Tool/software: Code Composer Studio
Hi,
I have a project requirement as below.
My application should able to track a person and need to identify fall detection of that person using 68xx sensor.
I have explored in TI forums and got some information about fall detection (http://dev.ti.com/tirex/explore/node?node=AFmsC4Pjv3N8OtdrcDLsEg__VLyFKFf__LATEST&search=mmWave%20industrial%20toolbox)
- Using 68xx ISK-ODS, point cloud data of a person will be retrieved.
- With the point cloud data, user has to calculate height of the person and dimensions of the target.
- Then fall detection algorithm will be applied using height & dimension of the target.
My problem is that how to identify height of the person dynamically using point cloud data. I agreed forum had given separate experiment for Height detection of an object (http://dev.ti.com/tirex/explore/node?node=AEt9MlQKWTNSH9wjSD.VTA__VLyFKFf__LATEST&search=mmWave%20industrial%20toolbox). But I would still need clarification and support for the formula given.
Formula:
Estimated Height = Distance to ground - (Distance from EVM - 8cm bias).
Queries:
- I assume Distance from EVM can be achieved using out of box demo. But want to know how to calculate Distance from ground value?
- In forum Bias value is mentioned as 8 cm. But I assume that this value is dependent on height of a person and placement of the sensor. If so, How to arrive this bias value dynamically?
- What is formula to get dimension of a target for fall detection ?
- Currently having 68xx ISK ES2.0 and 68xx ISK ODS ES1.0. Please let us know, if the hardware doesn’t have support?
Please share the formula which would be compatible for 68xx ISK and 68xx ISK - ODS
Looking forward your response.
Thanks!
Regards,
Vivek
