A control device included in an industrial vehicle, the control device comprising: an image analysis unit configured to determine whether or not a detection object is detected around the industrial vehicle in a captured image of an image-capturing device including four cameras (20a, 20b, 20c, 20d) and to output distance information indicating a distance between the industrial vehicle and the detection object, the region in which the detection object has been detected on the basis of a position at which the detection object is captured in the image, and detection camera information indicating a camera that has captured the captured image in which the detection object is included; an operation determination unit configured to specify, as operation information, content of an operation performed with respect to the industrial vehicle by a driver; an important detection object specifying unit configured to specify one of a plurality of detection objects on the basis of a state of the industrial vehicle, on the basis of the operation information and the distance information, and to specify the region in which the distance is shortest among the regions in which the detection object has been detected as the region to which most attention is to be paid; a surroundings display unit including a display that is configured to display a bird's-eye view image of surroundings of the industrial vehicle created from the captured image of the image-capturing device; a detection object notification device comprising four L-shaped lamps (222a, 222b, 222c, 222d) provided along an outer periphery of the display, and a buzzer configured to emit a warning sound when a detection object has been detected by the important detection object specifying unit, wherein the detection object notification device performs a notification of the region to which most attention is to be paid by lighting up the L-shaped lamps using different aspects in case the detection object cannot be displayed within the bird's eye view image; and a storage unit configured to store information necessary for a process that is performed by the control device. an image analysis unit configured to determine whether or not a detection object is detected around the industrial vehicle in a captured image of an image-capturing device including four cameras (20a, 20b, 20c, 20d) and to output distance information indicating a distance between the industrial vehicle and the detection object, the region in which the detection object has been detected on the basis of a position at which the detection object is captured in the image, and detection camera information indicating a camera that has captured the captured image in which the detection object is included; an operation determination unit configured to specify, as operation information, content of an operation performed with respect to the industrial vehicle by a driver; an important detection object specifying unit configured to specify one of a plurality of detection objects on the basis of a state of the industrial vehicle, on the basis of the operation information and the distance information, and to specify the region in which the distance is shortest among the regions in which the detection object has been detected as the region to which most attention is to be paid; a surroundings display unit including a display that is configured to display a bird's-eye view image of surroundings of the industrial vehicle created from the captured image of the image-capturing device; a detection object notification device comprising four L-shaped lamps (222a, 222b, 222c, 222d) provided along an outer periphery of the display, and a buzzer configured to emit a warning sound when a detection object has been detected by the important detection object specifying unit, wherein the detection object notification device performs a notification of the region to which most attention is to be paid by lighting up the L-shaped lamps using different aspects in case the detection object cannot be displayed within the bird's eye view image; and a storage unit configured to store information necessary for a process that is performed by the control device.
