Abstract

A monitoring system for a periphery of a structure (100) comprises a monitoring module (102) having a detection and ranging system (304, 308) arranged to support monitoring of a portion of the periphery in order to detect passage of a body beyond the periphery. The detector (304, 308) has an imaging resolution that prevents conclusive visual identification by a human operator of the nature of the body. The monitoring module also comprises a video capture apparatus (312, 314) arranged to provide video data. The system also comprises a monitoring station apparatus (200) arranged to receive data from the monitoring module (102). In response to detection of the passage of the body by the detection system (304, 308), the monitoring station (200) enables the operator to review the video data. The video data enables the operator to identify readily the nature of the body detected and thereby to provide confirmatory visual evidence when the body is human.

Claims

1. A monitoring system for a periphery of a structure, the system comprising:

a monitoring module comprising;

a detection system arranged to support monitoring of a portion of the periphery corresponding to a coverage field in order to detect, when in use, passage of a body beyond the periphery, the detection system having an imaging resolution that prevents conclusive visual identification by a human operator of the nature of the body;

a video capture apparatus arranged to provide video data in respect of the coverage field; and

a monitoring station apparatus arranged to receive data from the monitoring module and in response to detection of the passage of the body by the detection system to enable review of the video data by the human operator, the video data enabling the human operator to identify readily the nature of the body detected and thereby to provide confirmatory visual evidence when the body is human.

2. The system according to claim 1, wherein the detection system is arranged to support monitoring of a portion of a volume with respect to the structure in order to detect, when in use, passage of the body across at least part of the portion of the volume.

3. The system according to claim 2, wherein the volume envelops the vessel.

4. The system according to claim 1, wherein the monitoring module comprises a local processing resource arranged to support detection of the passage of the body and to communicate detection of the passage of the body to the monitoring station apparatus.

5. The system according to claim 4, wherein the video capture apparatus and the local processing resource are arranged to cooperate in order to store the video data and to communicate the video data to the monitoring station apparatus in response to detection of the passage of the body by the detection system.

6. The system according to claim 1, wherein the video data is buffered and relates to a period of time in respect of the passage of the body across the at least part of the portion of the volume.

7. The system according to claim 6, when dependent upon claim 5, wherein the video capture apparatus is arranged to buffer captured video, the video being stored as the video data.

8. The system according to claim 1, further comprising:

a wired or wireless communications network arranged to support communications between the monitoring module and the monitoring station apparatus.

9. The system according to claim 1, further comprising:

a signal processing module arranged to analyse data generated by the detection system in order to detect the passage of the body across the at least part of the portion of the volume.

10. The system according to claim 9, wherein the signal processing module is arranged to detect a track pattern corresponding to the passage of the body.

11. The system according to claim 1, wherein the detection system is a wireless object detector arranged to detect an echo from a transmitted probe signal.

12. The system according to claim 1, wherein the detection system comprises a radar detector module.

13. The system according to claim 1, further comprising:

a trajectory determination module arranged to analyse the passage of the body and to identify a location within the monitored volume from which the passage of the body started.

14. The system according to claim 1, wherein the passage of the body across the at least part of the portion of the volume is a falling body.

15. The system according to claim 1, wherein the passage of the body across the at least part of the portion of the volume is a climbing body.

16. The system according to claim 1, wherein the monitoring station apparatus is arranged to receive location data and to determine a location at which the passage of the body was detected.

17. The system according to claim 1, further comprising:

a water current monitoring apparatus;

wherein

the monitoring station apparatus is operably coupled to the water current monitoring apparatus and arranged to obtain an indication of a prevailing water current when the passage of the body was detected.

18. The system according to claim 1, wherein the monitoring station apparatus is arranged to record a time at which the passage of the body is detected and/or the monitoring module is arranged to record a time at which the passage of the body is detected.

19. The system according to claim 1, wherein the monitoring module is arranged to generate an alert message in response to detection of the passage of the body.

20. The system according to claim 1, wherein the monitoring station apparatus provides a video playback capability to review the video data at least in respect of the period of time in respect of the detection of the passage of the body.

21. The system according to claim 1, wherein the detection system is a wireless object detector.

22. The system according to claim 1, wherein the detection system is a detection and ranging system.

23. A sea-faring vessel comprising the monitoring system according to claim 1.

24. The vessel according to claim 23, further comprising:

a plurality of monitoring modules; and

the plurality of monitoring modules serving, when in use, to support monitoring of the periphery of the vessel.

25. A method of monitoring a periphery of a structure, the method comprising:

monitoring a portion of the periphery correspond to a coverage field using a detection system in order to detect passage of a body beyond the periphery, the monitoring using an imaging resolution that prevents conclusive visual identification by a human operator of the nature of the body;

capturing video as video data in respect of the coverage field; and

in response to detection of the passage of the body as a result of the monitoring enabling review of the video data by the human operator, the video data enabling the human operator to visually identify readily the nature of the body detected and thereby to provide confirmatory visual evidence when the body is human.

26. A monitoring module apparatus comprising:

a detection system arranged to support monitoring of a portion of a periphery corresponding to a coverage field in order to detect, when in use, passage of a body beyond the periphery, the system having an imaging resolution that prevents conclusive visual identification by a human operator of the nature of the body; and

a video capture apparatus arranged to provide video data in respect of the coverage field.
