摘要： A locator system for locating buried utilities such as conduits, cables, pipes or wires incorporates image-capturing and position and orientation measuring devices such as magnetic compass, accelerometers, gyros, GPS, and DGPS. The system may include other sensors such as gas concentration sensors. The system associates images captured during the locate process with buried utility position data and the other sensor data. These data and images may be further associated with terrain images from satellites or aerial photography to provide a highly precision map and database of buried utility locations and visual images of the burial site. Information so obtained may be transferred to a hand-held personal communication device (such as a smart phone) capable of displaying an augmented or virtual reality display showing the location of buried utilities in combination with photo-images and/or terrain maps.

摘要： An apparatus is disclosed for magnetically sensing and computing and displaying cable distance, and computing and displaying other user-selectable information in a pipe inspection system. At least two permanent magnets are mounted in spaced apart fashion, on either a frame, or a rotatable member supported on the frame for rotation about an axis. A magnetic sensor is mounted on the other one of the rotatable member or frame on which the magnets are not mounted, so that either the magnets rotate around the magnetic sensor or the magnetic sensor rotates between the permanent magnets. The magnetic sensor generates signals representing changes in at least two axes in a composite magnetic field generated by the permanent magnets.
