Colour camera resolves small features

Edited by the Manufacturingtalk editorial team Apr 25, 2005

High resolution allows a colour camera to be used to resolve small features while maintaining a large field of view and a region of interest controls and multiple decimation modes add flexibility.

The PL-A782 is a high-resolution, 6.6 megapixel (2208 x 3000) colour camera designed specifically for industrial inspection applications.

Fully IIDC 1.3 (DCAM) compliant, the PL-A782 uses a standard FireWire interface for plug-and-play operation with the host computer.

This high resolution allows the camera to be used to resolve small features while maintaining a large field of view.

Region of interest controls and multiple decimation modes make the PL-A782 a flexible choice.

Features such as trigger and general purpose output controls add a level of functionality beyond the IIDC standard, providing excellent performance for the price.

On board Flat Field Correction provides image quality similar to high-end CCD cameras.

The PL-A782 connects to the computer via a single FireWire cable that supplies power to the camera and allows high-speed data communication.

No special or expensive frame grabber card is required.

The camera's two FireWire ports allow multiple cameras to be connected together ('daisy chained') on a single FireWire bus.

The external trigger allows cameras to be synchronised with each other or with external systems.

In machine vision, it may be argued that 6.6 megapixels may represent too much data.

The PL-A780 can, in one image, view a surface area that would require 25 image capture operations with a VGA resolution camera.

Step and repeat motion control systems that use a VGA camera can be replaced with a single fixed camera.

With the flexible ROI and pixel addressing modes, the resolution is user controllable.

The PL-A780 will be able to capture a wide field of view while providing excellent resolution.

In addition, it can also selectively image only the Region Of Interest within the full field of view, reducing the bandwidth and increasing the frame rate.
