Systems for guiding a user through a workflow routine can include an inspection tool, a user interface, memory, and a processor. The processor can provide instructions via the user interface to perform a workflow routine using the inspection tool and save acquiring inspection data to memory. Instructions can direct a user to which equipment to inspect and/or how to collect inspection data associated with one or more pieces of equipment. Systems can determine which equipment is available for inspection by the user, such as via image recognition or proximity detection, and instruct a user to acquire inspection data associated with such equipment. Workflow routine instructions can be provided to the user via various devices, such as an inspection tool, smartphone, or a tablet.

Inspection workflow using object recognition and other techniques

A radio frequency (RF) imaging device comprising a display receives a three-dimensional (3D) image that is a superposition of two or more images having different image types, which may include at least a 3D RF image of a space disposed behind a surface. A plurality of input control devices receive a user input for manipulating the display of the 3D image. Alternatively or additionally, the radio frequency (RF) imaging device may receive a three-dimensional (3D) image that is a weighted combination of a plurality of images, which may include a 3D RF image of a space disposed behind a surface, an infrared (IR) image of the surface, and a visible light image of the surface. A user input may specify changes to the weighted combination. In another embodiment, the RF imaging device may include an output device that produces a physical output indicating a detected type of material of an object in the space.

A radio frequency (RF) imaging device comprises a position sensor, an RF sensor assembly, an optical sensor, a processor, and a memory. The position sensor determines a position of the RF imaging device relative to a surface. The RF sensor assembly captures RF image data representing an RF image of a portion of a space behind the surface at the determined position. The optical sensor captures optical image data representing an optical image of the surface at the determined position. The processor produces a composite image in which at least one or more portions of the RF image and one or more portions of the optical image that correspond to the same position relative to the surface are simultaneously viewable. The RF image data and the optical image data are stored in the memory in association with position data derived from the determined position of the RF imaging device.

Optical image capture with position registration and RF in-wall composite image

A radio frequency (RF) imaging device comprises an RF sensor assembly, a position sensor, a processor, and a memory. The RF sensor assembly receives an RF signal for capturing an RF image of a portion of a space behind a surface. The position sensor receives a plurality of signals respectively emitted by a plurality of position markers at known positions relative to the surface. The processor determines a plurality of angles at which the plurality of signals respectively arrive at the position sensor and determines, based on the plurality of angles and the known positions of the plurality of position markers, a position of the RF imaging device relative to the surface. The memory stores the RF image in association with the determined position of the RF imaging device. A time-of-flight or triangulation of signal data may be used for position determination.
