High-speed cameras are often used in factory automation, research, or destructive testing to capture a sequence of events at high speed. This webcast - Fundamentals of Machine Vision: High-Speed Imaging - will show the basic elements behind the design of today?s high-speed cameras and the benefits these cameras can bring to motion analysis applications.

Engineers and systems developers will learn how high-speed camera vendors achieve these fast frame rates, how to deploy the cameras, and how image analysis software can be used in numerous applications to track and analyze captured image sequences.

This Webcast - 3-D Imaging for Machine Vision will provide engineers and system integrators with the basic information tools they can use to implement 3-D machine vision in their applications. The webcast will introduce the human visual system, 3-D machine vision, and 3-D vision methods and applications. It will show the audience how to extract 3-D information from an image, and thus enable many important tasks, including robot grasping, navigation, and traffic analysis.

The webcast will highlight some of the problems, solutions, and typical applications of different types of 3-D vision:

• Single-camera methods using interpretation of object size, texture gradients, occlusion, color intensities, and angle of observation
• Single-camera methods where one camera is mounted on an articulated arm (or robot) and features of the object used to compute its location in 3-D space
• Dual-camera methods (or stereo cameras) using epipolar geometry
• 2.5-D methods: what this means, operating principle, computation of depth measurement
• Laser-based 3-D imaging: triangulation 3-D laser scanner, principles, operation, and accuracy
• Projected striped light imaging: structured-light 3-D scanner, generation of stripe pattern, principles of operation, calibration, speed, range
• Time of flight imaging: pulsed light sources using lasers, photonic mixer devices using LEDs

To meet changing market demands, vendors of solar cells and modules are seeking ways to increase yields and improve quality while lowering costs. In turn, these vendors are demanding automated inspection systems based on machine vision.

This Webcast - Machine Vision for Solar Cell Inspection - will help engineers and system integrators understand how to integrate hardware subsystems, solar cell transport, image acquisition and processing, lighting, and data management software. It will examine both the mechanical constraints that must be considered when developing solar cell wafer inspection systems and how image processing tools such as blob analysis and edge detection can be used to measure the features of each wafer.

Manufacturers use color vision to solve three primary vision applications: part verification, sorting, and defect inspection. This Webcast - Using Color in Machine-Vision Applications - will look at different color models that can be used to perform these types of inspections and show through specific examples how they are used in each of these applications. It will provide engineers and system integrators with the basic information tools so that they can combine machine vision and color in their applications to meet manufacturing challenges. Archer will discuss the applications in terms of the OEM components that are used, such as lighting, cameras, and machine vision software.

Areas of focus include:

• Color cameras and how to obtain a color image from an RGB-based camera
• Bayer interpolation and how it is performed, showing the different methods and results
• Camera calibration including the effects of different lighting conditions on color images
• The primary color models used in machine vision: RGB, HSI,
CIE 1931 XYZ color space, and its derivatives such as CIELUV, CIEUVW, and CIELAB
• Which color models are best for which types of application
