The embodiment of the invention provides a field intensity prediction method and device and computer equipment. The method comprises the following steps: acquiring coordinate information of a target measurement point in a target area, inputting the coordinate information into a corrected ray tracking field intensity prediction model, and obtaining the receiving field intensity of the target measurement point output by the ray tracking field intensity prediction model. Thus, in the model correction process, the influence of propagation parameters and scene parameters is considered, so that thereceiving field intensity of the target measurement point output by the ray tracking field intensity prediction model based on multipath information correction can be accurately obtained, the physicalsignificance is clearer, the application deployment range is more appropriate, and the robustness is higher.
