1. a gait recognition method, comprises stereoscopic vision and demarcates, trains and identify,Described stereoscopic vision is demarcated, for demarcating stereoscopic vision twin camera;

  • Described training, for training obtained three-dimensional gait data storehouse, this training comprises the following steps;

    Obtain training gait image sequence pair;

    Extract moving target profile;

    Stereo matching obtains three dimensional point;

    Extract three-dimensional gait feature;

    Use principal component method to carry out dimensionality reduction to described three-dimensional gait feature, obtain the three-dimensional gait data storehouse trained;

    Described identification, for classifying to three-dimensional gait feature;

    Described stereoscopic vision is demarcated and is comprised the following steps;

    the standard cross-hatch pattern picture collected by stereoscopic vision twin camera is transferred to computing machine;

    Pre-service is carried out to described standard cross-hatch pattern picture;

    Extract the unique point required for demarcating;

    Described stereoscopic vision twin camera inside and outside parameter is separately demarcated;

    Demarcate the relative space position parameter between described stereoscopic vision twin camera;

    Preserve the calibration result value after calibration.
