1. A work vehicle comprising:
- a vehicle body;
cameras provided on the vehicle body, each of cameras being configured to capture images of each of detection areas around the work vehicle;
obstruction detection sensors provided on the vehicle body to detect an obstruction with respect to the work vehicle;
at least one monitor provided in the vehicle body to display at least one monitor display image;
a memory to store a map defining a work field in which the work vehicle is to work; and
circuitry configured tocalculate a vehicle position of the work vehicle based on satellite positioning data,determine whether the obstruction detected by the obstruction detection sensors is inside the work field based on the map;
determine a focused area in which the obstruction is detected among the detection areas if the obstruction is determined to be inside the work field,determine a prioritized display image among the images captured by the cameras, the prioritized display image including the focused area,generate an overhead image showing the work vehicle and a peripheral area around the work vehicle by view-point converting the images captured by the cameras and compositing the images which have been view-point converted, andgenerate the at least one monitor display image including a first display area in which the overhead image is displayed and a second display area in which the prioritized display image is displayed.

Abstract
A work vehicle includes circuitry configured to determine a focused area based on signals detected by work and travel situation detection sensors. The circuitry is configured to determine a prioritized display image among images captured by cameras, the prioritized display image including the focused area. The circuitry is configured to compose the images captured by the cameras by view-point converting the images to generate an overhead image around the vehicle body. The circuitry is configured to generate at least one monitor display image including a first display area in which the overhead image is displayed and a second display area in which the prioritized display image is displayed.

6. A work vehicle comprising:
-
a vehicle body having a base direction; a work apparatus movably mounted to the vehicle body to be in contact with and apart from a work field that the work vehicle is to work, an orientation of the work apparatus with respect to the vehicle body being changeable in accordance with a height of the work vehicle with respect to the work field; cameras provided on the vehicle body, each of the cameras being configured to capture images of each of detection areas around the work vehicle, the cameras including a work apparatus camera having an optical axis and rotatably mounted on the work apparatus such that the optical axis of the work apparatus camera is controlled to be substantially parallel to the base direction regardless of the orientation of the work apparatus with respect to the vehicle body; obstruction detection sensors provided on the vehicle body to detect an obstacle around the vehicle body; at least one monitor provided in the vehicle body to display at least one monitor display image; and circuitry configured to determine a focused area in which the obstruction is detected among the detection areas, determine a prioritized display image among the images captured by the cameras, the prioritized display image including the focused area, generate an overhead image showing the work vehicle and a peripheral area around the work vehicle by view-point converting the images captured by the cameras and compositing the images which have been view-point converted, and generate the at least one monitor display image including a first display area in which the overhead image is displayed and a second display area in which the prioritized display image is displayed. - View Dependent Claims (7)

9. An image displaying method for a work vehicle, comprising:
-
capturing vehicle surrounding images of detection areas around a vehicle body of the work vehicle, respectively; detecting an obstruction with respect to the work vehicle; calculating a vehicle position of the work vehicle based on satellite positioning data, determining whether the obstruction detected is inside a work field in which the work vehicle is to work based on a map defining the work field, determining a focused area in which the obstruction is detected among the detection areas if the obstruction is determined to be inside the work field; determining a prioritized display image among the vehicle surrounding images, the prioritized display image including the focused area; generate an overhead image showing the work vehicle and a peripheral area around the work vehicle by view-point converting the vehicle surrounding images and compositing the vehicle surrounding images which have been view-point converted; and generating at least one monitor display image including a first display area in which the overhead image is displayed and a second display area in which the prioritized display image is displayed; and displaying the at least one monitor display image in at least one monitor.
