Abstract
This position detecting system is provided with: a target object shape extracting part which extracts a target object as a target object shape from a three-dimensional shape in an indoor space, and acquires a position of the target object shape; an identification information acquisition part which acquires, on the basis of data reported from the target object, target object identification information for identifying the target object; and an identification information associating part which associates the target object shape with the target object identification information.
Claims16
A position detecting system comprising:
- a computing device;
- and
- a non-transitory computer-readable memory storing instructions that, when executed by the computing device, cause the computing device to perform operations comprising:
- an object shape extracting operation of extracting an object shape of an object from a three-dimensional shape obtained by a three-dimensional measuring device and acquiring the object shape and a position of the object;
- an identification information acquisition operation of acquiring target object identification information related to a target object, which is one of a plurality of the objects, wherein a motion sensor is mounted on the target object;
- a position estimation operation of outputting position estimation information that estimates the position of the target object, wherein the position estimation information is estimated from each of a moving distance and a moving direction of the target object detected by the motion sensor;
- and
- an identification information associating operation of associating the target object identification information with the object shape by using the position of the object acquired by the object shape extracting operation and the position estimation information.
