This invention relates to the field of augmented reality (AR) technology, and in particular provides an elevator inspection method and system based on AR technology. The method includes receiving a beam and analyzing its phase hysteresis; converting each phase hysteresis value into spatial coordinate values ​​according to the spatial arrangement order of directional reflection units to obtain a longitudinal cross-sectional profile dot matrix composed of spatial coordinate values; synchronizing the longitudinal cross-sectional profile dot matrix with real-time spatial attitude parameters output by an orientation sensing component moving with the inspection device to obtain a virtual ruler grid; projecting the virtual ruler grid onto the surface of the elevator component under inspection; acquiring the offset vector between the projected image of the virtual ruler grid on the component surface and the actual contour of the elevator component under inspection; comparing the offset vector point-by-point with a preset allowable offset threshold to obtain a quantified value of the deviation degree. This invention achieves automated, high-precision, and visualized inspection of elevator component morphology, providing reliable data support for elevator safety status assessment.

An image forming apparatus includes a first sensing portion, a stop processing portion, and a rotation processing portion. The first sensing portion senses a sheet on a downstream side of the fixing nip portion in a conveyance direction of the sheet. The stop processing portion stops an image formation process in a case where the first sensing portion does not sense the sheet before a specific time elapses after a timing at which a front end of the sheet in the conveyance direction reaches the fixing nip portion while the image formation process is in execution. The rotation processing portion reversely rotates a fixing member by an amount of rotation corresponding to a difference between a specific distance and length of the sheet in the conveyance direction in a case where the image formation process is stopped and the length is less than the specific distance.

This invention discloses a device and method for determining the stratigraphic attitude in an exploration well. A circular track is circumferentially arranged on the inner wall of the housing. The orientation sensing component includes a compass located below the housing and a first rotating and moving mechanism connected to the compass. The first rotating and moving mechanism is mounted on the circular track and can move along the track, driving the compass to move circumferentially along the inner wall of the exploration well, ensuring that the compass dial is always parallel to the inner wall at the corresponding position. The image acquisition component includes a camera module located below the housing and a second rotating and moving mechanism connected to the camera module. The second rotating and moving mechanism is mounted on the circular track and can move along the track, driving the camera module to move circumferentially along the inner wall of the exploration well, ensuring that the camera module is always perpendicular to the compass dial. This invention provides a complete and accurate description of stratigraphic attitude, eliminating the need for geotechnical technicians to personally enter the exploration well for observation.
