Prerequisites(Update config file)

  • You can find Depth 50°’s config file in D1000-50 , Depth 120°’s config file in D1000-120

  • Config file in HD folder means using for 720p, VGA for 480p. You need calibrate both resolution for camera.

  • Copy and paste eDepthK.prj to mynteye-d-calibrator_1.0 folder.

  • Open eDepthK.prj with txt and modify Col1/2/3/4 to chessboard width, Row1/2/3/4 to chessboard height, Size1/2/3/4 to chessboard square size in meters.

  • Chessboard width and height refer to the number of black and white intersections in the horizontal and vertical directions of the checkerboard.

Example of 11x7 Intersection Chess Board

Parameters of eSPCalibrator

1.Open eDepthK.prj 2.Note that ‘Col1’ ‘Row1’ ‘Size1’ must match your chess board

Calibration Procedure 1 (Yoffset)

  • If you are calibrating VGA mode,please skip this procedure.

  • Calibration Process 1 need 1 picture.

  • The chess board must right in front of both camera and cover maximum portion(over 50%) of the preview image(try your best)

  • Press ‘c’ or ‘C’ to take the snapshot of the properly positioned chess board. If calibrator can not detect all the intersections on preview image, you will get “Not Found” result.

Operation guide

1.Double click mynteye-d-calibrator.exe 2.Press ‘c’ or ‘C’ to take the snapshot (total one frame)

Calibration Procedure 2 (Calibration)

  • Calibration need 5 pictures in 5 different angles

  • The required angles will be the combination of rotation along X and

Y axis. Each Rotation angle should be 10° to 30° and/or Y-axis around X- axis

  • The chess board must cover the maximum portion(over 50%)

of the preview image from both camera(try your best)

  • Press ‘c’ or ‘C’ to take the snap shot of the properly positioned chess board. If calibrator can not detect all the intersections on the chess board, you will get “Not Found” result.

Calibration Result

  • After calibration, parameters will auto write into device.

  • After caliobration, you can get Reprojection error in log file StereoSetting.txt , it is desirable to have a reprojection error of 0.2 or less. If exceeds 0.5, it needs to be recalibrated.

Log File

  • After caliobration, log file will save into Log_Folder .
