Abstract
According to an embodiment, a work support device includes a measurement unit and an irradiation control unit. The measurement unit measures an in-passage structure of a passage inside of which a user can work. The irradiation control unit controls an irradiation unit to emit light indicative of a work region to a corrected work position obtained by correcting work position information set based on a predetermined designed in-passage structure indicative of an ideal structure in the passage by using a result of the measurement by the measurement unit.
Claims12
A work support device, comprising:
- a sensor configured to measure a side portion of an in-passage structure of a passage;
- and
- control circuitry configured to
- control an irradiation source to emit light, indicative of a work region, to a corrected work position indicated by corrected work position information obtained by correcting, by using a result of measurement by the sensor, work position information set based on a predetermined designed in-passage structure indicative of an ideal structure in the passage, the designed in-passage structure being arranged at a position using, as a reference, a reference frame having a predetermined shape and including, as a side, a line connecting two reference lines adjacent to each other in the intersection direction,
- acquire observation information including observation points on an inside of the passage;
- acquire reference position information of a plurality of reference lines in the passage;
- calculate a position of the side portion of the in-passage structure based on the acquired observation information and the acquired reference position information;
- and
- correct the work position information to the corrected work position information based on the predetermined designed in-passage structure with reference to the reference position information and based on the calculated position of the side portion of the in-passage structure,
- wherein the control circuitry is further configured to
- acquire, as the reference position information, a position of each of the plurality of reference lines, which extend in the passage in an extension direction of the passage and arranged by being spaced in an intersection direction intersecting the extension direction,
- calculate the position of the side portion of the in-passage structure, which indicates a structure of the passage at a cross-section in the intersection direction based on the observation information and the reference position information, and
- correct the work position information to the corrected work position information such that a work position of the work position information, which is arranged on the designed in-passage structure, becomes a corresponding position on the in-passage structure.
