A vacant house determination device comprising: learning means for acquiring map data that includes a predetermined district and at least includes coordinates of a vacant house surveyed among houses included in a map, attribute information regarding a structural object, and topographic information, and a captured image that is associated with the map data and includes the predetermined district from a storage device, and generating machine learning data for presuming that a house in the captured image is the vacant house, the machine learning data being generated based on, among pieces of pixel information representing sites of the houses in the captured image including the predetermined district, the pixel information representing a site of a house corresponding to the coordinates of the vacant house; formula deriving means for deriving a vacant house probability calculation formula with respect to a district specified by a user, based on the map data; vacant house probability calculating means for calculating the vacant house probability with respect to each of the houses included in the specified district in the map data, by using the vacant house probability calculation formula; and vacant house determining means for determining whether a house having the vacant house probability equal to or more than a predetermined value is a vacant house in the specified district, based on machine learning data for presuming that a house in the captured image is a vacant house, the machine learning data being generated based on, among pieces of pixel information representing sites of the houses in the captured image, the pixel information representing a site of a house corresponding to the coordinates of the vacant house, and image information regarding a site of a house having the vacant house probability equal to or more than a predetermined value; map generating means for generating vacant house map information indicating a position of the house that has been determined to be a vacant house; and output means for outputting the vacant house map information to a predetermined device or the storage device. learning means for acquiring map data that includes a predetermined district and at least includes coordinates of a vacant house surveyed among houses included in a map, attribute information regarding a structural object, and topographic information, and a captured image that is associated with the map data and includes the predetermined district from a storage device, and generating machine learning data for presuming that a house in the captured image is the vacant house, the machine learning data being generated based on, among pieces of pixel information representing sites of the houses in the captured image including the predetermined district, the pixel information representing a site of a house corresponding to the coordinates of the vacant house; formula deriving means for deriving a vacant house probability calculation formula with respect to a district specified by a user, based on the map data; vacant house probability calculating means for calculating the vacant house probability with respect to each of the houses included in the specified district in the map data, by using the vacant house probability calculation formula; and vacant house determining means for determining whether a house having the vacant house probability equal to or more than a predetermined value is a vacant house in the specified district, based on machine learning data for presuming that a house in the captured image is a vacant house, the machine learning data being generated based on, among pieces of pixel information representing sites of the houses in the captured image, the pixel information representing a site of a house corresponding to the coordinates of the vacant house, and image information regarding a site of a house having the vacant house probability equal to or more than a predetermined value; machine learning data for presuming that a house in the captured image is a vacant house, the machine learning data being generated based on, among pieces of pixel information representing sites of the houses in the captured image, the pixel information representing a site of a house corresponding to the coordinates of the vacant house, and image information regarding a site of a house having the vacant house probability equal to or more than a predetermined value; map generating means for generating vacant house map information indicating a position of the house that has been determined to be a vacant house; and output means for outputting the vacant house map information to a predetermined device or the storage device.
