Baumer at Vision 2009 (November 3–5, Stuttgart, Germany, www.messe-stuttgart.de/VISION), presented a new camera technology for high color quality requirements. Called HQ Color technology, it is based on the internal real-time Baumer CIELAB Engine to deliver with a single sensor brilliant colors that can only otherwise be realized with three-CCD cameras, the company reported. The patented algorithm also works with very sharp edges, a feature that improves the clear contour determination of cohesive color areas.
Cameras with HQ Color Technology provide higher quality with regard to color fidelity and color noise to ensure high stability with minimum color deviation between different cameras, Baumer reported. The first model to employ the technology, the TXG06ac, delivers a resolution of 776x582 pixels. Its 36x36x58-mm compact design allows installations in narrow industrial environments.
Baumer also introduced the new SX family of cameras, which incorporate Kodak's high-performance CCD sensors. Using Quad-Tap technology, these Kodak progressive-scan interline sensors combine high frame rates with very low image noise. They are available with a resolution of either 1 or 2 Mpixels. The 1-megapixel sensor is configured as a 1024x1024-pixel matrix and, depending on the number of output taps used, can achieve speeds of 120 fps. The 2-Mpixel sensor has horizontal and vertical resolutions of 1600x1200 pixels, respectively, with speeds of up to 68 fps. The industrial housing measures 52x52x72 mm. CameraLink Base serves as the digital interface for the cameras.
The company also presented its new GigE trigger device, which simplifies integration of process-relevant sensors and actuators into the camera network. With eight inputs and eight outputs, it provides many connections for the integration of light barriers and encoders, enabling basic process control while avoiding the expense of adding a programmable logic controller.
The input signals from the sensors are evaluated by the trigger device and used for the real-time control of a single camera or a group of GigE cameras. Gates or other actuators can be triggered for additional process steps based on analysis of captured images. To trigger GigE cameras directly, the trigger device is equipped with a 3-port switch. Where one port is used for the internal trigger signals, the other two ports enable the connection to the PC to receive the images from the connected GigE camera on the third port. The switch supports standard GigE cameras as well as PoE cameras.
