ICK recently won the award for applied machine vision at the Vision Awards in Stuttgart, Germany, with its ColorRanger E camera. This is newest member of the company’s 3D
camera product line. The cameras are used as a key vision component by manufacturers and vision integrators worldwide. They solve various inspection tasks by measuring shape, contrast, and surface defects, to ensure product quality and production reliability. The ColorRanger E expands the inspection possibilities further by also providing high-resolution RGB colour at up to 3072 pixels per channel. With simultaneous 3D and colour information at more than 11 kHz, multiple inspections can be performed in parallel at full production speed. 3D imaging is ideal where height, shape, or
volume is of importance for the production process. However, to make a complete quality or grading decision, it is often necessary to also consider the colour of the parts produced. This is, for instance, common in grading fruits and vegetables, shape and baking degree verification of baked goods, board grading in the wood industry, quality assurance
of electronic assemblies, and fill level and colour verification in the cosmetics and pharmaceutical industries. By considering both 3D and colour, more reliable inspections can be performed which improve product quality and reduce waste (Fig. 1). ColorRanger combines the functionality of a 3D camera and a line-scan colour camera. With SICK’s proprietary MultiScan technology, the camera can be configured to provide several measurements at the same time, including 3D shape, laser scatter, colour, and monochrome, according to the exact need of each specific application. As a result, says SICK, one ColorRanger can
replace several other cameras, which reduces the system size as well as the cost for hardware, integration, and maintenance. In addition, since the different measurements come from the same camera system, it is easier to combine data for analysis.
ColorRanger delivers high-quality 3D and
multi-linear colour data, including RGB, near IR, and monochrome without IR content, on a gigabit Ethernet communication interface. It has a separate row of pixels for each colour, which give full colour
