Details

Auto guiding

Four tracking technology are prepared for your point detection. Normalized cross correlation, Binarization grayscale, HLS color tracking, and Checker marker. The algorithm will try to hold onto each target as much as possible to get the 2D XY coordinate from the video data.

Binarization grayscale

Binarized tracking menu has options to get an accurate result. Center of gravity, Circle fitting, Weighting(luminance gradient), and Center of rectangle. These options will help you to extract the center position of the target.

Checker marker

Checker marker tracking method is proactively used in automotive experiments. Brightness gradient and symmetry-based detection will make your analytical work easier and efficiently.

Pre processing

Transformation (flip, rotation, trimming, canvas size, resize, keystone correction, affine transformation) tools will help you correct the narrow camera position image to a vertical image.

Calibration

Lens distortion correction

DIPP-Motion has a powerful lens distortion correction tool to get rid of the distortion of each lens and camera.This tool is specially useful for wide imaging and X-ray imaging.

Pre processing

Data analysis

All kinds of XY/XT charts are available for DIPP-Motion such as point, distance from begin, average point, distance between markers, rotation angle , three points angle , two line angle(for X,Y as 2D) (for X,Y,Z,XYZ as 3D), ROLL/PITCH/YAW (for 3D rigid body model). The DATA can be output in CSV(text files) and AVI/WMV (movie files).

Correlation Coefficient Map

3D calibration and rigid body models

DIPP-Motion uses DLT method to take out 3D real coordinates by estimating each channel's camera parameter. Using more than three 3D points, the software can calculate 6 DOF instinctively.
