Image processing techniques for multi-sensor inspection of pipe interiors

T Kueny, J Starr, FJ Salotti - US Patent 11,029,257, 2021 - Google Patents
An embodiment provides a method, including: obtaining, from a multi-sensor pipe inspection
robot that traverses through the interior of a pipe, sensor data, such as structured laser light
sensor data and Light Detection and Ranging (LIDAR) sensor data, for the interior of the
pipe; identifying a pipe feature using one or more of the sensor data types; selecting an
image processing technique based on the pipe feature identified using a stored association
between the pipe feature and an image processing technique; and forming an image of the …

Image processing techniques for multi-sensor inspection of pipe interiors

T Kueny, J Starr, FJ Salotti - US Patent 11,867,641, 2024 - Google Patents
An embodiment provides a method, including: obtaining, from a multi-sensor pipe inspection
robot that traverses through the interior of a pipe, two or more sets of condition assessment
data for the interior of the pipe collected during a single pass through the interior of the pipe;
the two or more sets of condition assessment data comprising a first data type obtained
using a first sensor type and a second data type obtained using a second sensor type;
combining, using a processor, two or more image processing techniques to adjust imaging …
