Abstract

According to one embodiment, an analysis device performs an analysis related to a plurality of tasks of a manufacturing process. The analysis device receives an image when each of the plurality of tasks is performed. The analysis device receives the images from an imaging device acquiring the images. The analysis device receives a detection signal from a tool used in at least one of the plurality of tasks. The detection signal is detected by the tool. The analysis device refers to end determination data for determining an end of each of the plurality of tasks. The analysis device determines the end of each of the plurality of tasks based on the images, the detection signal, and the end determination data.

First claim

What is claimed is:

1. An analysis device performing an analysis related to a plurality of tasks of a manufacturing process, the analysis device comprising circuitry configured to
receive an image when each of the plurality of tasks is performed,
extract a skeleton of a human body from the image,
receive a detection signal detected by a tool used in at least one of the plurality of tasks,
determine a start of each of the plurality of tasks when the extracted skeleton touches a first object, and
determine an end of each of the plurality of tasks based on the images, the detection signal, and end determination data for determining an end of each of the plurality of tasks.

2. The analysis device according to claim 1 , wherein
the circuitry is configured to cause an output device to output a work instruction related to one of the plurality of tasks when the one of the plurality of tasks is performed.

3. The analysis device according to claim 1 , wherein
the circuitry is configured to calculate man-hours of each of the plurality of tasks based on a determination result of the start and the end of each of the plurality of tasks.

4. The analysis device according to claim 3 , wherein the circuitry is configured to
refer to a cost model of a relationship between man-hours and cost for each of the plurality of tasks, and
calculate a cost of the plurality of tasks based on the cost model and the calculated plurality of man-hours.

5. The analysis device according to claim 1 , wherein
the tool includes at least one selected from the group consisting of a torque sensor, an acceleration sensor, and an angular velocity sensor.

6. The analysis device according to claim 1 , wherein the circuitry is configured to
refer to a check sheet for checking the end of each of the plurality of tasks, and
mark a check in the check sheet according to the determination of the end of each of the plurality of tasks.

7. The analysis device according to claim 1 , wherein the circuitry is configured to
refer to instruction data of a work instruction of at least one of the plurality of tasks, and
use the images, the detection signal, and the instruction data to determine whether or not a task performed in the at least one of the plurality of tasks matches the work instruction.

8. The analysis device according to claim 1 , wherein
the circuitry is configured to determine an interruption of at least one of the plurality of tasks when the skeleton is not extracted from the image for a prescribed period or when the detection signal is not transmitted from the tool the prescribed period.

9. An analysis system, comprising:
the analysis device according to claim 1 ;
the imaging device; and
the tool.

10. An analysis method causing a computer to perform an analysis related to a plurality of tasks of a manufacturing process,
the analysis method causing the computer to:
receive an image when each of the plurality of tasks is being performed;
extract a skeleton of a human body from the image;
receive a detection signal detected by a tool used in at least one of the plurality of tasks;
determine a start of each of the plurality of tasks when the extracted skeleton touches a first object; and
determine an end of each of the plurality of tasks based on the images, the detection signal, and end determination data for determining an end of each of the plurality of tasks.

11. A non-transitory computer-readable storage medium storing a program for executing the analysis method according to claim 10 .
