Abstract

This invention discloses a data inquiry system for three-dimensional location-based image, video, and information, which comprises a client device and a remote server. The client device provides space parameters and lens parameters to the remote server through a transmission module. The remote server determines a space inquiry range by the space parameter and lens parameter, inquires an object data of an object space position parameter at the space inquiry range, shows the object data in an image data displayed by the client device to facilitate users to identify the desired viewing object, and further inquires the object data and related image and/or video data.

Claims

1. A data inquiry system for 3D location-based image, video, and information, comprising:

a client device, having a space module and a first transmission module, and the space module being used for retrieving space parameters pointed by the client device, and the space parameters being transmitted by the first transmission module, wherein the space parameters are retrieved by only the space module itself; and

a remote server, having a database, a processing module and a second transmission module, and the database being provided for storing a plurality of object data of a plurality of objects and a plurality of related image and video data, and each of the plurality of object data comprising an object space position parameter, and the processing module obtaining space parameters through the second transmission module, and determining a space inquiry range according to the space parameter, and the space inquiry range being a conical range that uses the location of the client device as a vertex, and the processing module inquiring and identifying an object data of the object space position parameter situated in the space inquiry range, filtering out a first part of the plurality of object data, which is smaller than a critical value, and displaying a second part of the plurality of object data, which is larger than the critical value, on the client device, wherein the second part of the plurality of object data, which is displayed by the client device, is used for enabling a user to identify an object from the second part of the plurality of object data and to further retrieve the image and video data related to the object, which is identified by the user, wherein the critical value is an access rank of each of the plurality of object data or a magnitude, which is displayed on the client device and corresponded to each of the plurality of object data, of each of the plurality of object data.

2. The inquiry system of claim 1, wherein the related image data comprises a space description and an object index.

3. The inquiry system of claim 1, wherein the space module comprises a global positioning system (GPS), a direction sensor and an elevation angle sensor.

4. The inquiry system of claim 3, wherein the elevation angle sensor comprises a 3-axis accelerator or a gyroscope.

5. The inquiry system of claim 3, wherein the direction sensor comprises a digital compass.

6. The inquiry system of claim 1, wherein the space module only comprises a global positioning system.

7. The inquiry system of claim 1, wherein the object space position parameter is a three dimensional coordinate.

8. The inquiry system of claim 1, wherein the object data further comprises an object description data, an access rank, and a related image data index.

9. The inquiry system of claim 1, wherein the first transmission module transmits data via a wired or a wireless transmission.

10. The inquiry system of claim 1, wherein the second transmission module transmits data via a wired or a wireless transmission.

11. The inquiry system of claim 1, wherein the client device further comprises a camera module for providing lens parameters, and the space parameters and the lens parameters are transmitted through the first transmission module, and the processing module determines the space inquiry range and the object according to the space parameters and the lens parameters, and shows the inquired object data in the image data displayed on the client device.

12. The inquiry system of claim 11, wherein the image data is a static image or a video.

13. The inquiry system of claim 11, wherein the plurality of object data and the plurality of the related image data stored in the database are partially or wholly cached into a memory of the client device.

14. A data inquiry method for location-based image, video, and information, comprising the steps of:

(a) providing a plurality of object data of a plurality of objects, and each object data at least comprising an object space position parameter;

(b) using a space module, for retrieving space parameters pointed by the client device, wherein the space parameters are retrieved by only the space module itself;

(c) determining a space inquiry range according to the space parameters, wherein the space inquiry range is a conical range using the location of the client device as a vertex;

(d) inquiring and identifying an object data of the object space position parameter situated in the space inquiry range;

(e) filtering out a first part of the plurality of object data, which is smaller than a critical value, wherein the critical value is an access rank of each of the plurality of object data or a magnitude of an object, which is displayed on the client device and corresponded to each of the plurality of object data, of each of the plurality of object data; and

(f) displaying a second part of the plurality of object data, which is larger than the critical value, on the client device for enabling a user to identify an object from the second part of the plurality of object data and to further retrieve the image and video data related to the object, which is identified by the user.

15. The data inquiry method of claim 14, wherein the space module comprises a global positioning system, a direction sensor and an elevation angle sensor.

16. The data inquiry method of claim 15, wherein the elevation angle sensor comprises a 3-axis accelerator or a gyroscope.

17. The data inquiry method of claim 15, wherein the direction sensor comprises a digital compass.

18. The data inquiry method of claim 15, wherein the space module comprises a global positioning system only.

19. The data inquiry method of claim 14, wherein the object space position parameter is a three-dimensional coordinate.

20. The data inquiry method of claim 14, wherein the client device further comprises an operating interface provided for a user to identify an object from a screen or an object menu.

21. The data inquiry method of claim 14, wherein the object data further comprises an object description data, an access rank and a related image data index.

22. The data inquiry method of claim 14, wherein the lens parameter comprises a viewing angle.

23. The data inquiry method of claim 14, further comprising the steps of:

using a camera module to retrieve an image data, and provide lens parameters of the camera module;

showing the potential objects on the image data;

displaying the image data on the client device; and
