Abstract
Methods and systems for monitoring blockages of emergency escape routes and emergency exits of a building include capturing a plurality of images which may correspond to an emergency escape route and/or an emergency exit of a building. The plurality of images may be analyzed to determine when a stationary object is present and at least partially blocking the emergency escape route and/or the emergency exit. If a blockage is detected, a user may be notified of the blockage.
Claims18
A method for monitoring for blockages of emergency escape routes of a building, comprising:
- capturing a plurality of images each corresponding to a corresponding one of a plurality of escape route segments along a predefined emergency escape route of a building;
- analyzing the plurality of images to determine when a stationary object is present and at least partially blocks at least one of the plurality of escape route segments, wherein determining that a stationary object at least partially blocks at least one of the plurality of escape route segments comprises:
- computing a blockage parameter that represents a severity of a blockage of the corresponding escape route segment;
- comparing the blockage parameter to a blockage threshold, wherein the blockage threshold corresponds to a locally applicable safety code;
- and
- when it is determined that a stationary object is present and at least partially blocks at least one of the plurality of escape route segments, notifying a user of a blockage.
A method for notifying a user of a blockage of an emergency exit of a building, the method comprising:
- receiving and displaying a notification on a user's mobile device notifying the user of a detected blockage of an emergency exit of a building;
- displaying an image of the blockage on the user's mobile device;
- and
- providing a link on the user's mobile device for contacting personnel of the building responsible for mitigating the blockage.
A method for monitoring for a blockage of at least part of an emergency escape route of a building, comprising:
- capturing stereoscopic images of at least part of the emergency escape route of the building;
- analyzing the stereoscopic images to determine when a stationary object is present and at least partially blocks the at least part of the emergency escape route of the building;
- when it is determined that the stationary object is present and at least partially blocks the at least part of the emergency escape route:
- determining a severity of the blockage;
- notifying a user of the blockage;
- and
- notifying the user of the determined severity of the blockage.
