Abstract

A method and a system for road monitoring, comprises the steps of receiving, via a communication module, a first point cloud data from one or more designated road side units (RSUs) from one or more of a plurality of RSUs located in a defined geographical area; receiving, via the communication module, a second point cloud data from one or more designated vehicle on-board data processing units of vehicles located in the defined geographical area; processing, via a processing module, the first point cloud data and the second point cloud data to generate a processed point cloud data; and transmitting, via the communication module, information derived from the processed point cloud data to one or more of the RSUs and/or the vehicle on-board data processing units of vehicles located in the defined geographical area.

Claims (26)

1 . A method for detecting blind areas for vehicles in a traffic environment of a defined geographical area, comprising:

receiving, via a communication module of a Vehicle-to-Everything (V2X) system, a first point cloud data from one or more designated road-side units (RSUs) located in the defined geographical area;

processing, via a processing module of the V2X system, at least the received first point cloud data to identify any potential blind areas in the traffic environment;

in response to a request from the communication module to one or more designated vehicle on-board data processing units of vehicles located in the defined geographical area, receiving, via the communication module, a second point cloud data from said one or more designated vehicle on-board data processing units;

processing, via the processing module, the first point cloud data and the second point cloud data by comparing said data to generate merged data comprising a processed point cloud data representing a global view of the traffic environment in the defined geographical area including view information for the detected blind areas; and

transmitting, via the communication module, information derived from the processed point cloud data to one or more of the vehicle on-board data processing units of vehicles located in the defined geographical area to provide the view information for the detected blind areas.

2 . The method according to claim 1 , wherein the step of receiving a first point cloud data from one or more designated RSUs further comprises extracting a dynamic first point cloud data from the first point cloud data, and comparing and/or merging the extracted dynamic first point cloud data with a static point cloud data previously stored in a memory prior to the processing step.

3 . The method according to claim 1 , further comprising a step of partitioning the processed point cloud data into a plurality of point cloud data partitions or subsections prior to the transmitting step.

4 . The method according to claim 3 , wherein the transmitting step comprises transmitting information derived from one or more selected point cloud data partitions to one or more of the RSUs and/or the vehicle on-board data processing units located in the defined geographical area.

5 . The method according to claim 1 , wherein the step of receiving a first point cloud data comprises receiving point cloud data in relation to at least a section of the defined geographical area from the one or more designated RSUs located in the defined geographical area.

6 . The method according to claim 5 , wherein the at least a section of the defined geographical area comprises a plurality of non-overlapping subsections of the defined geographical area.

7 . The method according to claim 1 , wherein the step of receiving a second point cloud data comprises receiving point cloud data in relation to at least a section of the defined geographical area from the one or more designated vehicle on-board data processing units of vehicles located in the defined geographical area.

8 . The method according to claim 7 , wherein the at least a section of the defined geographical area comprises a plurality of non-overlapping subsections of the defined geographical area.

9 . The method according to claim 7 , wherein the vehicle on-board data processing units of vehicles located in the defined geographical area are designated based on rate of data transmission and/or distance from the communication module.

10 . The method according to claim 1 , wherein the information derived from the processed point cloud data transmitted via the transmitting step to the one or more vehicle on-board data processing units comprises information relating to one or more blind areas of the one or more RSUs and/or the vehicle on-board data processing units.

11 . A Vehicle-to-Everything (V2X) system for detecting blind areas for vehicles in a traffic environment of a defined geographical area, the system comprising:

a communication module of the V2X system configured to receive a first point cloud data from one or more designated road-side units (RSUs) located in the defined geographical area; and

a processing module of the V2X system configured to process at least the received first point cloud data to identify any potential blind areas in the traffic environment;

wherein the communication module is configured to receive, in response to a request from the communication module to one or more designated vehicle on-board data processing units of vehicles located in the defined geographical area, a second point cloud data from said one or more designated vehicle on-board data processing units; and

wherein the processing module is configured to process the received first point cloud data and second point cloud data by comparing said data to generate merged data comprising a processed point cloud data representing a global view of the traffic environment in the defined geographical area including view information for the detected blind areas;

wherein the communication module is configured to transmit information derived from the processed point cloud data to one or more of the vehicle on-board data processing units of vehicles located in the defined geographical area to provide the view information for the detected blind areas.

12 . The system according to claim 11 , wherein the communication module is configured to receive and transmit point cloud data and information derived from point cloud data from and to one or more of the RSUs and/or the vehicle on-board data processing units of vehicles located in the defined geographical area via one or more cellular vehicle-to-every (C-V2X) communication networks.

13 . The system according to claim 11 , wherein the receiving module is configured to extract a dynamic first point cloud data from the first point cloud data, and compare and/or merge the extracted dynamic first point cloud data with a static point cloud data previously stored in a memory prior processing by the processing module.

14 . The system according to claim 11 , wherein the processing module is configured to partition the processed point cloud data into a plurality of point cloud data partitions, and to assign one or more point cloud data partitions for transmission.

15 . The system according to claim 14 , wherein the plurality of point cloud data partitions correspond to a plurality of non-overlapping subsections of the defined geographical area.

16 . The system according to claim 15 , wherein the plurality of non-overlapping subsections correlate to one or more blind areas of the one or more RSUs and/or the vehicle on-board data processing units of vehicles located in the defined geographical area.
