Title:
FARMLAND DATA FUSION PROCESSING METHOD EMPLOYING MULTIPLE SENSORS
Document Type and Number:
WIPO Patent Application WO/2020/140189
Kind Code:
A1
Abstract:
A farmland data fusion processing method employing multiple sensors comprises: determining a first average value according to a greatest actual measured value and a smallest actual measured value (S3); performing comparison and classification on multiple actual measured values according to the first average value, and acquiring a positive set and a negative set (S4); determining a second average value on the basis of actual measured values in the positive set, and determining a third average value on the basis of actual measured values in the negative set (S5); determining a fourth average value according to the second average value and the third average value (S6); performing determination and comparison according to the first average value and the fourth average value, and outputting the first average value (S7); and determining, on the basis of the first average value, a data fusion value corresponding to sensors of the given type (S8), thereby fusing data acquired by multiple sensors. The invention further improves the accuracy of a data fusion result.
