Problems solved by technology
[0004] Although online videos can be downloaded in advance, and video content can be preloaded, so that the appearance of black areas becomes almost invisible for a short time. However, there are a lot of video content in many applications, and it is impossible to download all of them locally and load them in advance. Therefore, it is necessary to Fundamentally solve the problem of black areas that may appear when AR video playback starts

Embodiment Construction
[0046] The method for providing augmented reality referred to in the present invention can be applied to various smart terminals with cameras, such as smart phones, tablet computers, smart TVs, game consoles, smart glasses or watches.
[0047] see figure 2 , which provides a schematic flowchart of an augmented reality method for an embodiment of the present invention, mainly including the following steps.
[0048] 201. The terminal obtains the current scene image through the camera, and displays it on the terminal screen. The content displayed at this time is generally a real reality scene, which is the same as the preview screen when taking a photo, and is usually called a background video.
[0049] 202. A target is detected in the current scene image. The type of object can be a marker or a natural image. If it is a natural image, it is generally required to have enough feature points, otherwise it is difficult to be identified and tracked. The first frame of a video ca...

The invention discloses a method for providing augmented reality. The method for providing augmented reality includes the following steps that a terminal obtains images of a current scene through a camera and displays the images on a terminal screen; a target is determined to exist in the images of the current scene through detection; video content corresponding to the target is loaded; the video content is played; the position of the video at the current frame image is obtained; when the position of the frame image is larger than zero, the frame image is rendered and overlaid to the scene displayed on the terminal screen; along with the playing process of the video, the sequential frame image is updated, rendered and overlaid to the scene. The invention further discloses the terminal for providing augmented reality. By means of the method and terminal for providing augmented reality, a temporary black zone can be avoided when an augmented reality video is played at the beginning.
Description
technical field [0001] The present invention relates to the technical field of augmented reality, in particular to a method and a terminal for providing augmented reality by playing videos. Background technique [0002] Augmented Reality (AR for short) is a new technology developed on the basis of virtual reality, also known as mixed reality or augmented reality. It is a technology that increases the user's perception of the real world through the information provided by the computer system, and superimposes the virtual information content on the scene of the real world, so as to realize the enhancement of reality. With the rapid popularization of smart mobile terminals with cameras, various augmented reality applications emerge in an endless stream, and are widely used in fields such as entertainment, life, medicine, advertising and education. Plane targets in augmented reality systems generally have artificial markers (Marker) and natural images, and some advanced AR syst...
