Abstract
A surroundings monitoring system includes: a detection device that is disposed in a work vehicle and configured to be able to detect an object around the work vehicle; an acquisition unit that acquires a command signal indicating an operation checking mode for inspecting the detection device; a determining unit that determines a quality of an operating state of the detection device based on a detection result of the detection device after the command signal is acquired; and a display device that displays identification information of the detection device of which the operating state is determined to be not good by the determining unit.
Claims15
A surroundings monitoring system comprising:
- an image capturing device mounted on a work vehicle so as to image an area around the work vehicle;
- radar devices mounted on the work vehicle so as to detect different areas around the work vehicle respectively, and configured to detect an object around the work vehicle when the object is within detection areas thereof;
- a mode control unit configured to switch mode of the work vehicle to an operation checking mode for determining whether or not the radar devices can detect an object used for checking of operation, when the object is within the detection areas of the radar devices;
- a determining unit configured to determine that an operating state of a radar device is good when the radar device can detect the object within the detection area thereof, and that an operating state of a radar device is not good when the radar device cannot detect the object within the detection area thereof, among the radar devices in the operation checking mode;
- and
- a display device configured to display the work vehicle, and a bird's-eye image around the work vehicle generated based on an image captured by the image capturing device, on a screen thereof,
- wherein the display device is configured to continue to display the detection area of the radar device of which the operating state is not good, so as to be distinguishable from the detection area of the radar device of which the operating state is good, on the bird's-eye image, during the operation checking mode.
A surroundings monitoring method comprising:
- imaging an area around a work vehicle by an image capturing device mounted on the work vehicle;
- detecting an object within detection areas of radar devices mounted on the work vehicle so as to detect different areas around the work vehicle respectively;
- switching mode of the work vehicle to an operation checking mode for determining whether or not the radar devices can detect an object used for checking of operation, when the object is within the detection areas of the radar devices;
- determining that an operating state of a radar device is good when the radar device can detect the object within the detection area thereof, and that an operating state of a radar device is not good when the radar device cannot detect the object within the detection area thereof, among the radar devices in the operation checking mode;
- and
- displaying the work vehicle, and a bird's-eye image around the work vehicle generated based on an image captured by the image capturing device, on a screen of a display device;
- and
- continuing to display the detection area of the radar device of which the operating state is not good, so as to be distinguishable from the detection area of the radar device of which the operating state is good, on the bird's-eye image, during the operation checking mode.
