Abstract

A workflow evaluation system includes (i) a camera located at a facility, the camera positioned to record video data of multiple instances of a procedure involving an action performed on a workpiece, the action involving a physical movement; (ii) a database storing at least one workflow rule concerning the procedure, at least one of the workflow rules involving the physical movement of the action performed on the workpiece; and (iii) a procedure monitoring processor communicatively coupled to the database and configured to access the at least one workflow rule involving the physical movement of the action performed on the workpiece, compare corresponding physical movement information obtained from the video data of one of the multiple instances of the procedure to the accessed at least one workflow rule, and send a non-satisfy message if the compared corresponding physical movement information does not satisfy the accessed at least one workflow rule.

Claims

1. A workflow evaluation system comprising:

a camera located at a facility, the camera positioned to record video data of multiple instances of a procedure involving an action performed on a workpiece at the facility, the action involving a physical movement;

a database storing at least one workflow rule concerning the procedure, at least one of the workflow rules involving the physical movement of the action performed on the workpiece; and

a procedure monitoring processor communicatively coupled to the database and configured to

access the at least one workflow rule involving the physical movement of the action performed on the workpiece,

compare corresponding physical movement information obtained from the video data of one of the multiple instances of the procedure to the accessed at least one workflow rule, and

send a non-satisfy message if the compared corresponding physical movement information does not satisfy the accessed at least one workflow rule.

2. The workflow evaluation system of claim 1, which includes a depth sensor configured to record depth data regarding the action performed on the workpiece, and wherein the corresponding physical movement information is obtained from the video data and the depth data.

3. The workflow evaluation system of claim 2, wherein a three-dimensional representation of the video data is created using the distance data and a shading of pixels within the video data, and wherein the corresponding physical movement information is obtained from the three-dimensional representation.

4. The workflow evaluation system of claim 1, which further includes a microphone recording audio data, and wherein the procedure monitoring processor uses the audio data in combination with the video data.

5. The workflow evaluation system of claim 1, wherein the database stores at least one additional workflow rule specifying a minimum or maximum duration regarding the action performed on the workpiece, and wherein the procedure monitoring processor is further configured to (i) access the at least one workflow rule specifying the minimum or maximum duration and (ii) compare corresponding action duration information obtained from the video data of the instance of the procedure to the accessed at least one minimum or maximum duration rule.

6. The workflow evaluation system of claim 5, wherein the procedure monitoring processor is further configured to send a non-satisfy message if the compared corresponding action duration information does not satisfy the accessed at least one minimum or maximum duration rule.

7. The workflow evaluation system of claim 6, wherein the non-satisfy message for the minimum or maximum duration rule is different than the non-satisfy message for the physical movement rule.

8. The workflow evaluation system of claim 5, further comprising a statistical processor configured to create at least one of the minimum or maximum duration rule or the physical movement rule prior to the use of the minimum or maximum duration rule or the physical movement rule, respectively, by the inspection monitoring processor, the creation of the minimum or maximum duration rule or the physical movement rule based on at least one of a regulatory specification, common know-how, best practices, or a statistical analysis of previously collected video data.

9. The workflow evaluation system of claim 1, wherein the procedure monitoring processor is further configured to repeat the accessing, comparing, and sending if needed for each of the multiple instances of the procedure involving the action performed on the workpiece at the facility.

10. The workflow evaluation system of claim 9, wherein each instance of the procedure involves a different workpiece.

11. The workflow evaluation system of claim 9, wherein at least two instances of the procedure involve the same workpiece.

12. The workflow evaluation system of claim 1, which is configured to prevent a next instance of the procedure involving the action performed on the workpiece until the at least one workflow rule for the current procedure is satisfied.

13. The workflow evaluation system of claim 1, wherein the workpiece is an automobile and the action involves an inspection action performed by an inspector on the vehicle.

14. The workflow evaluation system of claim 1, wherein the workpiece is a medical procedure and the action involves an inventory of surgical equipment used with the medical procedure.

15. The workflow evaluation system of claim 1, wherein the at least one workflow rule involving the physical movement of the action performed on the workpiece concerns movement of a tool applied to or utilized in the workpiece.

16. The workflow evaluation system of claim 1, wherein the at least one workflow rule involving the physical movement of the action performed on the workpiece concerns movement of a worker relative to the workpiece.

17. The workflow evaluation system of claim 1, wherein the at least one workflow rule is formed via feedback from prior video data obtained from the camera.

18. A workflow evaluation system comprising:

a camera located at a facility, the camera positioned to record video data of multiple instances of a procedure involving an action performed on a workpiece at the facility;

a database storing at least one workflow rule concerning the procedure, at least one of the workflow rules involving a minimum or maximum duration regarding the action performed on the workpiece; and
