Procam transparent correspondence

数据投影仪是教室、会议室甚至家庭娱乐系统中使用的常见显示设备。一些更先进的数据投影仪包括嵌入式摄像头，提供与投影场景交互的能力。这些被称为投影机相机，或PROCAM系统。* 本项目的目标是开发在投影图像和从相机获取的图像之间建立对应关系的方法。特别地，这些对应关系将被透明地建立，而不会以任何可感知的方式改变投影图像的内容。为了解决这一问题，本项目将研究定标、立体匹配、隐写和辐射传递函数四个子问题。这些子问题中的每一个都需要开发新的解决方案，以促进该领域的知识。一旦解决和演示，PROCAM系统的功能将导致新的和不同的方式来使用数据投影仪，特别是在先进的增强现实应用。例如，更高级别的交互将是可能的，因为在场景中感知人类将简单得多，即使他们在投影图像的前面。此外，投影机将能够感知场景中的深度，使其能够充当范围传感器。* 加拿大最终将受益于声誉，因为我们有能力继续创新，经济上，因为我们分享了这项工作产生的下游产品的经济利益。

Data projectors are a common display device used in classrooms, board rooms, and even home entertainment systems. Some of the more advanced data projectors include embedded cameras, that provide some ability to interact with the projected scene. These are known as projector-camera, or PROCAM systems. ****The goal of this project is to develop methods to establish correspondences between the projected image and the image acquired from a camera. In particular, these correspondences are to be established transparently, without changing the content of the projected image in any perceptible way. In order to solve this problem, the project will investigate the four sub problems of calibration, stereo matching, steganography, and the radiometric transfer function. Each of these sub problems will require novel solutions to be developed that will advance knowledge in the field.****Once solved and demonstrated, PROCAM system functionality will lead to new and different ways to use data projectors, especially in advanced Augmented Reality applications. For example, a much greater level of interaction will be possible, as it will be far simpler to perceive humans in the scene, even when they are in front of the projected image. Also, the projector will be able to sense depth in the scene, allowing it to serve as a range sensor. ****Canada will ultimately benefit both reputationally, for our ability to continue to innovate, and economically, as we share in the financial benefits of the downstream products stemming from this work.**********
