Abstract
A region removing unit determines a coordinate region of a boom indicating a region in distance image data by using posture information acquired by an acquisition unit, and removes pixel data constituting the determined coordinate region from the distance image data. An interference determination unit detects an interference object that is a work device or a grasped object of the work device by using the distance image data obtained by removing the pixel data constituting the coordinate region to determine danger of interference of the detected interference object in a cab. When the interference determination unit determines that there is danger of interference, an interference prevention unit performs at least one of a warning to an operator and operation restriction of the work device.
