The invention provides a human body characteristic visualization device. The human body characteristic visualization device is capable of visualizing non-dominant human body characteristics in the various parts of a human body and even in the whole body, so that the intuitive location of an observer is achieved and the position and morphology information of the non-dominant characteristics of the human body are mastered; specifically, the human body characteristic visualization device comprises a three-dimensional scanning device which, together with a visualization device, defines a visual space, and a data processing device which is stored with human body characteristic information and is used for processing the three-dimensional information in a human body detected part acquired by the three-dimensional scanning device, so that the visualization device is controlled within the visual space, and the matched visual human body characteristic information is released from the body surface region of the human body detected part.
