Procam transparent correspondence

数据投影仪是一种常用的显示设备，用于教室，会议室，甚至家庭娱乐系统。一些更先进的数据投影仪包括嵌入式摄像机，它提供了与投影场景交互的能力。这些系统被称为投影摄像机，或PROCAM系统。****这个项目的目标是开发方法来建立投影图像和从相机获取的图像之间的对应关系。特别是，这些对应关系必须透明地建立，而不会以任何可察觉的方式改变投影图像的内容。为了解决这一问题，本项目将研究校准、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，以推进该领域的知识。****一旦解决并演示，PROCAM系统功能将导致使用数据投影仪的新的和不同的方式，特别是在高级增强现实应用中。例如，更高层次的交互将成为可能，因为在场景中感知人类将变得简单得多，即使他们在投影图像的前面。此外，投影仪将能够感知场景的深度，使其能够充当距离传感器。****加拿大最终将在声誉上受益，因为我们有能力继续创新，在经济上受益，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.**********
