Claim 0:
1. A remote operation terminal that is portable by an operator and is used for remotely operating a work apparatus of a work vehicle, the remote operation terminal comprising:
a terminal-side communication device configured to communicate with a communication device of the work vehicle;
a terminal-side manipulation tool configured to input a movement direction and a movement speed of the work apparatus via a manipulation direction and a manipulation amount;
a terminal-side azimuth sensor configured to detect geomagnetism and calculate an azimuth around a housing in a state in which an operation panel of the housing of the remote operation terminal faces upward;
a terminal-side control apparatus configured to calculate a vector that represents the movement direction and the movement speed of the work apparatus in accordance with the manipulation direction and the manipulation amount of the terminal-side manipulation tool; and
a terminal-side display apparatus that is provided on the operation panel of the housing of the remote operation terminal and is configured to display an image in which a directed line segment that represents the vector is superimposed on an image taken by a camera of the work vehicle,
wherein the terminal-side display apparatus is configured to
make a first azimuth and a second azimuth corresponding to each other, the first azimuth being an azimuth of the operation panel of the housing and indicated by the terminal-side azimuth sensor and the second azimuth being an azimuth in an image taken by the camera and indicated by a vehicle-side azimuth sensor provided to the work vehicle, and
rotate the image taken by the camera in a displayed image such that a direction in the image coincides with a direction of the operation panel of the housing.
