For the measurement of objects with highly reflective surfaces，the traditional fringe projection method cannot measure the complete 3D information． In order to solve this problem，this paper adopts the region mapping a- daptive fringe projection method ( ＲMAFP) ，which distinguishes the saturated region by the grey value of the image， and then adopts the improved phase-shift algorithm to get the phase and saturation of the saturated region; by the phase value to achieve the projection region mapping，and then project the standard fringe map corrected according to the saturation，and then remeasure the original saturated region，which can eliminate the saturation phenomenon，and combined with the original non-saturated region Combined with the high-precision phase of the original non-saturated area，the accurate measurement of highly reflective objects can be completed． The experiments show that this method is practical and feasible，and can complete the measurement of complex high-reflectivity surfaces．
