June 3, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- A patent by the inventors Tsao, Shiao-Li (Taipei, TW); Lin, Cheng-Lung (Nantou County, TW); Lin, Kaun-Ju (Changhua County, TW); Chen, Hsin-Chung (Banciao, TW), filed on April 1, 2009, was published online on May 20, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8732273 is assigned to National Chiao Tung University (Hsinchu, TW).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The present invention relates to a data inquiry system for three-dimensional (3D) location-based image, video, and information, and the inquiry method thereof, and more particularly to a data inquiry system, a data inquiry method for 3D location-based image, video, and information using space parameters and lens parameters to determine space coordinates of objects.

"At present, people can use a mobile phone with a global positioning system (GPS) sensor to locate themselves and further retrieve the knowledge and information of a geographic site in which they are visiting. In the existing prior art, a user can use a handheld device with a camera to take a picture on a object they feel interested and then the handheld device can utilize the image recognition technologies for detecting the object in the photo. For example, if tourists want to learn more about Eiffel Tower in France during their visits, the tourists simply need to use a mobile phone to take the picture of the Eiffel Tower, and an image recognition program installed in the mobile phone detects the tower and retrieves related information of the Eiffel Tower from a database via the Internet and shows related information to users. However, it is a challenging job to detect various different kinds of objects on earth with 100% accuracy. In addition to the image recognition, other known prior art uses latitude and longitude data of a GPS sensor installed on a mobile device to show the geographic location of the device as the location of the user, and roughly describes the information about the neighborhood of a scenic spot. However, the location of such mobile device cannot describe the user's interested object or photo taken for the object precisely, and thus cannot obtain the actual information related to the object. For example, a tourist visiting a park sees mountains around the park and wants to learn about a particular mountain, while taking a photo of or searching the mountain by a mobile phone, the GPS installed in the mobile phone cannot locate the position of the mountain accurately, and thus cannot provide the related knowledge and information of the mountain.

"In view of the aforementioned issue of an image data inquiry system, some patented technologies are used in a mobile device such as a digital camera and a global positioning system (GPS) receiver as disclosed in U.S. Pat. No. 7,146,179 entitled 'Portable imaging device employing geographic information to facilitate image access and viewing'. This method can obtain related information of the location of a photographer or an object, but cannot confirm the related information about the direction or the position of the photographed object.

"In another solution to the aforementioned problem, a plurality of more complicated and larger stacked camera modules are used, such that the exposure value of each different camera can be used for obtaining the direction and the height of an image of a photo taken. With the data of the direction and the height of the image, the relation of the spatial image of the object can be computed in a way as disclosed in U.S. Pat. No. 7,126,630 entitled 'Method and apparatus for omni-directional image and 3-dimensional data acquisition with data annotation and dynamic range extension method'. However, this method incurs higher cost with complexity for a client device and such device cannot be carried easily.

"Since the photo or video information recorded by the traditional methods actually shows the location of the photographer (or the camera equipment), but not the location of the photo itself, therefore users cannot obtain the desired information about the observed object through the GPS recording and service of a traditional way of taking a photo, or further obtain other photos and video related to the photographed object or information and knowledge about the object from such system. Obviously, such application is inconvenient.

"In view of the foregoing shortcomings of the prior art, the inventor of the present invention based on years of experience to conduct extensive researches and experiments, and finally developed a data inquiry system, a data inquiry method and a data creating method for location-based image, video, and information in accordance with the present invention to overcome the shortcomings of the prior art."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "The primary objective of the present invention is to provide a data inquiry system, a data inquiry method and a data creating method for location-based image, video, and information, particularly a technical area using space parameters and lens parameters to determine space coordinates of objects.

"To achieve the foregoing objective, the present invention provides a data inquiry system for 3D location-based image, video, and information, comprising a client device and a remote server. The client device comprises a space module and a first transmission module. The space module is provided for retrieving space parameters pointed by the client device, and the space parameters are transmitted to a remote server through the first transmission module. The remote server comprises a database, a processing module and a second transmission module, and the database stores a plurality of object data and a plurality of related image and video data, and each object data at least comprises an object space position parameter, and the processing module obtains the space parameters through the second transmission module, and a space inquiry range is determined according to the space parameters. The space inquiry range is a conical range that uses the location of the client device as a vertex, and the processing module inquires and finds out objects of the object space position parameter in the space inquiry range, and shows the object in the image data of the client device, and displays the image data on the client device.

"The client device further comprises a camera module if needed, for providing lens parameters. The space parameters and the lens parameters are transmitted by the first transmission module, and a space inquiry range is determined according to the space parameters and the lens parameters by the processing module. The remote server shows the inquired and finds objects and displays the object data on the client device.

"Further, users can select an object displayed by the client device to further identify the object in order to retrieve the related information of the object from the database.

"The related image data comprises a space description and an object index.

"The present invention further provides a data inquiry method for 3D location-based image, video, and information, and the method comprises the steps of: i. providing a plurality of object data, wherein each object data comprises an object space position parameter to describe the location of an object; ii. using a space module for retrieving a space parameter pointed by the client device; iii. determining a space inquiry range according to the space parameter, wherein the space inquiry range is a conical range using the location of the client device as a vertex; iv. inquiring and finding out an object data of the object space position parameter situated in the space inquiry range; and v. displaying the object data on the client device.

"This method further comprises the step of selecting the object data displayed by the client device to obtain a related image data.

"This method further comprises the steps of using a camera module to provide lens parameters, determining a space inquiry range according to the space parameters and the lens parameters, showing the inquired and found object data in the image data, and displaying the object data on the client device. The user can further identify the object shown on the client device for further retrieving the information of the object they are interested.

"The data inquiry system and a data inquiry method for location-based image, video, and information in accordance with the present invention have the advantage of using a space parameter to determine the space coordinates of an object.

"To make it easier for our examiner to understand the technical characteristics and effects of the present invention, we use a preferred embodiment accompanied with related drawings for the detailed description of the present invention as follows."
