Modular machine vision system
Aimer Ltd has developed a modular machine vision system based on an invention which decreases the need for data processing dramatically.
Objects which are sought or followed emit or reflect different kind of light than their surroundings. If they do not they have been equipped with marks.
The signal from a camera
goes through a real-time light analyzer. With a proper camera the analyzer
can find different colours or different kind of polarization in the image.
Different colours and their combinations can be changed easily with switches.
Objects and their edges are marked electrically in the image.
When the signal manipulated by the analyzer is led to a monitor, interesting objects show brightly. In some applications the rest of the image can be darkened.
An object locator determines the location, rotation angle and size of the objects quickly and reliably. The object can be zoomed and represented on the monitor in the right attitude.
Information on the coordinates
and angle of the objects can control the robot which handles the objects.
The information can also control the code and mark recognition system.
