基于数字相机和时间心理视觉调制的增强现实技术

为了拓展增强现实（AR）的实用性，提出一种基于时间心理视觉调制（TPVM）技术和数字相机来实现AR效果的方法。首先将AR中的标记嵌入数字屏幕的媒体内；然后利用人眼识别感知与数字相机拍摄图像形成在数字屏幕或者投影仪上原理的差异，使用数字相机设备获取数字屏幕图像内人眼不易察觉的AR标记；最后在获取标记的智能设备中显示AR效果。仿真结果显示，将数字相机与TPVM技术相结合，能够很好地将AR标记隐藏在影像中，同时人眼无法察觉，而数字相机则能准确地识别AR标记并实现AR效果。通过手机替代3D眼镜等额外设备，降低了AR的使用限制，拓展其实用性。

Augmented reality approach based on digital camera and temporal psycho-visual modulation

In order to extend the practicality of Augmented Reality (AR), a method based on Temporal Psycho Visual Modulation (TPSM) technology and digital camera to realize AR effect was proposed. First, the AR tags were embedded in the digital screen of the media. Based on the principle difference between the human eye to identify the perception and the digital camera to capture the image formed in the digital screen or projector, the digital camera equipment was used to obtain the digital screen image with AR tags which are not easily to be detected by human eye. Finally, the AR effect was displayed on the smart device that gets the AR tags. Simulation results show that the combination of AR and TPVM technology can accurately identify the AR tags in the image and achieve AR effect, while the human eye can not detect the AR tags. Through the mobile phone instead of 3D glasses and other extra equipment, the use restrictions of AR are reduced, and the practicality of AR is also expanded.
