1. A system for mapping pipes under inspection, comprising:
- a push-cable;
a sonde coupled to the push-cable, the sonde configured to be inserted into a pipe during inspection;
a locator configured to receive signals from the sonde and generate position information associated with the pipe from the received sonde signals;
a processing element configured to receive the position information from the utility locator and generate mapping information associated with the pipe; and
a non-transitory memory for storing the generated mapping information.

Abstract
In one embodiment, a pipe inspection system includes a push-cable, a sonde coupled to the push-cable, a locator configured to receive signals from the sonde and generate positional information associated with the pipe based at least in part on the received sonde signals, a processing element configured to generate mapping information from the position information, and a non-transitory memory for storing the generated mapping information.

19. A pipe inspection system for mapping a pipe under inspection, the system comprising:
-
a camera head assembly including an image sensor having a field of view (FOV) and an output for producing an image sensor data signal representing a (FOV) image; a semi-rigid push-cable assembly coupled to the camera head assembly for urging the camera head assembly along the interior of the pipe under test; a processor including; programming for comparing a plurality of (FOV) images to detect and extract image feature data representing features of the inner surface of the pipe under inspection; programming for producing apparent velocity data representing the apparent velocity of one or more inner pipe surface features with respect to the image sensor (FOV) responsive to the image feature data; and programming for producing a GUI image data signal representing a three-dimensional (3D) map of the pipe under inspection responsive to the apparent velocity data; and a display coupled to the processor for displaying to an operator a GUI image representing the 3D inner surface profile of the pipe under inspection responsive to the GUI image data signal.
