你好
我正在使用AWR1642 + DCA1000EVM
打算要提取出point cloud data
我參考了industrial toolbox 的demo
在ROS顯示出了point cloud
但似乎只能save config?
感謝您
Wesley He:
你好,
提取点云请参考以下信息。
The data saved in this file is the exact same data and format that is transmitted out of the mmWave device over the DATA_port. Users should see the mmWave demo doxygen in the mmWave SDK package to understand the format of the data and how to parse it.
To process the recorded data: See the Visualizer User's Guide, section 4.4, to understand what the data contains. Information on the actual data is available in the doxygen – <mmWave_SDK_Install_DIR>\packages\ti\demo\xwr16xx\mmw\docs\doxygen\html\index.html.
User's Guide: www.ti.com/…/swru529a.pdf
There is a demo in beta that saves the recorded data to a human readable CSV file – you can read the code and understand the data conversion process:
mmWave visualizer with the LOG function: dev.ti.com/…/
• Data format description of UART data for mmWave Demo.
• SDK01.00.00.05:
• SDK01.01.00.02: Section "Output information sent to host" file:///C:/ti/mmwave_sdk_01_01_00_02/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html
• SDK01.02.00.05: Section "Output information sent to host" file:///C:/ti/mmwave_sdk_01_02_00_05/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html
• SDK02.00.00.04: Section "Output information sent to host" file:///C:/ti/mmwave_sdk_02_00_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html

回复 Wesley He:
你好,
根據你的回覆以及操作結果,我的理解是:
mmWave visualizer with the LOG function 輸出是grouped後的object points(.csv)若要取得還未grouped 的cloud points,需要了解mmwave設備輸出的Data format
可經由mmWave visualizer with the LOG function的source code了解資料封包型態,以及grouped的過程ROS確實無法dump出point cloud.
以上三點為我的理解,請問是否有誤?
感謝

你好,
我閱讀了dev.ti.com/…/mmWave_Demo_Visualizer csv (中間,輸出csv的版本)
其中的兩份代碼:
mmWave_Demo_Visualizer_Record/app/mmWave.js
mmWave_Demo_Visualizer_Record/components/ti-widget-streamsaver/StreamSaver.js
由於我對javascript code並沒有研究,只能大致猜測以下應該是在save csv file的部分(不過我並沒找到save csv 之類的key words)
(圖一)
我只看到代碼中在進行data format decode,並沒有發現有在做point clouds->grouped object points
根據下圖,我認為grouping/clustering 應該無法經由demo visualizer dump出來
(圖二)
應該只能經由DCA1000EVM or ROS software,又應該要如何取出?
感謝

你好,
ROSdemo与网页版visualizer得到的数据是一致的,都没有做高级的grouping。CSV得到的数据与LINUX界面显示的一致。
谢谢。
