Abstract

An inspection device includes a wearable camera attached to a worker that images an inspection object, and a laser pointer that indicates an imaging region of the wearable camera to the worker. The laser pointer is attached to the worker to emit a laser beam in a direction parallel to a line of sight of the wearable camera such that a relative distance between a light point of the laser beam and the imaging region of the wearable camera is constant and does not vary depending on a distance between the laser pointer and the workpiece.

First claim

The invention claimed is:

1. An inspection device used by a worker for inspection of an inspection object, comprising:
a wearable camera attached to the worker that images the inspection object;
an indication unit that indicates an imaging region of the wearable camera to the worker;
wherein
the indication unit includes a laser pointer, and
the laser pointer is attached to the worker to emit a laser beam in a direction parallel to a line of sight of the wearable camera such that a relative distance between a light point of the laser beam and the imaging region of the wearable camera is constant and does not vary depending on a distance between the laser pointer and the inspection object.

2. The inspection device according to claim 1 , wherein
the laser pointer repeatedly switches between a lit state and an unlit state at predetermined intervals during the inspection of the inspection object.

3. The inspection device according to claim 1 , wherein
the indication unit includes a head mounted display attached to the worker.

4. The inspection device according to claim 1 , further comprising:
an external monitor that displays images captured the wearable camera.
