Fov for one camera

Hardware ZED2
1

Hi, We are using zed 2i camera I coudn’t find fov of just one camera. there is no data for it in datasheet.

Hi @OnurS
Welcome to the Stereolabs forum.

What do you mean by fov of just one camera? The FoV of reported in the datasheet always refer to a single optic group

3

But when I calculate from image it is about 36 degree but datasheet is 70 for vertical? Am I missing a point?

4

How do you calculate it?

FoV is always available runtime with the ZED SDK: C++ / Python

Thanks for your reply. I am getting error get camera has no attribution v_fov

@OnurS please share your code so that we can check it.

zed = sl.Camera()
print(zed.get_camera_information().v_fov)

warning is belove

'pyzed.sl.CameraInformation' object has no attribute 'v_fov'
  File "C:\Users\onurs\Downloads\ball_tracking.py", line 161, in main
    print(zed.get_camera_information().v_fov)

AttributeError: 'pyzed.sl.CameraInformation' object has no attribute 'v_fov'

Here is the correct code (full version):

import pyzed.sl as sl


def main():
    # Create a Camera object
    zed = sl.Camera()

    # Create a InitParameters object and set configuration parameters
    init_params = sl.InitParameters()
    init_params.sdk_verbose = False

    # Open the camera
    err = zed.open(init_params)
    if err != sl.ERROR_CODE.SUCCESS:
        exit(1)

    # Get camera information (ZED serial number)
    zed_serial = zed.get_camera_information().serial_number
    print("ZED serial number: {0}".format(zed_serial))
    
    # Get camera information (Model)
    model = zed.get_camera_information().camera_model
    print(" * Model: {0}".format(model))
    
    # Get camera information (Resolution)
    w = zed.get_camera_information().camera_configuration.resolution.width
    h = zed.get_camera_information().camera_configuration.resolution.height
    print(" * Resolution: {0} x {1}".format(w,h))
    
    # Get camera information (Field of View)
    h_fov = zed.get_camera_information().camera_configuration.calibration_parameters.left_cam.h_fov
    v_fov = zed.get_camera_information().camera_configuration.calibration_parameters.left_cam.v_fov
    d_fov = zed.get_camera_information().camera_configuration.calibration_parameters.left_cam.d_fov
    print(" * Field of view: {0:.2f}° x {1:.2f}° - D: {2:.2f}°".format(h_fov,v_fov,d_fov))

    # Close the camera
    zed.close()

if __name__ == "__main__":
    main()

Expected output (with different FoV values):

ZED serial number: 35199186
 * Model: ZED 2i
 * Resolution: 1280 x 720
 * Field of view: 101.16° x 68.77° - D: 108.77°

Thanks for your reply. I get 41 and 68 which are close to my calculations. Your reply solve my problem thanks.
