Abstract
A pipe inspection system employing a camera head assembly incorporating multiple local condition sensors, an integral dipole Sonde, a three-axis compass, and a three-axis accelerometer. The camera head assembly terminates a multi-channel push-cable that relays local condition sensor and video information to a processor and display subsystem. A cable storage structure includes data connection and wireless capability with tool storage and one or more battery mounts for powering remote operation. During operation, the inspection system may produce a two- or three-dimensional (3D) map of the pipe or conduit from local condition sensor data and video image data acquired from structured light techniques or LED illumination.
