ELEVATOR SHAFT INNER DIMENSION MEASURING DEVICE, ELEVATOR SHAFT INNER DIMENSION MEASUREMENT CONTROLLER, AND ELEVATOR SHAFT INNER DIMENSION MEASUREMENT METHOD

摘要

According to one embodiment, an elevator shaft inner dimension measuring device includes a distance measuring instrument, an imaging device and a controller. The distance measuring instrument includes a first laser rangefinder mounted to a moving object moving through an interior of an elevator shaft, and irradiating laser light on an inner wall of the elevator shaft. The imaging device includes a first camera mounted to the moving object, and imaging the interior of the elevator shaft. The controller includes a calculator, a position calculating device, and a memory device. The calculator performs an operation on distance data obtained from the distance measuring instrument, and image data obtained from the imaging device. The position calculating device estimates a motion of the moving object and calculates a position of the moving object in the interior of the elevator shaft. The memory device stores the distance data and the image data.
