Camera, Stereoscopic, Video
Sunday, September 03, 2006
A Stereoscopic Video Camera (with an laser illuminator) has been designed and developed that operates in conjunction with an image data processing computer. The Video Camera can locate a weld seam and map the surface features in the vicinity of the seam.
The Video Camera can scan a field of view from 0.5 inch to 2.0 inches (13 mm to 51 mm) wide and 0.5 inch to 2.0 inches deep, with a resolution of 2.0 mils to 8.0 mils (0.05 mm to 0.21 mm). The Video Camera and laser illuminator assembly measures 3 inches x 3 inches x 2.75 inches (76.2 mm x 76.2 mm x 69.9 mm) and weighs 1.5 pounds (0.7 kg).
The Video Camera consists of a CCD in the focal plane of the stereoscopic viewing optics. The output of the CCD is digitized and sent to a computer. Electronic processing identifies identical features in the right and left image. This information formulates position location from the relationship between the two images.
