| 摘 要： | 连续调制TOF(time of flight)相机通过传感器接收连续发送给目标的连续调制波,并探测连续波的飞行(往返)时间,测得目标物距离,其图像存在多类误差来源。文章简要介绍了基于TOF的距离测量原理,同时针对误差产生的原因进行了总结,并且通过实验,区别了几种常见滤波器在不同状况下的对于距离图像的去噪效果,并对结果进行了研究与归纳。

| Abstract: | The time of flight(TOF) camera with continuous modulation receives the continuous wave(CW) sent to the target through the sensor,and measures the round trip time of CW to get the target’s distance.Its images include many types of errors.In this paper,the principle of distance measurement based on TOF is introduced,the causes of the errors are summarized,the difference of denoising performance of several common filters under different conditions is studied through experiments,and the results are analyzed. |
