Abstract: When a moving body is remotely operated, a delay in transmission of an image and information acquired from the moving body becomes a problem since immediate transmission of an operation to the moving body cannot be expected. When a frame rate is decreased or a resolution is reduced to decrease the amount of image data to prevent transmission delay of the image data, it is difficult to grasp motions of other moving bodies. As a result, when a certain amount of time is required to transmit a camera image and a moving obstacle, the movement of the obstacle and the movement of the moving body are estimated. The estimated image is generated based on a current image, and is presented to an operator via a monitor. Accordingly, it is possible to reduce instability and a risk associated with transmission delay to safely operate the moving body.
