IWR6843AOP: How do I get the original point cloud data?

There is a parameter in the Visualizer GUI called Points, which is described as the number of points detected in the current frame. Here Points refers to the number of points contained in the detected person or all the points obtained by the sensor. What we want to get is all the point cloud data obtained by the sensor. If the Points here refers to the point cloud contained by the detected person, how do we get all the point cloud data?

Saving the Output

The output data from the mmWave sensor can be saved for future use in 2 ways: as a binary bitstream of the UART data, and as a csv file of the frame headers and TLVs.

To save either of these files, in oob_parser.py, set self.saveBinary and/or self.saveTextFile equal to 1, save the file, then run start the gui as described above. The output data will be recorded relative to the mmWave sensor, not rotated for world coordinates as the display is.

这里保存的点云是指被检测到的人员包含的点云还是所有的点云，因为我们发现在gui当中显示出的点云数量远超我们所保存的数据。我们想要保存全部的点云数据
