Asked 2021-Oct-10 at 04:04

I use vue3, when I create a project with vite, I import the roslibjs library and get an error using one of the functions, as shown below. But when I try to use vuecli to create a project, after importing the same library, everything is fine.

I'm not sure what Vue CLI + Webpack does differently for roslib to work in the browser.

However, in the browser, you should use the pre-built versions of roslib (where the Node-specific constructs are transpiled away) per the docs:

If you use roslib in a browser, all the classes will be exported to a global variable called ROSLIB. If you use nodejs, this is the variable you get when you require('roslib')

Import the roslib/build/roslib.js script, which sets window.ROSLIB:

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:

Displaying rgb8 pixel data in-browser

Asked 2020-Jan-09 at 00:11

I have found similar questions to mine on SO, but have not yet come across an answer to this problem. I have a rgb8 encoded image that I am trying to display in-browser, either in an img or canvas element. I am unsure how to convert this pixel data into an image properly, and was looking for any insight.

For context, the source of this rgb8 data is from a ROS topic with type sensor_msgs/Image. When subscribing to this topic using roslibjs, I am given the following object:
