Abstract
Methods and apparatuses for inspecting manholes or other voids and collecting data in a comprehensive, repeatable, and measurable manner. A sensor head is suspended and lowered into a manhole or other void. The sensor head collects data related to the condition of the manhole or void walls, and locations of defects, damage, or lateral pipe openings. The data can then be processed to provide a three-dimensional model of the manhole or void, and can be compared to previous or future data.
