Official abstract text for this publication.
Proposed are a mobile object, an information processing apparatus, an information processing method, and a program that are capable of improving the accuracy of determining whether to land a drone aircraft on a landing surface. The mobile object of the present technology includes a control unit. The control unit calculates a temporal change of a landing surface from images in which the landing surface for the mobile object is imaged in time series by an imaging unit of the mobile object in a hovering state, and determines whether to land the mobile object on the landing surface on the basis of the calculated temporal change.
Opening claim text (preview).
The invention claimed is: 1. A mobile object, comprising a control unit configured to calculate a temporal change of a landing surface from images in which the landing surface for the mobile object is imaged in time series by a camera of the mobile object in a hovering state, discriminate an environment of the landing surface on a basis of the images, and cause the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a threshold value corresponding to the discriminated environment, wherein different threshold values correspond to respective different discriminated environments, and the control unit is implemented via at least one processor. 2. The mobile object according to claim 1 , further comprising a detection unit configured to detect an altitude of the mobile object from the landing surface, wherein the control unit is further configured to determine whether to land the mobile object on the landing surface on a basis of the altitude and the temporal change, and the detection unit is implemented via at least one processor. 3. The mobile object according to claim 2 , wherein the control unit is further configured to cause the mobile object to approach the landing surface when the altitude of the mobile object is larger than a predetermined threshold value. 4. The mobile object according to claim 3 , wherein the threshold value is an altitude at which the landing surface changes with time due to wind generated from the mobile object. 5. The mobile object according to claim 3 , wherein the control unit is further configured to determine whether to land the mobile object on the landing surface on a basis of the discriminated environment, the temporal change, and the altitude. 6. The mobile object according to claim 5 , wherein the control unit is further configured to cause the mobile object to land on the landing surface based on the discriminated environment being a water surface and the temporal change being equal to or less than a threshold value corresponding to the water surface. 7. The mobile object according to claim 1 , wherein the control unit is further configured to perform image processing on the images to remove objects different from the landing surface, and calculate the temporal change from the images on which the image processing is performed. 8. The mobile object according to claim 1 , wherein the mobile object is a flying object. 9. The mobile object according to claim 1 , wherein the control unit is further configured to control the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a first threshold value corresponding a first discriminated environment, and control the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a second threshold value corresponding a second discriminated environment, and the first threshold value is different than the second threshold value and the first discriminated environment is different than the second discriminated environment. 10. An information processing apparatus, comprising a control unit configured to calculate a temporal change of a landing surface from images in which the landing surface for a mobile object is imaged in time series by a camera of the mobile object in a hovering state, discriminate an environment of the landing surface on a basis of the images, cause the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a threshold value corresponding to the discriminated environment, and output a result of the determination to the mobile object, wherein different threshold values correspond to respective different discriminated environments, and the control unit is implemented via at least one processor. 11. The information processing apparatus according to claim 10 , wherein the information processing apparatus is a server. 12. An information processing method, comprising: calculating a temporal change of a landing surface from images in which the landing surface for a mobile object is imaged in time series by a camera of the mobile object in a hovering state; discriminating an environment of the landing surface on a basis of the images; and causing the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a threshold value corresponding to the discriminated environment, wherein different threshold values correspond to respective different discriminated environments. 13. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute an information processing method, the method comprising: calculating a temporal change of a landing surface from images in which the landing surface for a mobile object is imaged in time series by a camera of the mobile object in a hovering state; discriminating an environment of the landing surface on a basis of the images; and causing the mobile object to land on the landing surface on a basis of the calculated temporal change exceeding a threshold value corresponding to the discriminated environment, wherein different threshold values correspond to respective different discriminated environments.
