Pipe inspection system with selective image capture

摘要

Various pipe inspection systems include a camera head operatively connected to the distal end of a push-cable. Images may be automatically captured at predetermined distances of travel, or may be automatically captured based on the output signals from the auto-focus, auto-exposure and/or auto-white balance engines indicating, for example, that the camera motion within the pipe is substantially zero. Images may be captured in an automatic mode at predetermined intervals as the camera head travels within the pipe or in an override mode initiated by operator command. The system may include a data transmission circuit that transmits data between a plurality of nodes at a frequency that does not substantially interfere with a normal base band video transmission frequency.
