How to change resolution?

[Goughhhhhh]

How to change the default camera resolution of 1280×480? I want to set it to 640×480

Hello,

to change the resolution of your camera, you can use the Region of Interest feature of the sensor.
This feature is explained here: https://docs.prophesee.ai/stable/hw/manuals/pixel_selection/region_of_interest.html

In the case of ROS wrapper, you can call this feature (facility) on the "camera" object simarly to what we do for biases in:
https://github.com/prophesee-ai/prophesee_ros_wrapper/blob/master/prophesee_ros_driver/src/prophesee_ros_publisher.cpp#L80

camera_.get_facility<Metavision::I_LL_Biases>().load_from_file(biases_file_);

In the case of ROI, you would do something like:

Metavision::I_ROI::Window roi_to_set(320,0,640,480);
camera_.get_facility<Metavision::I_ROI>().set_window(roi_to_set);
camera_.get_facility<Metavision::I_ROI>().enable(true);

Hope this helps,

Thank you for your response and for providing the two methods to set the resolution of the event camera. I’m currently trying to implement the ROS wrapper approach. Could you please provide more detailed instructions or examples on how to set it up? Any specific steps or code snippets would be really helpful. Thank you for your assistance!
