Decoding ROS messages from ROSBrdidge

QUESTION

Decoding ROS messages from ROSBrdidge

Asked 2021-Sep-28 at 09:25

How can I decode rosbridge data in the browser?

So far ive been able to decode the following types:

Uncompressed raw RGB
Uncompressed raw Depth
JPEG compressed RGB

My Problem now is decoding compressed depth and PointCloud2 data. As far as my understanding goes, the data is encoded as base64. The depth image has been compressed to a mono16 PNG. I have tried many different approaches, but none seem to work. The depth image is supposed to contain 307200 depth values of 16 bits each.

I do not want to display this data in something like ros3djs or webviz (cloud not figure out how they do the decoding). I want to decode the data and use it in my own analysis.

Steps to reproduce:

Here is a sample file. It contains the data field of the JSON message: https://drive.google.com/file/d/18ZPpWrH9TKtPBbevfGdceZVpmmkiP4bh/view?usp=sharing

Make sure you have a device publising or a rosbag playing
roslaunch rosbridge_server rosbridge_websocket.launch
Launch your web page and make sure you added roslibjs in your script tag

The JS of my web page is simplified to this:
