Environment map automatic creation device
Provided is an environment map automatic creation device using a flying object. The environment map automatic creation device includes a travelable area extraction unit that extracts a travelable area where a vehicle can travel in a certain area based on three-dimensional shape information of an area for creating an environmental map, which is acquired by a sensor in a flying object, an area category determination unit that determines a category of the travelable area, a complementary portion determination unit that determines whether or not to measure a complementary portion which complements the travelable area based on the travelable area and the category, and a complementary measurement portion presentation unit that presents the complementary measurement portion.
1. An environment map automatic creation device comprising:
a travelable area extraction unit that acquires three-dimensional shape information of an area, which is acquired by a sensor in a flying object, determines one or more obstacles within the area based on the three-dimensional shape information, determines a travelable area devoid of the determined one or more obstacles and generates an environmental map;
an area category determination unit that determines a category of a portion of the travelable area among a plurality of categories including a category indicating there is insufficient three-dimensional shape information for a respective portion of the travelable area;
a complementary portion determination unit that determines there is a complementary portion within the area which complements the travelable area based on portions of the travelable area and the category of the portions of the travelable area indicating there is insufficient three-dimensional shape information; and
a complementary measurement portion presentation unit that displays the complementary measurement portion on a display.
2. The environment map automatic creation device according to claim 1 ,
wherein the area category determination unit determines a category of the travelable area based on a shape of the traveling area.
3. The environment map automatic creation device according to claim 1 ,
wherein the area category determination unit determines a category of the travelable area based on a color of the traveling area.
4. The environment map automatic creation device according to claim 1 ,
wherein the category of the travelable area include a road and a square, and
wherein upon determining an end of the road is not connected to the square, the complementary portion determination unit determines that the complementary portion includes at least a portion of the end of the road.
5. The environment map automatic creation device according to claim 1 ,
wherein the road and the square are included in the category of the travelable area, and
in a case where any one of the areas determined by the area category determination unit as the square is not connected to the road, the complementary portion determination unit determines a boundary portion of the travelable area of the area determined as the square to be the complementary portion.
6. The environment map automatic creation device according to claim 1 ,
wherein the complementary portion is measured by an unmanned vehicle.
7. The environment map automatic creation device according to claim 1 , further comprising:
a complementary three-dimensional shape information storage unit that stores complementary three-dimensional shape information serving as the three-dimensional shape information of the complementary portion;
a measurement information integration unit that matches the complementary three-dimensional shape information and the three-dimensional shape information; and
a map updating unit that updates the environmental map based on the three-dimensional shape information matched by the measurement information integration unit.
