Method, apparatus, and system for location sharing using a LiDAR-based location signature
An approach is provided for location sharing using a LiDAR-based location signature. The approach involves, for example, receiving a Light Detection and Ranging (LiDAR) scan of a location captured by a LiDAR sensor of a portable device. The approach also involves processing the LiDAR scan to generate a LiDAR location signature that is representative of the location of the portable device. The approach further involves transmitting the LiDAR location signature to another device to share the location of the portable device with the another device.
1. A computer-implemented method comprising:
receiving, by one or more processors, a Light Detection and Ranging (LiDAR) scan of a location captured by a LiDAR sensor of a portable device;
processing the LiDAR scan to generate a LiDAR location signature that is representative of the location of the portable device, wherein the LiDAR scan is a point cloud and the LiDAR location signature includes a feature extracted from the point cloud, a subsampling of the point cloud, a crop of the point cloud, or a combination thereof; and
transmitting the LiDAR location signature to another device to share the location of the portable device with the another device.
2. The method of claim 1 , wherein the another device compares the LiDAR location signature to a reference LiDAR location signature to determine the shared location of the portable device.
3. The method of claim 2 , wherein the reference LiDAR location signature is generated by crowdsourcing, a cloud device, an edge device, the another device, or a combination thereof.
4. The method of claim 1 , wherein the another device captures a subsequent LiDAR scan of an environment in a given area until a subsequent LiDAR location signature generated from the subsequent LiDAR scan matches the LiDAR location signature of the portable device within a threshold matching criterion.
5. The method of claim 1 , further comprising:
generating a user interface that presents a scanning parameter for initiating the capturing of the LiDAR scan; and
presenting the user interface on the portable device.
6. The method of claim 5 , wherein the scanning parameter includes a scanning duration, a scanning direction, a scanning orientation, or a combination thereof.
7. The method of claim 1 , further comprising:
capturing additional sensor data representing an attribute of an environment of the location; and
associating the additional sensor data, information determined from the additional sensor data, or a combination thereof with the LiDAR location signature.
8. The method of claim 7 , wherein the additional sensor data includes hyperspectral data, and wherein the method further comprises:
processing the hyperspectral data to determine information about a material of an object located in the environment of the location.
9. The method of claim 1 , wherein the LiDAR location signature is used to indicate a meeting location, a delivery location, a parking location, a location that is to be avoided, or a combination thereof.
10. The method of claim 1 , wherein the LiDAR location signature includes a point cloud representing at least a portion of the environment of the location.
11. An apparatus comprising:
at least one processor; and
at least one memory including computer program code for one or more programs,
the at least one memory and the computer program code configured to, within the at least one processor, cause the apparatus to perform at least the following,
receiving, by one or more processors, a Light Detection and Ranging (LiDAR) scan of a location captured by a LiDAR sensor of a portable device;
processing the LiDAR scan to generate a LiDAR location signature that is representative of the location of the portable device, wherein the LiDAR scan is a point cloud and the LiDAR location signature includes a feature extracted from the point cloud, a subsampling of the point cloud, a crop of the point cloud, or a combination thereof; and
transmitting the LiDAR location signature to another device to share the location of the portable device with the another device.
12. The apparatus of claim 11 , wherein the another device compares the LiDAR location signature to a reference LiDAR location signature to determine the shared location of the portable device.
13. The apparatus of claim 12 , wherein the reference LiDAR location signature is generated by crowdsourcing, a cloud device, an edge device, the another device, or a combination thereof.
14. The apparatus of claim 11 , wherein the another device captures a subsequent LiDAR scan of an environment in a given area until a subsequent LiDAR location signature generated from the subsequent LiDAR scan matches the LiDAR location signature of the portable device within a threshold matching criterion.
15. The apparatus of claim 11 , further comprising:
generating a user interface that presents a scanning parameter for initiating the capturing of the LiDAR scan; and
presenting the user interface on the portable device.
16. A non-transitory computer-readable storage medium carrying one or more sequences of one or more instructions which, when executed by one or more processors, cause an apparatus to perform:
receiving, by one or more processors, a Light Detection and Ranging (LiDAR) scan of a location captured by a LiDAR sensor of a portable device;
processing the LiDAR scan to generate a LiDAR location signature that is representative of the location of the portable device, wherein the LiDAR scan is a point cloud and the LiDAR location signature includes a feature extracted from the point cloud, a subsampling of the point cloud, a crop of the point cloud, or a combination thereof; and
transmitting the LiDAR location signature to another device to share the location of the portable device with the another device.
17. The non-transitory computer-readable storage medium of claim 16 , wherein the another device compares the LiDAR location signature to a reference LiDAR location signature to determine the shared location of the portable device.
18. The non-transitory computer-readable storage medium of claim 17 , wherein the reference LiDAR location signature is generated by crowdsourcing, a cloud device, an edge device, the another device, or a combination thereof.
19. The non-transitory computer-readable storage medium of claim 16 , wherein the another device captures a subsequent LiDAR scan of an environment in a given area until a subsequent LiDAR location signature generated from the subsequent LiDAR scan matches the LiDAR location signature of the portable device within a threshold matching criterion.
20. The non-transitory computer-readable storage medium of claim 16 , further comprising:
generating a user interface that presents a scanning parameter for initiating the capturing of the LiDAR scan; and
presenting the user interface on the portable device.
