Studies in Machine Vision at MIT and TX-O Computer

The Eye of a Robot: Studies in Machine Vision at MIT and TX-O Computer (1959)

The first of two films shown here, Eye of a Robot (to 18:30) summarizes computer vision research being carried out in the 1950s at the MIT Laboratory for Artificial Intelligence, under the direction of Marvin Minsky and with Patrick Winston and Berthold Horn supervising the robotics work. The film shows how "experimental computer programs extract line drawings from pictures and use knowledge about the three-dimensional world, and also how new ideas about artificial intelligence are used in these processes." The second film is silent and shows the TX-O computer at work, e.g on a tic-tac-toe game. Courtesy of MIT Museum. View more MIT150 videos at Multimedia.

3D Machine Vision is here!!

In numerous machine-vision applications, solo or multiple cameras are used to capture two-dimensional (2-D) views of objects that are then analyzed for possible defects. Although analyzing these 2-D views is useful, many applications such as robotic pick-and-place systems require stereo images to perform this task. In other applications, such as surface analysis, it may be necessary to create a 3-D profile of an object to visualize any 3-D deformity that may be present.
Today, various methods exist to perform 3-D imaging. Perhaps the most popular of these are stereo-based vision methods that can use one or more cameras to extract information about the relative position of objects within a field of view. In this manner, depth information can be used, for example, to allow vision-guided robots to effectively pick and place objects located randomly within a bin. The data can also be used to reconstruct a 3-D model of the part for distance, angle, and area measurement.

New IMPACT software from PPT Vision

New IMPACT software from PPT Vision to support JAI Camera

The recently released IMPACT 10.2 software supports the M-Series integrated vision system family, which now features the model CM-140GE-UV ultraviolet camera and model CM-030GE-RH remote-head camera from JAI. With the machine-vision software, images can be stored in a temporary circular image history file so the operator can move forward and backward through images and run inspections under controlled conditions. New tool setups simplify Data Matrix, Serial, and TCP/IP tools. Drag-and-drop programming enables quick navigation for machine-vision system operators.

European vision market was forecast to grow 5%

The European vision market was forecast to grow 5% in 2010 but the European Machine Vision Association (EMVA) has recently announced that growth was nearer 35%. In addition, the European Machine Vision Industry Report 2011, published by the EMVA, predicts further growth of 20% in 2011. This has been fuelled by the accessibility of vision and imaging technologies, easy to use of software and the flexibility of interfaces and camera technology.

A major contributor to this trend is the increasing demand placed on industry to be more cost efficient and to reduce defects, improve quality control and to eliminate human error through the use of automation.

Automation is having a significant influence on the industrial vision market as the manufacturing sector strives to ensure competitiveness in response to the threats posed by lower labour costs in other parts of the world. Industry has also been able to benefit from technology advances, developed for the demanding security and defence sectors, which have been driving improved performance and reducing system prices. Vision is also expanding outside its natural home of industrial production and is moving into areas such as agriculture, security, surveillance, logistics, life science, medical technology, retail, sports and many other walks of life. It would seem that this trend is no ‘flash in the pan’. Another report, ‘Global Machine Vision and Vision Guided Robotics Market (2010-2015)’ published recently by US based Marketsandmarkets predicts significant growth for the machine vision and related components market throughout the world during this period.
