Reality augmenting method and system based on wearable device

The invention provides a reality augmenting method and system based on a wearable device. The reality augmenting method based on the wearable device comprises the steps that images, at multiple angles, of an object to be virtualized are obtained through shooting by means of the wearable device; a three-dimensional virtual model of the object to be virtualized is established according to the images, at the multiple angles, of the object to be virtualized, wherein the three-dimensional virtual model has the initial overall dimension; the initial overall dimension of the three-dimensional virtual model is corrected, so that a target overall dimension of the three-dimensional virtual model is obtained; the three-dimensional virtual model with the target overall dimension is superposed into a selected real scene, so that a virtual-real fusion image is obtained. According to the reality augmenting method and system based on the wearable device, the dimension of the three-dimensional virtual model can be modified freely by a user according to the preference of the user and is better superposed into the real scene, in this way, the reality augmenting effect is improved, and cost is quite low.
