Hello.
Is it possible to recommend how to extract parameters from ZED_explorer and apply them to the wrapper configuration?
I tried to apply visible parameters as: saturation, sharpness, gamma,turn white_balance and exposure to auto and use the same denoising and exp. compensation but the picture is still different. A lot of noise in the picture.
ros2_wrapper
zedxm.yaml
video:
exposure_time: 16666
auto_exposure_time_range_min: 28
auto_exposure_time_range_max: 16666
exposure_compensation: 50
analog_gain: 8000
auto_analog_gain_range_min: 1000
auto_analog_gain_range_max: 16000
digital_gain: 128
auto_digital_gain_range_max: 256
denoising: 50
common-stereo.yaml
saturation: 4
sharpness: 1
gamma: 6
auto_exposure_gain: true
exposure: 100
gain: 97
auto_whitebalance: true
whitebalance_temperature: 42
enable_24bit_output: false
publish_rgb: false
publish_left_right: true
publish_raw: false
publish_gray: false
publish_stereo: false
I also tried to change the gamma to 2; the noise was lower, but the image was darker.
And I would prefer a setting with auto configuration. No one canceled the day.
Once again. ZED_Explorer can show a good picture, I need it in ros2_wrapper. Help me with it, please.
I really appreciate any help you can provide.

Hi @sergii Stereolabs community.
You must perform this manually.
Please take a screenshot of the Camera Settings in ZED Explorer and share it here. I will help you set up the ROS 2 Wrapper the same.

Hello Myzhar,
Here is my screenshot with the current settings from ZED_Explorer
I tried to apply these parameters, but I think there must be something else that can affect quality.

Please enable Camera Control debug information:
thread_sensor_priority: 70 # ONLY with 'SCHED_FIFO' and 'SCHED_RR' - [1 (LOW) z-> 99 (HIGH)] - NOTE: 'sudo' required
thread_pointcloud_priority: 60 # ONLY with 'SCHED_FIFO' and 'SCHED_RR' - [1 (LOW) z-> 99 (HIGH)] - NOTE: 'sudo' required
debug:
sdk_verbose: 1 # Set the verbose level of the ZED SDK
sdk_verbose_log_file: '' # Path to the file where the ZED SDK will log its messages. If empty, no file will be created. The log level can be set using the `sdk_verbose` parameter.
use_pub_timestamps: false # Use the current ROS time for the message timestamp instead of the camera timestamp. This is useful to test data communication latency.
debug_common: false
debug_sim: false
debug_video_depth: false
debug_camera_controls: false
debug_point_cloud: false
debug_positional_tracking: false
debug_gnss: false
debug_sensors: false
debug_mapping: false
debug_terrain_mapping: false
debug_object_detection: false
debug_body_tracking: false
debug_roi: false
debug_streaming: false
Then, copy and paste here the full node log to allow me to check that everything goes as expected.
