论文摘要
飞行时间（TOF）摄像机在3D成像中变得越来越流行。从几个方面研究了它们的最佳用法。开放的研究问题之一是，当两个或多个TOF摄像机同时运行时，可能会出现多大型干扰问题。在这项工作中，我们提出了一种有效的方法来同步多个操作TOF摄像机。我们的方法基于时间划分的多路复用，但与传统的乘法不同，它不会降低有效的相机框架速率。此外，对于非同步摄像机，我们提供了一种可靠的方法，可以从其相应的视频流中提取不受多机构干扰问题的框架。我们通过一系列实验演示了我们的方法，并提供不同级别的支持，可用于触发，从硬件触发到纯粹的随机软件触发。
Time-of-flight (ToF) cameras are becoming increasingly popular for 3D imaging. Their optimal usage has been studied from the several aspects. One of the open research problems is the possibility of a multicamera interference problem when two or more ToF cameras are operating simultaneously. In this work we present an efficient method to synchronize multiple operating ToF cameras. Our method is based on the time-division multiplexing, but unlike traditional time multiplexing, it does not decrease the effective camera frame rate. Additionally, for unsynchronized cameras, we provide a robust method to extract from their corresponding video streams, frames which are not subject to multicamera interference problem. We demonstrate our approach through a series of experiments and with a different level of support available for triggering, ranging from a hardware triggering to purely random software triggering.
