Problems running photo sample on Sphinx

ANAFI Ai
1

I already reported here a problem with a remote Sphinx instance (see last post). These warnings are still there.

Today I tried to get familiar with taking photos and tried this sample olympe/src/olympe/doc/examples/photo.py at 324a4b2744f6f024a2f0a3dfab2ddddb58b4566c · Parrot-Developers/olympe · GitHub by changing the drone IP to the IP of my Sphinx instance.

The problem with the missing or failing index manifests again. The assertion fails after a 60 s timeout:

This is a warning/error I’m seeing all the time at startup:

The script shows the same problems if run directly on simulator

Could somebody of the knowing please try to answer/comment?

TIA

I’m not even able to make a photo, neither on simulator, nor on Anafi.

This is the code:

# Setup
self.drone(camera.set_camera_mode(cam_id=0, value='photo')).wait()

self.drone(camera.set_photo_mode(
                cam_id=0,
                mode='single',
                format='full_frame',
                file_format='jpeg',
                burst='burst_4_over_1s',
                bracketing='preset_1ev',
                capture_interval=0
)).wait()

Shoot:

        self.logger.info("taking photo")
        photo_saved = self.drone(camera.photo_progress(result="photo_saved", _policy="wait"))
        self.drone(camera.take_photo(cam_id=0)).wait()
        if not photo_saved.wait(_timeout=30).success():
            assert False, "take_photo timedout"

It always runs into timeout when trying to make the photo. On simulator the mode change between video and photo is visible in the front camera simulation (different FOV)

I was using your sample code for this. What am I making wrong here?

Having now tested the sample provided here Get real-time photos from the Anafi in sphinx - #2 by ndessart

It is a bit outdated, but I could make it work against a real drone.

Running this script either remotely against or locally on the simulator does not work and shows the same error symptoms:

The script (when run on simulator):

At least some hints here:

Seems, photo is a bit “underexposed” in simulator…

Hi. The example in the code does have some problems, however, I took photos in a different way. You can use the following command to extract a photo sphinx-cli camera front_streaming -n --count=1 -o . (details can be found here Record and visualize cameras - 2.8.2 ). If you want to call this command with code, you can try the OS library. Hope to help you.
