Abstract

The present disclosure provides methods, devices, and computer-readable media for target acquisition in a three dimensional building display are described herein. One or more embodiments include extracting building information modeling semantic data of each of a number of modeled objects in a visual scene of a three dimensional building display, determining a semantic space for each of the number of modeled objects based, at least in part, on the building information modeling semantic data, adjusting a scale factor of the three dimensional building display based, at least in part, on the semantic space of each of the number of modeled objects, and acquiring a target of at least one of the modeled objects using the adjusted scale factor.

Claims

1. A method for target acquisition in a three dimensional building display, comprising:

extracting building information modeling semantic data of each of a number of modeled objects in a visual scene of a three dimensional building display;

determining a semantic space for each of the number of modeled objects based, at least in part, on the building information modeling semantic data;

adjusting a scale factor of the three dimensional building display based, at least in part, on the semantic space of each of the number of modeled, wherein adjusting the scale factor of the three dimensional building display includes decreasing the scale factor when the number of modeled objects in the visual scene is above a threshold value; and

acquiring a target of at least one of the modeled objects using the adjusted scale factor.

2. The method of claim 1, wherein adjusting the scale factor of the three dimensional building display includes increasing the scale factor when the number of modeled objects in the visual scene is below a threshold value.

3. The method of claim 1, wherein the method includes adjusting the scale factor of the three dimensional building display based, at least in part, on a category of the visual scene.

4. The method of claim 1, wherein the method includes determining interaction context information based on the number and category of modeled objects in the visual scene.

5. The method of claim 4, wherein the method includes providing an additional visual scene of the three dimensional building display based, at least in part, on the interaction context for each of the number of modeled objects.

6. The method of claim 1, wherein the method includes acquiring an appointed target based on a bounding box.

7. A non-transitory computer-readable medium storing instructions for target acquisition in a three dimensional building display, executable by a computer to cause the computer to:

display a number of objects of a three dimensional building display in an interaction mode;

adjust a scale factor of the interaction mode between a visual space and a motor space, wherein adjusting the scale factor of the interaction mode includes increasing the scale factor when the number of displayed objects in the interaction mode is below a threshold value;

extract building information modeling semantic data of at least one of the number of displayed objects;

acquire a target of at least one of the number of displayed objects including the building information modeling semantic data of the acquired target;

determine if the acquired target triggers a transition to an additional interaction mode; and

transition to the additional interaction mode if the acquired target triggers the transition to the additional interaction mode.

8. The non-transitory computer readable medium of claim 7, wherein the interaction mode includes a rotate function, a zoom function, and a pan function.

9. The non-transitory computer readable medium of claim 7, wherein the interaction mode includes an interaction mode from the group including:

a building view mode, a floor plan view mode, a room view mode, and a device view mode.

10. The non-transitory computer readable medium of claim 7, wherein the interaction mode is a floor plan view mode and the instructions include instructions executable by the computer to:

display, in the floor plan view mode, a number of rooms of the three dimensional building; and

identify, in the floor plan view mode, a number of properties of a highlighted room of the number of rooms.

11. The non-transitory computer readable medium of claim 7, wherein the interaction mode is a building view mode and the instructions include instructions executable by the computer to:

zoom in on a floor in the three dimensional building display; and

switch the three dimensional display to a display of the floor upon zooming in on the floor in the three dimensional building display.

12. The non-transitory computer readable medium of claim 7, wherein the interaction mode is a floor plan view mode and the instructions include instructions executable by the computer to:

zoom in on a room in the three dimensional building display; and

switch the three dimensional display to a display of the room upon zooming in on the room in the three dimensional building display.

13. The non-transitory computer readable medium of claim 12, wherein the instructions include instructions executable by the computer to:

rotate the display based, at least in part, on the room; and

decrease the scale factor from a size of the room and a size of the number of objects.

14. The non-transitory computer readable medium of claim 7, wherein the additional interaction mode is a different interaction mode than the interaction mode.

15. The non-transitory computer readable medium of claim 7, wherein the instructions executable by the computer to transition includes a transition from at least one of the group including:

a transition from a building view mode to a floor plan view mode;

a transition from a floor plan view mode to a room view mode;

a transition from a room view mode to a device view mode;

a transition from a device view mode to a room view mode;
