CN-122001998-A - Video conference system and stereoscopic modeling method using same

Abstract

The invention provides a video conference system and a three-dimensional modeling method using the same. The stereo modeling method of the video conference comprises the following steps. A movable image capturing device takes a plurality of photos of an object and records modeling information corresponding to each photo. The mobile image capturing device transmits the photo and the modeling information to a first electronic device. The first electronic device encodes each modeling information into each photo in a hidden watermark manner. The first electronic device transmits the photo with the hidden watermark to a second electronic device. The second electronic device receives a photograph with a hidden watermark. The second electronic device decodes each modeling information for each hidden watermark of each photo. The second electronic device establishes a stereoscopic model according to the photos and the modeling information. The second electronic device shows the stereoscopic model.

Description

Video conference system and stereoscopic modeling method using same Technical Field The present invention relates to a conference system and a conference construction method, and more particularly, to a video conference system and a stereo modeling method using the same. Background With the progress of video technology, people can conduct remote video communication and discussion through video conference software. In the video conference process, the presenter can transmit the images to the participants as long as he/she opens the shots. In the course of a video conference, a presenter can show an object, an indoor environment or a beautiful scene through a lens. In order to allow the participants to completely see the appearance of the object, the presenter can rotate the object or take a photograph around the object. However, even though the presenter tries to capture various details of the object, the meeting presenter may still have an angle at which to look in close order, and the presenter is not continually required to redisplay the object at that angle. Accordingly, researchers are working to develop a technique that allows participants to actively adjust the angle without requiring the presenter to redisplay. Disclosure of Invention The invention relates to a video conference system and a three-dimensional modeling method using the same. In the video conference process, the first electronic device of the presenter transmits photos of all directions showing an object to the second electronic device of the participant through the network. In addition, modeling information is added to the photo, so that the second electronic device can quickly establish a stereoscopic model. By utilizing the stereoscopic model, the participants can rotate the object by themselves through a mouse or a keyboard so as to completely see the looks of each surface of the object.
