According to the present invention, a moving body capable of moving within a preset range of movement acquires an image from the environment surrounding the location of the moving body, and determines entry determination conditions for obtaining a result of an entry determination as to whether or not the moving body is allowed to enter a region identified by the location of the moving body and the image. A management terminal outputs the entry determination conditions and the image to an output device, and receives modification information relating to the entry determination conditions from an input device. A server uses the modification information received by the input device of the management terminal to perform learning, including updating of the entry determination conditions, thereby setting the movement range of the moving body, the movement of which is controlled in accordance with the entry determination result.

Autonomous mobile device, autonomous movement system, and autonomous movement method

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.
