Abstract: A vision-haptics fused augmented reality simulator for dental surgical skill training, including a dental simulation training platform constructed based on an artificial head phantom; a dental operation training system based on a haptic feedback device; an observation system based on an augmented reality head-mounted display; generating a virtual dental model by modeling based on CBCT data and scan data of a patient's dental cavity, to construct a virtual dental environment; based on the virtual dental model and feature points obtained through scanning on the artificial head phantom, performing a spatial matching of a virtual dental cavity and a dental model; in a virtual dental surgery simulation method, outputting haptics information and visual information at frequencies of not less than 1000 Hz and 60 Hz, respectively; performing a visual information processing method on grid data; and performing a haptics-vision space calibration method based on information of an operator's head.
