Patent Images

1. the parcel volume measurement device of view-based access control model, it is characterized in that, comprise:

  • be arranged on the camera directly over the parcel light curtain module of travelling belt both sides and light backstage side travelling belt, described light curtain module and camera are connected to message processing module, described message processing module also connects image analyzing unit, parameter input module and data outputting module, and the video output terminals of camera connects image analyzing unit;

    Described light curtain module produces light curtain on travelling belt cross section, and when wrapping up through light curtain, light curtain module measures the height h of parcel, then elevation information is transferred to message processing module;

    After message processing module receives the data of light curtain module, send photographing signals at once to camera, camera carries out the collection of wrapping up image information, then collected image information is transferred to image analyzing unit;

    After image analyzing unit carries out analyzing and processing to the image information gathered, the pixel wide M of samples pictures and parcel area pixel area S is transferred to message processing module;

    By parameter input module, the camera distortion factor alpha prior experimental analysis calculated, camera Width visual angle β and

    camera are transferred to message processing module to the vertical range H of travelling belt;

    Message processing module carries out comprehensive analytical calculation to the data received, and obtains the volume V wrapped up, then inclusion volume data is exported by data outputting module.
