摘要
分析了现有模拟分时立体成像系统的原理和存在闪烁问题的原因,由于两路CCD信号分时显示使帧频下降,图像存在一定的闪烁感,提出了一种改进的立体成像方案,该方案基于数字视频处理,采用高速的数字视频解码芯片和DSP芯片,提高了图像显示帧频达到无闪烁立体成像的目的,而且利用插场算法提高了图像的清晰度,有利于对进一步实现视觉跟踪控制或利用视觉信息进行自动控制。
In this paper,the principle and the reason of flicker problem existing in time-sharing analog3D imaging system are analyzed.Two channels of CCD signal are displayed alternately and the frame frequency is declined so the flicker problem is engendered.An improved project based on digital video is proposed in this pa-per.It adopts high-speed digital video decoder and DSP,increases the frame frequency of the image and forms flicker-free3D image.Furthermore the definition of3D image is also improved through interpolation arithmetic and it is propitious to implement visual track control or visual feedback control.
