1. A vehicle surroundings monitoring device comprising: an object detection unit for detecting objects in the periphery of a vehicle, the object detection unit being provided to the vehicle; a vehicle image generation unit for generating an image of the vehicle with the point of view set above the vehicle; a periphery image generation unit for generating an image of the periphery of the vehicle from the point of view, the image being partitioned into a plurality of regions in the periphery of the image of the vehicle; a position-calculating unit for calculating a corresponding position in the image of the periphery on the basis of detection results of the object detection unit; a degree-of-confirmation assessment unit for assessing whether a degree of confirmation of the detection results detected by the object detection unit meets or exceeds an assessment threshold set in advance; and an indicator unit for indicating the corresponding position in the image of the periphery based on the calculation results of the position-calculating unit when the degree of confirmation of the detection results meets or exceeds the assessment threshold, and for indicating the corresponding region in the image of the periphery on the basis of the calculation results of the position-calculating unit when the degree of confirmation of the detection results is less than the assessment threshold.
