Smart drone audition: A search and rescue drone system that listens and communicates

本杰明·严博士将他在奥克兰大学的部分研究融入了东京工业大学相关的无人机试飞项目。具体地说，他结合了他在声源增强方面的工作中的技术，以改进使用多架无人机的声源跟踪。这产生了一份提交给2023年IEEE/RSJ智能机器人和系统国际会议的会议论文。这篇论文目前正在审查中。我们已经向IEEE/ACM音频、语音和语言处理会刊提交了一篇无人机试听的期刊文章。具体地说，我们提出了一种可用于无人机试听声源增强算法的噪声协方差矩阵估计方法。虽然这项研究是在Benjamin Yen博士在奥克兰大学期间进行的，但它完全属于JSPS博士后奖学金建议的研究范围，并将在此次奖学金期间进一步发展。本文目前正在进行重大修订。我们已经进行了一次重大的户外实验，以收集必要的数据来对各种无人机试听算法进行性能评估。这包括无人机噪音和移动目标声源的准确录音。此外，还记录了目标声源运动的准确GPS数据。这些测量将有助于评估所提出的算法的声源跟踪性能。我们已经计划了一系列与研究主题相关的研究课题，供我们自己和B4/硕士新生研究。

Dr. Benjamin Yen has integrated some of his research at the University of Auckland into related drone audition projects at the Tokyo Institute of Technology. Specifically, he incorporated techniques from his work in sound source enhancement to improve sound source tracking using multiple drones. This has yielded a conference paper submission to the 2023 IEEE/RSJ International Conference on Intelligent Robots and Systems. The paper is currently under review.We have submitted a journal article for drone audition to the IEEE/ACM Transactions on Audio Speech and Language Processing. Specifically, we proposed a noise covariance matrix estimation method that can be applied to sound source enhancement algorithms for drone audition. While this research is developed during Dr. Benjamin Yen's time at the University of Auckland, it is entirely within the research scope of the JSPS postdoctoral fellowship proposal and is a topic that will be further developed during this fellowship. The paper is currently under major revision.We have carried out a major outdoor experiment to collect the necessary data to perform performance evaluation for various drone audition algorithms. This includes accurate audio recordings of drone noise and a moving target sound source. In addition, accurate GPS data of the target sound source's movement is also recorded. These measurements will be helpful in evaluating sound source tracking performance from the algorithms proposed.We have planned a range of research topics related to the research theme to be researched by ourselves and new B4/masters students.
