Photonfocus develops camera that is optimised for laser triangulation
Together with Spanish company Aqsense Sl, Photonfocus AG of Lachen, Switzerland, has developed a camera which, it says, is optimised for laser triangulation.
The MV-D1024E-3D01 camera contains an image pre-processing module that specifically detects laser beams in triangulation applications. This enables the height profile of an inspected object to be calculated by the camera, which means that users do not have to perform any additional calculations on a computer. The newly developed 'laser line peak detector' algorithm allows sub-pixel precision determination of the line position, say the companies.
According to Photonfocus, the combination of the new algorithm with its LinLog technology enables precise measurement results to be achieved compared with cameras that feature a linear curve. The LinLog technology prevents an overexposure (saturation) of the sensor, so that sub-pixel information in the image signal is maintained even under strong reflection from the surfaces of the object that is being examined. Thus, there are advantages especially when scanning metallic, translucent surfaces, organic fabrics or textiles.
The use of the new algorithm from Aqsense and the Photonfocus LinLog technology can also minimise unwanted staircase effects, which usually appear when mixed dark and bright regions are scanned.
