Abstract
Systems and methods may be used to map an environment visible in an image captured by a camera. The mapping may include a floor map (e.g., locations within the environment where a floor is present). A method may include receiving images from a camera. The method may include using an object that moved from a first image to a second image to identify floor points within the environment. The method may include mapping a floor plane of the environment using the floor points.
Claims20
A device for mapping an environment observable via a camera, the device comprising:
- a processor;
- and
- memory, communicatively coupled to the processor, the memory including instructions, which when executed, cause the processor to:
- receive a series of frames of video data captured by the camera;
- identify a person within the series of frames;
- based on a determined skeletal structure for the person in each of the series of frames, calculate a primary axis of the person, the primary axis including a foot endpoint;
- and
- map a 3D floor plane of an area captured in the series of frames based on identified locations of the foot endpoint in each of the series of frames.
A method for mapping an environment observable via a camera, the method comprising:
- receive, at a processor, a series of frames of video data captured by a camera;
- identify, using the processor, a person within the series of frames;
- based on a determined skeletal structure for the person in each of the series of frames, calculate a primary axis of the person, the primary axis including a foot endpoint;
- generating, using the processor, a map of a 3D floor plane of an area captured in the series of frames based on identified locations of the foot endpoint in each of the series of frames;
- and
- outputting the map.
An apparatus for mapping an environment observable via a camera, the apparatus comprising:
- means for receiving a series of frames of video data captured by a camera;
- means for identifying a person within the series of frames;
- means for, based on a determined skeletal structure for the person in each of the series of frames, calculating a primary axis of the person, the primary axis including a foot endpoint;
- means for mapping a 3D floor plane of an area captured in the series of frames based on identified locations of the foot endpoint in each of the series of frames;
- and
- means for outputting the 3D floor plane for display.
