A system includes a work machine, a camera, and a processor. The camera captures an image including a periphery of the work machine. A processor acquires image data indicative of a captured image captured by a camera. The processor acquires, from image data, a specific object present within the captured image and a distance from the work machine to the specific object by performing image analysis using an object detection model. The object detection model is trained an image of the specific object and the distance to the specific object. The processor controls the work machine based on the distance from the work machine to the specific object when the specific object is detected in the captured image.
