项目摘要
To employ the use of Visual Odometry (VO) and the Passive Thermal Imagery (TI) in order to tackle the fundamental problem of reliable and efficient camera based multi-target tracking systems. The aim is to produce a significantly more convenient solution that is capable of tracking and classifying targets between the ranges of sensors in the network. The main interference to the solution would arise from cloud and other obscurants, other problem would include varying illumination levels; this would be particularly significant should platforms wish to remain stealthy. Visual Odometry has been used in wide range of robotic applications that estimate the motion of an object from images taken at regular intervals. Due to advances in Plenoptic technology, it is likely that unison of visual Odometry and Plenoptic technology would outperform similar algorithms such as Simultaneous Localisation and Mapping (SLAM). As VO focuses on relative position(s) rather than mapping the terrain, there exists a possibility to enhance a baseline solution by the use of depth mapping. This therefore provides the possibility to create a sensor base network which can identify multiple targets and track their propagation throughout the network providing the backbone to an effective real time multi-target tracking solution. The challenge of varying illumination levels can be addressed by the use of passive thermal imagery - due to the fact TI detects an objects emittance rather than its reflection and so can be used at night. The use of TI is problematic as it would make the solution prone to low spatial resolution, history effects, variations in temperature, and low signal-to-noise ratios. This is an exciting challenge an excellent opportunity to develop new image processing methods for these particular types of sensors.The use of Deep Convolutional Neural Networks and Deep Q Learning has the potential to tackle the problem of reliable and efficient target recognition. In recent years deep learning has advanced to the point that real time object detection and classification have become feasible - even on relatively lacklustre machines. This means the combination of Deep Convolutional Neural Networks and LSTM techniques employed on the sensor network provides a possible solution to a multi-target tracking system.
使用视觉探光(VO)和被动热图像(TI)的使用,以解决可靠,高效的基于相机的多目标跟踪系统的基本问题。目的是产生一个更方便的解决方案,该解决方案能够在网络中的传感器范围之间跟踪和分类目标。对解决方案的主要干扰将来自云和其他晦涩的剂,其他问题将包括不同的照明水平。如果平台希望保持隐形,这将特别重要。视觉探测器已用于广泛的机器人应用中,这些应用程序估算了从定期拍摄的图像中估算物体的运动。由于元素技术的进步,视觉探光和元素技术的一致可能会优于类似的算法,例如同时定位和映射(SLAM)。由于VO专注于相对位置而不是映射地形,因此存在通过使用深度映射来增强基线解决方案的可能性。因此,这提供了创建传感器基网络的可能性,该网络可以识别多个目标并在整个网络中跟踪其传播,从而为有效的实时多目标跟踪解决方案提供了骨干。 通过使用被动热图像可以解决不同照明水平的挑战 - 由于TI检测到物体的散发而不是其反射,因此可以在晚上使用。 Ti的使用是有问题的,因为它会使溶液容易易于低空间分辨率,历史效应,温度变化和低信噪比。这是一个令人兴奋的挑战,是为这些特定类型的传感器开发新的图像处理方法的绝佳机会。对深度卷积神经网络和深度Q学习的使用有可能解决可靠有效的目标识别问题。近年来,深度学习已经发展到了实时对象检测和分类变得可行的地步 - 即使在相对乏味的机器上也是如此。这意味着传感器网络上使用的深卷卷神经网络和LSTM技术的结合为多目标跟踪系统提供了可能的解决方案。
