Non-contact Human Body Measuring Technology Based On Camera Self-calibration Technique

Three-dimensional automatic measuring for human-body is indispensable fordigitalization of clothing industry. There is substantial body of literature in this field.Measurement method based on body-topology is an effective one. This work is its furtherstudy and improvement. Contents of the thesis are as follows:(1)Pre-processing of the camera image: the most advantageous algorithm with Cannyoperator for fringe detection is adopted in comparing with different methods.(2) Self-calibration camera: considering the abnormality eliminating accompanying withself-calibration, the measurement precision is improved with simplified manipulation.(3)3D reconstruction for the body measured with database: application software isimplemented by using C Sharpe.It is verified by measuring test that the software system is feasible. The effect ofmeasurement is improved, capable of using in natural environment added by tungsten light,employing a portable calibrator. The initial cost of the apparatus is reduced.
