Abstract

A surveillance system for monitoring mental concentration of a worker, capable of being installed in a control room, includes:

an image capture device for capturing eye images of the worker;

an inspection unit coupled to the image capture device for inspecting motion status of an eye of the worker and calculating positions of a screen where the eye stares; and

an analysis unit coupled to the inspection unit and configured to analyze the calculated position information transferred from the inspection unit in order to identify the mental concentration and quality of the worker.

Claims

1. A surveillance system for monitoring mental concentration of a worker, comprising:

an image capture device configured to capture eye images of the worker;

an inspection unit coupled to the image capture device for inspecting motion status of an eye of the worker and calculating positions of a screen where the eye stares; and

an analysis unit coupled to the inspection unit and configured to analyze the calculated position information transferred from the inspection unit in order to identify the mental concentration and quality of the worker.

2. The surveillance system of claim 1 wherein the image capture device is a CCD (Charged Coupled Device) camera.

3. The surveillance system of claim 1 wherein the inspection unit identifies the pupil of the eye from the continuous captured eye images.

4. The surveillance system of claim 1 wherein the inspection unit analyzes the images and calculates position and size of the pupil.

5. The surveillance system of claim 1 wherein the inspection unit evaluates a region surrounding the pupil shown in the eye image to detect position of the eye as well as gaze direction of the eye.

6. The surveillance system of claim 1 wherein the analysis unit calculates the extent and density of observation on each section of the multi-split screen.

7. The surveillance system of claim 1 wherein the analysis unit is capable of sending out a warning to fulfill the surveillance function.

8. The surveillance system of claim 1 wherein the analysis unit is capable of recording history analysis of the monitoring condition.
