Sensors from JSON and more #2821

ACLeighner · 2020-07-01T06:41:35Z

Proposing a few changes here:
-Added ability to load parameters for JSON for Barometer, Distance Sensor, IMU, GPS, Magnetometer
-Small change to python types doc, fixes a change I proposed before with better datatypes (float vs quaternion) for distance sensor
-Small change to documentation on linux build, sometimes deleting the 'binaries' and 'intermediate' folders in your unreal project after rebuilding airsim can fix errors where unreal tries to open content that doesnt exist anymore and causes the 'try rebuilding from source' error
-small change to move on path, replaces the position PID to use the velocity PID when traveling at constant altitude, elimnates shake problems

TODO:
-did not update documentation to show the new fields available for settings...

All CLA requirements met.

Great PR! Adding settings for all the sensors will be a great addition. Just a few comments -

Would be great if the indentation would be consistent, tabs and spaces are intermixed, will be better to use 4 spaces throughout
There's an open PR Distance sensor Upgrades #2807 which exposes the settings for Distance sensor, along with adding an option for drawing debug point like Lidar. It might be better to do all the Distance sensor changes in that PR since will make it easier to review and avoid merge conflicts

Probably unintentional change, should be reversed

Maybe add a line here regarding clean.sh which does all this

I don't see this being used anywhere?

yes, although relative pose is being consumed in the initialization of settings, it is not incorporated into the sensor model.

@ACLeighner can you either remove this setting or make the corresponding changes in the sensor model. (My guess would be you were in the middle of doing the same?)

Also, I'm not very sure about exposing each setting of the sensors such as noise, but if a user is modifying those, then they probably know what they're doing, so shouldn't be a problem. Though some explanation for all of them will need to be added

can you move the moveOnPath changes to a separate PR?
Can you share a test script to showcase this fixed the shaking issue?

@ACLeighner This branch now contains commits not related to the PR, cause its made from the master branch. It'll be best to create a new PR from the original commits using a separate branch if still interested in getting this feature in

jonyMarino · 2021-02-24T17:46:09Z

Hi @ACLeighner! Thanks for your contribution! I think it is time to merge it. Can you rebase your PR and solve the conflicts? Thanks!

This issue can be closed, its features have already been merged into master with commit 006d4e2.
