REMOTE CONTROL DEVICE AND REMOTE CONTROL SYSTEM

WIPO Patent Application WO/2021/124858

A1

Provided are a remote control device and a remote control system which make it possible to reduce or resolve deviation of the position of an indicator image, such as a line drawing, of a working part in an image, with respect to the position of the working part in real space. An indicator image Img2 is generated in a remote control device 20, and is then superimposed on a working environment image Img1 and outputted to an image output device 221. Due to transmission lag of captured image data, or due to causes such as communication failure between the remote control device 20 and a work machine 40, the position and attitude coordinate values of the working part according to the captured image data in the working environment image may change discontinuously, and thus may deviate from the position and attitude coordinate values of the working part estimated according to an operation mode of a remote control mechanism 211. In this case, a translucent indicator image Img2 (τ2) simulating a bucket 445 in a position in which the bucket 445 is estimated to actually exist is superimposed on a working environment image Img (τ2) at a position shifted from an image area representing the bucket 445, and is then outputted to the image output device 221.
