相机that track their environment are only a couple of years old. As far back as 15-years ago, you would’ve had to manually program your own camera to do something as trivial as color-recognition.
But over the past couple of years, the need for cameras that can cooperate and communicate with other electronics has skyrocketed alongside the popularity of drones and similar robotics. By tracking visual features within the cameras environment, these next-gen cameras are capable of guiding robotics through various spaces with a high degree of accuracy.
英特尔RealSense T265网络摄像头
挑选你将使用机器人学的相机是一个比摘相拍摄相机的速度不同。因为如果机器应该查看相机进行数据，那么您可能想要构建相机，以不同于它对人类感知的方式看世界。
英特尔的RealSense技术应该帮助重塑我们与我们的设备互动的方式，更重要的是，我们的设备与周围世界的互动方式。那是因为它允许机器更好地了解，互动，甚至从周围的环境中学习。当然，不同的机器将具有不同的深度感测需求。有些人在距离距离望远下，其他人几乎不需要看到几英寸未来。
The RealSense is for use in drones, robotics, and other similar installations. Because theT265is a tracking camera that uses a small form factor alongside some low power consumption. It’s supposed to provide the kind of tracking support that people want without detailed configuration required, right off the shelf. Sort of a plug and play solution, you could say.
Things to Keep in Mind
RealSense cameras are usually pretty easy to pick between. The D-series are often favorites for people who are looking for something that can work out of the box. That’s mostly because they’re supported with higher frame rates, stronger resolutions, and an overall greater RGB quality. So for someone who really can’t skimp on any of the essential elements of strong cam performance, that’s clearly a lot of strengths.
But the T265 is a bit of an exception to the longstanding trend of ease-of-use favoring the D-series. It offers basically everything you might otherwise want from the D-series, except in a much more modern format, and in a way that’s much more approachable for novice users.
And though approachable for novices, the T265 still brings to the table a full range of developer access options, allowing you to easier integrate the camera into the platform of your choice. That include support for Linux, Windows, and MacOS.
此外，可以使用Python，node.js，c ++和其他人来操纵RealSense SDK。它还与Matlab，PCL，Unity以及各种发展技术融为一体。你几乎可以作为普遍支持。
Design & Layout
The T265 measures 1 x 4.3 x 0.5 inches, with a body that closely resembles the body-type of most Logitech webcams. It’s got an elongated build that looks like it would be quite comfortable sitting atop basically any PC. The camera measures about two ounces, so the featherweight design is quite good for taking from place to place, as may be the case when using a laptop or similar portable device alongside the T265 Webcam.
此外，T265是用跨平台支持制作的，使其成为开发人员友好的设计，允许在无人机和类似机器人中定位和映射。这使得增强现实映射，原型化和类似的项目更容易。
由于它重量很少，大约两盎司，相机不会重视你的原型。即使您使用较重的包含配件。谈到包含的附件，英特尔RealSense T265网络摄像头包括一对鱼眼镜透镜传感器，可以在默认镜头上轻松交换。
Internally, you’ll find this RealSense cam supports its own IMU and VPU, which are there to operate the v-slam algorithm. Since you’re getting computing power out of the camera itself, that helps enable very low latency in all your interactions with the device. It also makes things less computationally intensive for the other components within your system.
If you’re not familiar with SLAM, it’s the simultaneous localization and mapping technology behind the T265. It’s supposed to help a device construct and update an increasingly accurate map of a previously unknown environment. The T265 uses the latest iterations of this technology, and alongside USB 3.1 support, it’s pretty clear they intend to have this firmware continue to be updatable into the distant future.
Like basically any modern RealSense camera, the T265 is capable of tracking its own location inside of the environment which it is mapping. That kind of mechanical self-awareness can be either very useful or absolutely essential, depending on the sort of tasks you have in mind for the T265. Someone who’s trying to survey a wooded area will definitely want something like the T265 to help them along. Because the camera is capable of being smart enough to not fly head-on into a tree. But how about using this so-called webcam when you’re working with a more involved and hands-on problem?
跟踪方法
Long ago, years before GPS was something we could rely on, sailors would do their navigation by following the stars in the sky. That’s because with the help of some objects at a fixed distance, it’s possible to track motion. The Intel RealSense T265 Webcam makes use of multiple cameras to help it develop a better sense of depth perception, and in turn giving it a much strong ability to work through an environment safely.
Since it uses two eyes, the T265 is actually a little bit like human sight. Of course, unlike human sight, the V-slam is also incorporating a bunch of inertial measurements captured by other sensors within the camera. So the T265 doesn’t navigate in isn’t exactly the same way as sailors used to do it, but the fundamental principles are still the same. It sights an object and uses to help better understand the environment around it as it continues to navigate through the world.
RealSense Vision处理器是利用各种不同的先进算法来处理图像数据，这是一个允许它来计算高分辨率3D地图，基本上实时计算。这可能是可能的，无需专用的主处理器甚至是专用GPU，这允许您的系统释放其他任务的带宽。
如果你知道你在做什么，可以让这台相机做一些非常令人印象深刻的事情。特别是如果您决定将其放置，以帮助自动化其特征。但是，真的，天空是谈到真正的相机时的极限，因为你正在使用开源平台。
如果您不熟悉开源软件的所有开源软件，则允许任何人和每个人都允许查看构建此设备的代码。不仅要查看它，而且根据需要进行交互并更改它。至少，只要你知道你在软件上的方式。
But an open source design isn’t only attractive to coders, it’s actually attractive to novice users as well. Because it means you can make use of kits created by other developers and deploy them on your own gear. There are also some privacy advantages of open source software. You don’t have to worry about your camera being used as spyware against you, for instance.
其他考虑因素
作为公司，英特尔几乎不需要任何介绍。您通常可以相信他们所做的内容，您可以相信他们来解决他们的错误，并且您可以信任他们合理的客户服务。
The only real complaint someone might have with this camera is the price. Because Intel has this market somewhat cornered, they’re allowed to command slightly above-average prices for cameras like the T265. Of course, there’s nothing wrong with paying for the best, especially if you’re going to be able to save some time in the process. And the T265 is nothing if not a timesaver.
Who Should Choose the Intel Realsense T265 Webcam?
这是一点strange that Intel decided to call this a webcam. It has the superficial appearance of a webcam, and it’s a camera, but that’s really where the similarities come to a close. Everything about this camera is focused on the fact it’s a RealSense device. From the physical form factor of the device to the software it supports, nothing about this screams webcam. Apart from the appearance.
How well the T265 will work for your particular application at least partially depends on you. There’s no one-size fits all kind of solution for a RealSense webcam, and maybe you really will end up using it as a webcam. But the T265 certainly does have its own well defined niche. And someone who’s looking for the most basic and simple camera they can possibly get their hands on will not be well served by the T265.
因为这件事是合理加载的选择和添加功能。在可交换镜头和羽量级设计之间，T265肯定可以访问很多不同类型的人员上的大量不同类型的项目。虽然您可以使用此摄像头可以做的深入定制，但比您可以与他人的定制更好，但它也不会更糟糕。
All in all, for people who are looking for a plug-and-play RealSense camera, theT265 will probably work quite well. It’s incredibly lightweight. It’s easy to install and configure, and the webcam itself will do most of the heavy lifting when it comes to mapping and topography. If the price doesn’t scare you off, this thing shouldn’t be a source of disappointment.
