e_disparity_not_allowed
madratman opened this issue · 3 comments
I've been getting this error for a couple of days now. Unable to debug.
Running via guidance sdk work fine, but I get this via the ros wrapper:
$ rosrun guidance guidanceNode
llibusb_get_device_list ret = 10 !!!
Waiting for board ready...

The calib params are also quite different from what I got earlier https://github.com/dji-sdk/Guidance-SDK-ROS/blob/master/calibration_files/camera_params_left.yaml
The difference is this time I calibrated it with the drone, and earlier I was calibrating without the drone.
Edit: Yeah, I just recalibrated without the drone using the DIY mode and it works. Calibrating with the drone is leading to the above error.
Dear sir,
What was the work type you selected? Please select DIY type.

Also getting an e_disparity_not_allowed error
Current status is that I have not calibrated. Would we expect this error to exist prior to calibration?
Due to this error, I am unable to proceed with calibration in ROS as documented here https://github.com/dji-sdk/Guidance-SDK-ROS#using-ros-tools-for-calibration-and-stereo-processing
Because I get the error while trying to run the guidanceNodeCalibration node

I will attempt to do the calibration in Windows? Any other ideas would be appreciated
@madratman Seems like you might be one to know? Would appreciate your "Guidance"! :)
Edit to above:
I no longer have this error after going through Guidance Assistant on Windows. It seems running Guidance Assistant, enabling the USB API, choosing which depth images to push over USB (up to 2) , etc, is required
