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.
