Abstract

A system and methods to provide imaging service using outdoor lighting networks. The system uses outdoor lighting networks to manage/control video/image sensors connected to the network, e.g. hosted at lighting units, and coordinates the capture of useful video/image data associated with events. The system also provides an information search platform for users to retrieve only the relevant video/image data associated with events of interest. Furthermore, the system controls when and how to retrieve video/image data at lighting units across the whole network according to user requests, the priority of the events, and available bandwidth.

Claims

1. An outdoor lighting network (OLN) comprising:

lighting units equipped with capabilities to communicate with other lighting units in the OLN, said lighting units including,

an imaging device, the imaging device configured to communicate with at least one of the lighting units;

a sensor module, the sensor module configured to communicate sensor data to at least one of the lighting units, wherein the sensor module includes an imaging sensor device or multiple different sensor devices, wherein the sensor data relates to an environmental area of a respective lighting unit; and

a control module configured to record image data from the imaging device of a selected event, only when the selected event is on a list of predetermined selected events that trigger the lighting unit data recording by the imaging device, wherein the selected event is based on sensor data from the sensor module, wherein the control module uses the imaging device data or a combination of multiple different sensor data to identify predetermined events and determine if the identified predetermined events relates to a trigger in the list of predetermined selected events, and assign an event type and a priority to the recorded image data and transmit only the recorded image data of selected events or the selected events of a predetermined priority to a lighting manager, and allow a user to receive portions of the recorded image data of selected events by a different communication method than transmission to the lighting manager.

2. The OLN of claim 1 wherein said sensor module comprises sensor type devices that are selected from the group consisting of occupancy detectors, motion detectors, environmental sensors, alcohol sensors, detectors of signals transmitted from cars, speed detectors, medical alert receivers, temperature sensors, fire alarm signals and combinations thereof.

3. The OLN of claim 1 wherein said different communication method is Wi-Fi.

4. A method to coordinate and control data collection of events from imaging devices controlled through an outdoor lighting network (OLN), said OLN having lighting units and a lighting manager, at least one of the lighting units being in communication with a sensor module wherein the sensor module includes an imaging sensor device or multiple different sensor devices;

the method comprising;

recording image data of a selected event, by one or more of the imaging devices, only when the selected event is is on a list of predetermined selected events that trigger the lighting unit data recoding by the imaging device being detected by the sensor module, and wherein the detection includes using the imaging device data or a combination of multiple sensor data to identify predetermined events and determine if the identified predetermined events relates to a trigger in a list of predetermined events, wherein sensor data from the sensor module relates to an environmental area of a respective lighting unit,

assigning an event type and a priority to the recorded image data and only transmitting the recorded image data of selected events or the selected events of a predetermined priority to the lighting manager, and allow a user to receive portions of the recorded image data of selected events by a different communication method than transmission to the lighting manager.

5. The method of claim 4 wherein the trigger is selected from a group of predefined events consisting of detected movements by a car and/or a pedestrian, smoke detected by a smoke sensor, the presence of alcohol detected by alcohol sensor, detected signals emanating from cars, speed detection, medical alert signals, environmental sensors, temperature sensors, fire alarms, and combinations thereof.

6. The method of claim 4 further comprising the steps of:

processing one or more requests from authorized users to control lighting performance and

controlling lighting performance in accordance with said requests.

7. The method of claim 4 further comprising processing one or more requests from authorized users to record data in emergency situations;

wherein said requests are made in response to an ongoing emergency situation.

8. The method of claim 4 further comprising processing requests to neighboring lighting units to obtain data of an abnormal lighting unit to thereby help in diagnostics.

9. The method of claim 4 further comprising controlling imaging sensors in the sensor module to obtain data with low quality/resolution at certain time instants;

and to obtain data with higher quality upon the detection of a trigger.

10. The method of claim 4 wherein said recording step further comprises a memory management function which in the event the storage device is at or near capacity as new data is being stored, deletes either downloaded or old imaging data according to the assigned priority.

11. The method of claim 4 further comprising:

providing an information platform where users or other systems can search and access the image data and related information pertaining to specific events.

12. The method of claim 11 further comprising enabling a user to search for imaging data based on type of event, time, and location parameters.

13. The method of claim 11 comprising:

generating a user request to the lighting manager based on the user description of the event; and

,

searching by the lighting manager for imaging data in the OLN information database and in the storage devices of one or more lighting units that meets the user request criteria.

14. The method of claim 4 further comprising:

providing by the lighting manager event reports to users based on the image data and related information and according to pre-defined users'"'"' interests; and

,

processing user requests for more detail pertaining to items contained in the event reports.

15. An outdoor lighting network (OLN) comprising:

lighting units equipped with capabilities to communicate with other lighting units in the OLN, said lighting units including,

an imaging device, the imaging device configured to communicate with at least one of the lighting units;

a sensor module, the sensor module configured to communicate sensor data to at least one of the lighting units, wherein the sensor module includes an imaging sensor device or multiple different sensor devices, wherein the sensor data relates to an environmental area of a respective lighting unit; and

a control module configured to record image data from the imaging device of a selected event, only when the selected event is on a list of predetermined selected events that trigger the lighting unit data recording by the imaging device, wherein the selected event is based on sensor data from the sensor module, wherein the control module uses the imaging device data or a combination of multiple different sensor data to identify predetermined events and determine if the identified predetermined events relates to a trigger in the list of predetermined selected events, and assign an event type and a priority to the recorded image data and transmits information about the recorded image data of selected events to a lighting manager, and allow a user to request portions of the recorded image data of selected events.
