Hi, there.
I used IWR6843ISK EVM, flash memory for pplcount_lab_xwr68xx.bin(C:\ti\mmwave_industrial_toolbox_4_1_0\labs\people_counting\68xx_people_counting\prebuilt_binaries) firmware.I want to use STM32 chip combined with IWR6843ISK EVM to realize the function of counting the number of people in and out.Here are my questions:
1. When I used the pplcount_gui.exe GUI program(C:\ti\mmwave_industrial_toolbox_4_1_0\labs\people_counting \68xx_people_counting\gui) to observe the target, I found that when two people walked into the detection area one by one, EVM would sometimes judge it as a person.
May I ask why?What factors will affect EVM's judgment of the number of people in the current region?
Is there a way to improve this function?
Or can you adjust which parameter makes the judgment more accurate?
2. When the distance between two people is about 1 meter or more, the area can be clearly identified as two people.
Are there only two people separated by more than one meter?
3. When I observed the target with the pplcount_gui.exe GUI program, I found that when two people moved in the area, the small colored circle representing the target in the observation window would suddenly grow larger and disappear. May I ask why?
4. When I observed the target with the pplcount_gui.exe GUI program, I found that when two people moved in the area, the number of people beside the observation window was 1. There was a small colored circle representing the target moving and its moving trajectory, and behind it there was a small black dot, which should be the point cloud data of the second target.
May I ask why the second target is only point cloud data, but will not be detected as human?
5. When two people move in the area, check the data of data serial port and find two situations.
a. The number of TLV in the frame header is 1, which is the point cloud TLV (0x06), but there is no target list TLV (0x07) and target index TLV (0x08), so that two people cannot be detected.
b. The TLV number of frame header is 2, which is the point cloud TLV (0x06) and the target list TLV (0x07), while there is no target index TLV (0x08). The first target number in the target list TLV belongs to the normal range, which is between 0-249, and the other number is super large, reaching 65532, with no rules.
I wonder if it is the anomaly of these two types of data that affects the EVM's judgment of the number of people in the current region?
Is there any way to remove these two kinds of abnormal data?
Due to the time difference between us, it will take a long time to get the reply, so I have a lot of questions, please forgive me.
Hope to get your help, thanks a lot.
