  • High-speed 3-D Camera
May 2010
SICK Inc.Request Info
MINNEAPOLIS, May 28, 2010 — For improving uptime in packaging, automotive and electronics applications, Sick Inc. has launched a high-speed 3-D camera that measures color and the 3-D shape of objects, resulting in more reliable decision making and increased throughput and product quality. The ColorRanger E eliminates the need for several different cameras for the same task, which reduces solution cost and complexity.

The camera solves various inspection tasks by measuring shape, contrast and surface defects to ensure product quality and production reliability. It provides high-resolution RGB color at up to 3072 pixels per channel, with on-chip white balancing and spatial correction. With simultaneous 3-D and color information at more than 11 kHz, multiple inspections can be performed in parallel at full production speed.

It uses laser triangulation to extract the true 3-D shape of objects, regardless of their contrast or color. Using MultiScan technology, it can measure contrast, laser scatter and color simultaneously. It includes a Gigabit Ethernet interface.

When height, shape or volume is important to the production process, 3-D imaging is used. To ensure quality or to make a grading decision, it is often necessary to consider the color of the parts/objects produced; for example, when grading fruits and vegetables, when verifying shape and baking degree of baked goods, for board grading in the wood industry, for quality assurance of electronic assemblies, and for fill level and color verification in the cosmetics and pharmaceutical industries.

A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
The apparent difference in brightness between light and dark areas of an image. For a light target against a dark background, contrast is computed as follows: where Lt is the luminance of the target and Lb is the luminance of the background.
