Our company want to make a bathroom fall detection product for smart homes as soon as possible. We found that the "Very Fine Motion Detection vs PIR" tutorial from Texas Instruments says that the following behaviors are identified using the IWR1443 and IWR1642 respectively.
For this tutorial I have the following questions:
1. Which mmWave radar IWR1443 or IWR1642 should I use for bathroom falls detection?
2. The tutorial “Very Fine Motion Detection vs. PIR” contains information about people's behaviors such as walking, standing, arm movements, typing, and breathing. Does thie demo can do the people fall detection? If not, can fall detection be done with simple modifications? Do you have any suggestion for this modification?
3. For our fall detection requirements scenario, should we purchase that development board to develop IWR1642-DATA-CAPTURE-BNDL or IWR1642BOOST? What's the difference between this DATA-CAPTURE-BNDL and BOOST? Does it mean that if we do not purchase the DCA1000EVM there is no way to modify the SDK and algorithms?
4. I also found out that there is a demo for People Counting User's Guide (http://dev.ti.com/tirex/#/?link=Software%2FmmWave%20Sensors%2FIndustrial%20Toolbox%2FLabs%2FPeople%20Counting%20Demo)
So what do we do to do fall detection based on the demo of this people counting? Or is it based on the demo of Very Fine Motion Detection? That is faster and we hope to introduce prototype products as soon as possible.
Hi Weisen,
The answers are listed below:
1. Does the mmWave SDK 1.1 Out-of-Box Demo can get elevation of each person?
Yes, Out-of-Box Demo can get elevation information of each object.
2. Does the mmWave SDK 1.1 Out-of-Box Demo can get 3D point could of each person? Do we need to further segment of each human?
Yes, Out-of-Box Demo can get 3D point could for each object. Here's some demo show video link you can refer.
3. We don’t need buy the DCA1000. Because we use the mmWave SDK 1.1. we don’t do any modify of SDK. We don’t use the ADC RAW data. Is this understanding correct?
Yes, if you don't want to get the ADC RAW DATA, you didn't need to but DCA1000
4. The function of DCA1000 is get the raw data? If we want design the algorithm form from scratch in the future, we need buy the DCA1000. For current condition, my question is for this fall detection prototype do we need buy the DCA1000?
Yes, if you want to base on point cloud, and do some high level algorithm to identify if people is fall or not. You don't need DCA1000. If you want to improve the point cloud, you may need the DCA1000 to capture the ADC RAW data.
