DESCRIPTION (provided by applicant): The primary objective of this SBIR project is to develop a complete wide area thermal imaging system for rapid SARS screen. Although general-purpose thermal imaging systems offer many distinct advantages for this application, there are several variables that can affect the accuracy of non-contact human body temperature measurement. These variables are capable of producing both false positive and false negative readings without any outward indication that the data are flawed. Therefore, in the Phase I project, we will be focus on investigating characteristics of thermal image sensors and variables that can significantly affect accurate of skin temperature measurement. Proof of concept hardware and software systems will be developed and tested with optimal selection of components and parameters. Specifically, our Phase I objectives are listed below: Aim 1: Evaluate two thermal imaging IR technologies to identify suitable sensor and improvement techniques for SARS screening applications. Aim 2: Extensive experimental study to characterize potential environmental error sources. Aim 3: Develop a proof of concept thermal imaging hardware/software system to demonstrate the feasibility of skin temperature screening. Aim 4: Develop a proof of concept system to demonstrate the feasibility of face detection using OmniEye video camera and an integrated face tracking using a thermal image sensor. Aim 5: Prepare for Phase II work plan. In the follow-on Phase II project, we will design and build fully function thermal imaging system with OmniEye Pan-tile platform that is optimized for SARS screening applications. We will develop and test fully functional software for thermal image analysis, face finding and tracking, and alarm. We will perform extensive tests to validate the functionality and performance level of the system.

描述（由申请人提供）： 该SBIR项目的主要目标是开发一个完整的广域热成像系统，用于快速筛查SARS。虽然通用热成像系统为该应用提供了许多独特的优势，但有几个变量会影响非接触式人体温度测量的准确性。这些变量能够产生假阳性和假阴性读数，而没有任何外部迹象表明数据有缺陷。因此，在第一阶段项目中，我们将重点研究热图像传感器的特性和可能显著影响皮肤温度测量准确性的变量。将开发和测试概念验证硬件和软件系统，并选择最佳组件和参数。 具体而言，我们的第一阶段目标如下： 目的1：评估两种红外热成像技术，以确定合适的传感器和SARS筛查应用的改进技术。 目的2：广泛的实验研究，以表征潜在的环境误差源。 目标3：开发概念热成像硬件/软件系统的证明，以证明皮肤温度筛查的可行性。 目标4：开发一个概念验证系统，以证明使用OmniEye摄像机进行人脸检测和使用热图像传感器进行集成人脸跟踪的可行性。 目标5：编制第二阶段工作计划。 在后续的第二阶段项目中，我们将设计和构建功能齐全的热成像系统，并采用针对SARS筛查应用进行优化的OmniEye Pan-tile平台。我们将开发和测试功能齐全的软件，用于热图像分析、人脸识别和跟踪以及报警。我们将进行广泛的测试，以验证系统的功能和性能水平。
