Vision based guidance system and method for lawn mowing devices
Vision based guidance system and method for lawn mowing devices are disclosed. An exemplary method for operating an autonomous lawn mower includes receiving, via a receiver, a perimeter data set from a handheld computer. The perimeter data set includes a perimeter outline of at least one perimeter that is determined utilizing a GPS unit of the handheld computer. The exemplary method also includes collecting, via at least one camera, images of a set area within the perimeter outline and mowing, via a mowing blade, grass within the set area. The exemplary method also includes autonomously steering, via a controller, the autonomous lawn mower based on the perimeter outline of the at least one perimeter and the images captured by the at least one camera.
1. A method for operating a lawn mower, the method comprising:
receiving, via a receiver of the lawn mower, directional control inputs of user command signals from a handheld device;
steering, via a controller of the lawn mower, the lawn mower to mow according to the directional control inputs of the user command signals received from the handheld device;
creating a perimeter outline of a mowing area for autonomous control of the lawn mower, via a global positioning system (GPS) unit of the lawn mower, as the lawn mower is controlled according to the directional control inputs of the user command signals received from the handheld device;
collecting, via at least one camera of the lawn mower, images of the mowing area within the perimeter outline;
mowing, by activating a mowing blade of the lawn mower, grass within the mowing area; and
autonomously steering, via the controller, the lawn mower based on the perimeter outline of the mowing area and the images captured by the at least one camera, wherein the step of autonomously steering the lawn mower further includes autonomously steering the lawn mower to follow a mow line between a mowed section and an un-mowed section within the mowing area.
2. A method for operating a lawn mower, the method comprising:
receiving, via a receiver of the lawn mower, directional control inputs of user command signals from a handheld device;
steering, via a controller of the lawn mower, the lawn mower to mow according to the directional control inputs of the user command signals received from the handheld device;
creating a perimeter outline of a mowing area for autonomous control of the lawn mower, via a global positioning system (GPS) unit of the lawn mower, as the lawn mower is controlled according to the directional control inputs of the user command signals received from the handheld device;
collecting, via at least one camera of the lawn mower, images of the mowing area within the perimeter outline;
mowing, via a mowing blade, grass within the mowing area, by:
activating the mowing blade upon identifying, based on the images captured by the at least one camera, that the lawn mower is travelling over an un-mowed section of the mowing area; and
deactivating the mowing blade upon identifying, based on the images captured by the at least one camera, that the lawn mower is travelling over a mowed section of the mowing area; and
autonomously steering, via the controller, the lawn mower based on the perimeter outline of the mowing area and the images captured by the at least one camera.
3. A lawn mower for mowing within an environment, the lawn mower comprising:
a mowing blade;
a global positioning system (GPS) unit configured to a identify a position of the lawn mower;
a receiver configured to receive user command signals that include directional control inputs from a handheld device;
at least one camera configured to collect images of a mowing area; and
a processor configured to:
detect a mow line that separates a mowed section and an un-mowed section within the mowing area based on the images captured by the at least one camera;
activate the mowing blade;
steer the lawn mower to mow according to the directional control inputs of the user command signals received from the handheld device;
create a perimeter outline of the mowing area for autonomous control of the lawn mower using data collected by the GPS unit as the lawn mower is controlled according to the directional control inputs of the user command signals received from the handheld device; and
autonomously steer the lawn mower based on the perimeter outline of the mowing area and the images captured by the at least one camera, wherein, to autonomously steer the lawn mower, the processor is configured to steer the lawn mower to follow the mow line that separates the mowed section and the un-mowed section.
