立体显示可以为观察者提供场景中物体的深度信息,并使观察者有身临其境的感觉.为了搭建低成本可应用于辅助远程操纵的实时画面立体显示系统原型,利用双目网络摄像头和立体显示设备,在未对相机标定情况下,采用非标定立体校正的方法,设计了一套实时立体显示系统,提供了色差式和快门式2种立体显示方式,并通过 MOS 方法对系统的立体显示效果进行了主观评价.实验结果表明,经过立体校正后的左右摄像头图像行是对准的.在使用了多线程技术对左右图像并行处理的情况下,系统输出立体图像的帧频从21 Hz 提高到了30 Hz,满足实时性的要求.在立体显示效果评价中,色差式和快门式立体显示分别得到了7.67分和9.08分,说明立体效果基本令人满意.
Stereoscopic display can provide depth information and immersive knowledge about the sce-nario for the observers.In order to build the low-cost prototype of stereoscopic display system which can aid remote operation,a real-time stereoscopic display system without the calibration to the camera was designed.The system utilized binocular web cameras and stereo display device to provide two stereoscopic display modes:anaglyphic mode and active shutter mode,the performance of which are evaluated by MOS method.Experimental results show that the two images of the binocular web cameras are row-aligned rectified.In the case of parallel processing of images with multi-thread tech-nique,the frame rate of the stereo image output is upgraded to 30 Hz from 21 Hz,which meets the real time requirements.Evaluation proves that the score of anaglyphic mode and active shutter mode are 7.67 and 9.08,respectively.The performance of stereoscopic display is basically satisfactory.
