Method and system for tracking, three-dimensionally superposing and interacting target object without special mark

The invention belongs to the technical field of computer application, and provides a method and a system for tracking, three-dimensionally superposing and interacting a target object without a special mark. The method comprises the following steps of: firstly, segmenting the target object from an image shot by a camera, and creating a characteristic template of the target object automatically; next, directly identifying the target object by utilizing the characteristics of the target object, and calculating three-dimensional information (relative to the camera) of the target object; and finally, superposing a virtual object or an animated picture in a three-dimensional coordinate system in a realistic space through a graphics engine in real time. According to the method disclosed by the invention, video images and template images are subjected to characteristic matching via a surf algorithm so as to finish the calibration on the camera, so that real-time tracking and real-time three-dimensional superposing of the target object without the special mark are realized; for each frame of video image, three-dimensional coordinate information of the target is calculated in real time, so that interaction of a person or an object in reality with a virtual person or a virtual object is realized; and therefore, the method and the system disclosed by the invention are relatively high in degree of automation and have relatively popularization and application values.

Head-mounted type virtual reality device and virtual reality system

The invention discloses a head-mounted type virtual reality device. The device comprises a shell, a head-mounted display, a plurality of positioning light beam receivers and a processor. The head-mounted display is located in the shell and used for displaying a three-dimensional virtual scene. The positioning light beam receivers are embedded in the outer surface of the shell and used for receiving positioning light beams which conduct sweeping in a laser positioning base station according to a preset sweeping period. The relative space position relations between the positioning light beam receivers are fixed. The processor is located in the shell and used for determining the position of the head-mounted type virtual reality device according to the times when the four positioning beam receivers receive the positioning light beams respectively, the sweeping period, the relative space position relations and a preset position of the positioning light beam emitting device. Therefore, when a three-dimensional virtual image is shown to a user through the head-mounted type virtual reality device, position information of the user can be determined. Therefore, the position information of the user can be displayed in the virtual scene through the head-mounted type virtual reality device, and interaction between the user and the virtual reality scene can be achieved.
