Hi, Im trying to calibrate my cameras OAK system with the OAK-D-SR board and two OV9282 lens. The position of the elements is shown below.

Then, I configured the json file as follow:

{

"board_config": {

"name": "OAK-D-SR-MOD",

"revision": "R0M0E0",

"cameras": {

"CAM_B": {

"name": "left",

"hfov": 71.86,

"type": "mono",

"extrinsics": {

"to_cam": "CAM_C",

"specTranslation": {

"x": 0,

"y": 2,

"z": 0

},

"rotation": {

"r": 0,

"p": 0,

"y": 180

}

}

},

"CAM_C": {

"name": "right",

"hfov": 71.86,

"type": "mono"

}

},

"stereo_config": {

"left_cam": "CAM_B",

"right_cam": "CAM_C"

}

}

}

However, I always received "The high epipolar error between" message after calibration processes. Did I misunderstand some information from calibration tutorial? Please help.

Thanks for your support.

    The config json is likely fine. The issue is probably the calibration procedure. A high epipolar error would suggest that there were some inaccuracies when measuring the marker sizes / the images were blurry / overexposed...

    Can you show some images from the dataset? Best to redo the calibration.

    Thanks,
