Method for strengthening reality having interactive function and a system thereof

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 ...

Problems solved by technology

[0013] The disadvantage is that the requirements for markers are relatively high, and the shape of markers is required to be simple. The contrast between the edge of the shape and the background color is very clear and obvious, and there must be a quadrilateral frame composed of four straight sides as a clear boundary, otherwise the recognition effect will be affected.
