Embodiment Construction

[0079] Such as figure 1 As shown, an augmented reality system with interactive functions, including:

[0080] The video frame training module is used to select or extract a front view of a landmark, train the landmark, and obtain training data;

[0081] A video frame correction module, connected to the video frame training module, used to calculate and correct the camera internal parameters of the marker image;

[0082] The video frame capture module is connected with the video frame training module and the video frame correction module, and is used to correct each frame in the real environment captured by the camera using the data in the video frame correction module, Recognize markers based on the training data in the video frame training module. If markers are included, calculate the relative position matrix of the markers in the camera coordinate system, and pass the brightness of the identified markers and the front view of the markers. Perform comparison to estimate th...

Abstract

The invention provides a method for strengthening reality having interactive function and a system thereof, comprising initializing system environment, configuring system parameters, selecting or extracting a mark front view, training the mark to obtain the training data, calculating and correcting the intrinsic parameters of the camera of the mark image; correcting each frame of the true environment shot by the camera; identifying the mark based on the training data, calculating the relative position matrix of the mark in the camera coordinate system, comparing the identified mark and the brightness of the mark front view to evaluate the lighting information of the mark in the environment; finding the corresponding virtual model according to the identified mark, using the extracted position matrix of the mark to determine the position of the model, drafting the virtue model, setting the interaction between the interactive region and the user. The invention greatly reduces the limit to the mark, and can be used for marking the map and completed two dimensional image, and also can randomly synthesize three-dimensional model on the two dimensional image.

Description

technical field [0001] The invention belongs to the field of augmented reality technology, in particular to a method and system of augmented reality, which is applied to the fields of virtual reality and computer vision, and uses pattern recognition and virtual reality technology to add content and enhance effects to the real image frames collected by video . Background technique [0002] Augmented reality (AR, Augmented Reality) is a technology that uses virtual objects to enhance the reality of real scenes. Augmented reality is based on the real physical environment collected by acquisition devices such as cameras, by annotating virtual generated information such as text, two-dimensional images, and three-dimensional models on objects in the real physical environment displayed on the display screen, so as to realize the user's physical environment Notes, descriptions, or enhancements and emphasis on certain effects of the real-world environment. For example, when a user ...
