Abstract
The application provides an estimation method of detecting elevation by a semi-airborne electromagnetic method, including the following steps: S1, judging original elevation data to obtain wrong point data and normal data; S2, filtering the wrong point data by an improved Kalman filtering method, and filtering the normal data by a conventional Kalman filtering method; S3, fusing a filtering result of the wrong point data and a filtering result of the normal data, and taking a fused result as a measured value sequence used in a next working process; and S4, repeating the S1-S3 until the fused result meets preset requirements.
