Maintaining heatmaps using tagged visual data
First Claim
1. A method for generating map data, the method comprising:
- receiving visual data captured by a camera coupled to a device, wherein the visual data is tagged with source identifying information associated with a wireless access point other than the device by including the source identifying information in metadata attached to the visual data, wherein the metadata describes attributes associated with the visual data;
acquiring the source identifying information associated with the wireless access point from the metadata attached to the visual data;
identifying at least one visual feature from the visual data;
determining a coordinate on a map at which the visual data was acquired based on identifying the at least one visual feature from the visual data; and
associating the coordinate on the map with the source identifying information associated with the wireless access point acquired from the metadata attached to the visual data.

Abstract
Techniques describe tagging visual data (e.g., image and/or video data) with wireless and sensor measurement information by a mobile device. Tagged visual data may be sent to a server, such as a crowdsourcing server. Techniques further describe receiving visual data from a device, wherein the visual data is tagged with information comprising source identifying information associated with an at least one signal emitting device, identifying at least one visual feature from the visual data, determining a coordinate on a map at which the visual data was acquired based on identifying the at least one visual feature from the visual data, and associating the coordinate on the map with the information associated with the at least one signal emitting device.

12. A server computing device comprising:
-
a transceiver configured to receive visual data captured by a camera coupled to a device, wherein the visual data is tagged with source identifying information associated with a wireless access point other than the device by including the source identifying information in metadata attached to the visual data, wherein the metadata describes attributes associated with the visual data; a memory configured to store the visual data and the metadata; one or more processors configured to; acquire the source identifying information associated with the wireless access point from the metadata attached to the visual data; identify at least one visual feature from the visual data; determine a coordinate on a map at which the visual data was acquired based on identifying the at least one visual feature from the visual data; and associate the coordinate on the map with the source identifying information associated with the wireless access point acquired from the metadata attached to the visual data. - View Dependent Claims (13, 14, 15, 16)
