摘要
A method for rapidly creating an indoor wireless signal fingerprint database, comprising the following steps: constructing an indoor and outdoor combined three-dimensional scene model of a target building, predicting wireless signal field intensity information of 3D space using a ray-tracing algorithm, selecting a small quantity of testing points to perform manual field measurements and recording the wireless signal intensity information, correcting/calibrating 3D ray-tracing propagation model parameters based on the difference between the actually measured wireless signal intensity information and the theoretical wireless signal intensity information calculated through the 3D ray-tracing propagation model.
