Inspection system and method

摘要

A method of inspecting a lateral pipe extending from a manhole, said method comprising: (a) inserting an imaging head into said manhole using a positioning system, said imaging head connected to an elongated member and comprising an imaging device adapted to convert an image to an image signal, a lens optically coupled to said imaging device, and at least one lamp suitable for projecting a light beam, said lamp having a beam that is adjustable to enable said beam to move relative said imaging device; (b) imaging a target located within said lateral pipe; (c) holding said imaging device essentially steady while imaging said target and adjusting said beam to adjust the illumination of said target.

1. A method of imaging a target at a distance using a system comprising an imaging head connected to an elongated member and comprising an imaging device adapted to convert an image to an image signal and having an optical axis, a lens optically coupled to said imaging device, and at least one lamp suitable for projecting a light beam, said lamp having a beam that is adjustable to enable said beam to move relative said imaging device, said method comprising:
(a) imaging said target; and (b) holding said imaging device essentially steady while imaging said target and adjusting said beam automatically to maximize the illumination of said target, wherein said beam is controlled automatically by one or more processors configured to determine the luminance of an image generated by said imaging device and to send a signal to move said beam until luminance is maximized.
