什么运动跟踪传感器能跟踪多个对象？

尝试使用panasonic的Grideye：AMG8833



以下为原文

        Try using the Grideye by panasonic: AMG8833

他们到底追踪的是什么？
它可以通过IR跟踪吗？
为什么有种范围或者有多近或远近？



以下为原文

        What exactly are they tracking the motion of?  Is it something that can be tracked through IR?  Why kind of range or how close or far away?

他们希望有大约20'的射程。
从我收集的内容来看，它适用于某种安全系统，有点像安全摄像头，但它会在没有图像的情况下进行跟踪。
所以他们会跟踪走进商店的人。



以下为原文

        They would like to have about 20’ of range.  From what I gather it is for some sort of security system, somewhat like a security camera but it will track without the image. So they will be tracking people walking in and out of a store.

他们应该为这个应用程序查看飞行时间相机。
TOF不仅会检测到你在视野中，而且它会跟随你并检测你是直接进入相机还是移动相机的L-R或R-L。
他们使用这些相机进行跟随您的广告或适合您身体的衣服，这样您就可以在不尝试任何操作的情况下看到它。
以下是Bluetechnix GmbH的一个版本：
零件号150-3001-1



以下为原文

        Travis,
They should be looking at a Time of Flight camera for this application. TOF will not only detect that you’re in the field of view but it will follow you and detect if you’re coming straight at the camera or moving L-R or R-L of the camera. They use these cameras for advertising that follows you or clothing that adjusts to your body so you can see it without trying anything on.
Here is one version from Bluetechnix GmbH:
Part Number 150-3001-1

如果他们使用Acconeer的A111，他们可以从左到右跟踪。
为它设置了一个演示应用程序。
他们使用雷达，有大约2米的范围。
产品亮点页面 
XC112 
XR112
他们现在还有一个新的评估套件，以及XR112和XC112  - 高亮页面上的入门视频。
Acconeer做了一个项目，他们用2个A111传感器在一个电源点上移动页面，它可以从左到右跟踪。
不同的应用，但我知道它可以做到这一点。



以下为原文

        If they use the A111 from Acconeer they can track from left to right.  There is a demo application set up for it.  They use radar, have about a 2 meter range.
Product Highlight Page
XC112
XR112
They have a new eval kit for it now as well with the XR112 and XC112 - Getting started video on the highlight page.  Acconeer did a project where they moved pages on a power point with the 2 A111 sensors and it could track left to right.  Different application but I know it can do this.

我试图找到视频和从左到右动作的文件将在我有更多时回发。
已经给了我们用于传感器展览的一些文件，但是想在论坛上发帖之前与Acconeer谈论这个。



以下为原文

        I am trying to find the video and files that did the left to right motion will post back when I have more.  Had been given some files that we used for a sensor expo but wanted to speak with Acconeer about this before posting on the forum.

抛出的另一个选择是Melexis红外32x24像素阵列，如MLX90640ESF-BAB-000-TU-ND和MLX90640ESF-BAA-000-SP-ND。
这些类似于Panasonic GridEye产品，除了相当高的分辨率。
如果他们想要更高的分辨率，他们需要看一些类似FLIR产品的东西，比如这些。
但是，所有这些传感器都可以识别出比环境温度更高的像素。
必须编写软件以执行对该信息有用的任何操作。
正如Ben指出的那样，这是一个非常难以解决的问题。
如果他们试图确定进入房间的人数是否全部离开，他们可能会失败。



以下为原文

        Another option to throw out there is the Melexis Infrared 32x24 pixel arrays, such as the MLX90640ESF-BAB-000-TU-ND and the MLX90640ESF-BAA-000-SP-ND.  These are similar to the Panasonic GridEye product, except quite a bit higher resolution.  If they want to go still higher resolution, they would need to look at something like the FLIR products, such as these.  However, all these sensors can do is identify warmer-than-ambient pixels.  Software must be written to do anything useful with that information.
As Ben points out, this is a very hard problem to solve.  If they are trying to determine whether the number of people who have entered a room have all left, they will likely fail.

德州仪器（TI）提供的雷达（mmWave），在这种情况下是汽车，部分是为了保护行人免受自动驾驶车辆的影响。
当这些物体穿过远处的路径时，它可以跟踪多个目标甚至跟踪它们的轨迹。

演示视频：
如果由于学习曲线，这只是一次性申请中的一部分，那就太过分了，不建议使用，但如果他们进入计算业务的人员那将是非常有效的。



以下为原文

        The radar available from Texas Instruments, mmWave, in this case automotive, is made in part to protect pedestrians from autonomous vehicles. It can track multiple targets and even follow their trajectory when those objects cross paths in the distance.

It’s overkill and wouldn’t be recommended if this is just one part in a 1 off application because of the learning curve, but if they’re going into the people counting business it would be extremely effective.
