Title:
GEOPHONE LOCATING ACCURACY EVALUATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/105173
Kind Code:
A1
Abstract:
A geophone locating accuracy evaluation method, provided with a geophone, wherein the geophone is correspondingly provided with at least one shot point and has locating position data; the geophone has a characteristic parameter corresponding to each shot point; and the characteristic parameter comprises a shot-geophone distance, a first arrival wave speed and a first arrival time. The method comprises: step S10, constructing a residual vector between the geophone and each shot point on the basis of the characteristic parameter; step S12, determining a characterization parameter for locating position data on the basis of the residual vector; and step S14, evaluating the accuracy of locating position data by using the characterization parameter. Further provided is a geophone locating accuracy evaluation device.
