characteristic:

The device blocks external light and captures foot movements in dark conditions; Continuous walking on the B-type walkway is achieved by recording the natural walking part in reverse, detecting the movement image of the sole, as well as the step length and walking cycle.

Software performance:

Image processing: lens distortion calibration, mask noise reduction, adjustment of image contrast and brightness, reduction of analysis area

Foot detection: designation of landing point and landing foot (manual), landing detection and release time (automatic), and foot direction (manual)

Screen display: Composite video image playback (single/full display footprint map), area map, stance phase bar, time and distance factors, and foot/ground/foot direction table.

Result output: CSV output (stride length, walking cycle, contact/release time, angle, sole area), still image output, video output

Other: Simple numerical calculations (distance and angle between any point on the moving image screen)

Data management: Centralize the management of videos and analysis results in the database. Add keywords such as personal ID, measurement date, experimenter, and search information.
