I can see the video stream from the stereo fisheye cameras and the position of it, so the setup worked well with the product. My problem is, I would like to include computer vision algorithms for my application, so I need the the camera calibration files of the T265. I know that this camera is previously calibrated, but for the algorithms I need the intrinsic and extrinsic parameters. Do you know, where can I find the calibration file? Obviously, I can recalibrate the camera by myself, but I would like to avoid it if the calibration file is accessible.</P><P>&nbsp;</P><P>Thank You!</P><P>Renata</P> Tue, 30 Apr 2019 18:36:35 GMT https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674368#M15661 RNagy 2019-04-30T18:36:35Z https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674369#M15662 <P>A sample wheel odometry calibration file was added to the T265's documentation a week ago when SDK version 2.21.0 was released.</P><P>&nbsp;</P><P><A href="https://github.com/IntelRealSense/librealsense/blob/master/doc/t265.md#wheel-odometry-calibration-file-format">https://github.com/IntelRealSense/librealsense/blob/master/doc/t265.md#wheel-odometry-calibration-file-format</A></P> Tue, 30 Apr 2019 18:48:53 GMT https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674369#M15662 MartyG 2019-04-30T18:48:53Z https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674370#M15663 <P>Thanks Marty! Unfortunately, I need the calibration file for the fisheye cameras (e.g. to undistort the fisheye images, etc.). Can you tell me is it accessible or not? It is not a rocket science to calibrate the fisheye cameras but why do it if others did it to me :) </P> Tue, 30 Apr 2019 19:02:43 GMT https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674370#M15663 RNagy 2019-04-30T19:02:43Z https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674371#M15664 <P>Intrinsics and extrinsics of the T265 were exposed from SDK version 2.20.0 onward. Below is an example using both to render a virtual object in the fisheye frame:</P><P>&nbsp;</P><P><A href="https://github.com/IntelRealSense/librealsense/tree/master/examples/ar-basic" target="_self" alt="https://github.com/IntelRealSense/librealsense/tree/master/examples/ar-basic"></A><A href="https://github.com/IntelRealSense/librealsense/tree/master/examples/ar-basic">https://github.com/IntelRealSense/librealsense/tree/master/examples/ar-basic</A></P> Tue, 30 Apr 2019 19:14:28 GMT https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674371#M15664 MartyG 2019-04-30T19:14:28Z https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674372#M15665 <P>This is what I needed, thank you so much!</P> Tue, 30 Apr 2019 21:05:48 GMT https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674372#M15665 RNagy 2019-04-30T21:05:48Z https://community.intel.com/t5/Items-with-no-label/Where-can-I-find-the-camera-calibration-file-for-Realsense-T265/m-p/674373#M15666 <P>You're totally welcome.
