摘要

本文提出了一种伪四抽头像素结构的ToF深度传感器插值方法。伪四抽头像素架构对不同的行像素使用不同的调制信号。虽然更快的数据采集减少了运动伪影，但两个垂直像素的深度计算降低了深度分辨率。该方法采用偏移值作为相似权值来提高深度分辨率。实验结果表明，在垂直方向上，边缘伪影得到了改善。

Interpolation method for ToF depth sensor with pseudo 4-tap pixel architecture

This paper presents an interpolation method for ToF depth sensor with pseudo 4-tap pixel architecture. Pseudo 4-tap pixel architecture uses different modulation signals for different row pixels. While faster data acquisition reduces motion artifacts, depth calculation with two vertical pixels lowers depth resolution. The proposed method uses offset values for similarity weights to improve depth resolution. Experimental results show that edge artifact is improved in the vertical direction.
