very confusing to understand! IDS Imaging has a white paper explaining the machine vision interface standardization, GenTL, GenAPI and the system architecture . CLICK BELOW NOW TO DOWNLOAD!

Dalsa line scan polarization camera makes invisible visible!

Teledyne Dalsa has released the first line scan polarization camera for machine vision.  The Piranha4 polarization camera provides the capability of detecting , stress, surface roughness,  birefringence and physical properties undetectable with conventional imaging making the invisible visible!

This unique technique uses four polarization channels with a color line scan camera solving various applications, but not limited to the following:

Glass Inspection:  Glass bottles, architectural glass sheets, and automobile windshields, etc. – Enables inspection of internal stress and defects non-visible with conventional imaging

Dalsa Polorized ruler

Film inspection: transparent films, packaging films, and patterned films etc. – Detect scratches, digs, and other surface defects that are difficult to detect with conventional imaging   Dalsa Polarized scratch

Precision optics: optical lens, prisms, fibers, and micro-optical – Detect residual internal stress and thermal annealing effects
polarized - stress in sun glasses

Flat Panel Display and PCB inspection: Thin film transistors, organic LEDs, printed circuit boards etc.- inspect ITO, dust particles, films thickness, and surface defects with enhanced contrast

Carbon fibers: effectively inspect the quality of composite materials that are widely used in aircraft, aerospace, wind energy, and automotive industry

Food and material sorting: Increase sorting accuracy and detecting capability of foreign materials such as plastics, glasses, metals etc. with polarization imaging

Bio-medicine: digital pathology, in vitro cells culture, optical coherence tomography etc.- Provides additional information in birefringence tissues
Remote sensing: helps identifying special objects from natural background
And many more…

Optotune lenses solve a machine vision industry problem! 

IDS Imaging camera with Optotune lens

so
Machine Vision applications requiring the inspection of objects at various heights can become a challenge as normal lens have limited depth of field.  Objects outside of the depth of field become out of focus, limiting the vision application.  Historically, a lens with motorized focus adjustment would be implemented adding complexity, cost and long cycle times.  In reality, this challenge is applicable to any imaging application requiring refocusing due to various lens working distances.

Optotune Focus tuneable lenses solves this problem eliminating motorized zoom lenses or manual intervention.

Click here NOW for full detail specifications on tunable lenses

Adding an Optotune tunable liquid lens to the optical system on a standard C-mount lens and camera, allows refocusing of the imaging system on the fly.   When used in conjunction with distance sensors, its possible to  inspect objects of various heights, refocusing within 15 milli-seconds.

For example, vision systems using 8mm to 50mm focal length lenses can be equipped with a tuneable lens in the front, typically mounted on the filter thread.  In this configuration it is possible to focus from infinity down to about 100mm  or less if spacers are added.

This solution can be applied to industrial machine vision applications, ophthalmology, laser, microscopy, postal, packaging and laser applications to name a few.

Technology 411
 Optotune’s focus tunable lenses are shape-changing lenses based on a combination of optical fluids and a polymer membrane. The core element consists of a container, which is filled with an optical liquid and sealed off with a thin, elastic polymer membrane. A circular ring that pushes onto the center of the membrane shapes the tunable lens. The deflection of the membrane and with that the radius of the lens can be changed by pushing the ring towards the membrane or by exerting a pressure to the outer part of the membrane or by pumping liquid into or out of the container.

Advantages

A change in lens radius of several micrometers can have the same optical effect as moving the entire lens several centimeters. In turn there are several advantages

  • Optical systems can be designed more compact, oftentimes with less lenses and usually with less or no translational movement.
  • Large working distance ranges can be achieved
  • Eliminate expensive mechanical actuators resulting in a more robust design, which can be completely closed so that no dust can enter.  Essentially no moving parts for long life cycles (> 1B cycles)
  • Weight and volume is reduced in the system.
  • Low power consumption.
  • Fast response time of systems, down to the order of milliseconds.
  • Easy installation and remote focus control
  • Advanced controls for very accurate and repeatable control of the lens using Gardasofts TR-CL180 controllers
