Abstract: In some embodiments, a method receives a video including interlaced frames. Second fields for a second frame and the second fields for a third frame are analyzed to determine estimated second fields for the first frame in an image space. The method converts the first fields and the estimated second fields for the first frame into first features and second features, respectively, in a feature space. The estimated second features are determined for the estimated second fields for the first frame based on the first features for the first frame. Backward features from the second frame and forward features from the third frame are used to determine the estimated second features for the first frame. The method outputs a prediction for the estimated second fields for the first frame based on the estimated second features and generates a first frame with the first fields and estimated second fields.

Abstract: The present disclosure provides a flight anti-collision method and apparatus based on electromagnetic field detection of an overhead transmission line. An example method includes: determining whether an overhead transmission line around is an Alternating Current (AC) transmission line or a (Direct Current) DC transmission line; if the overhead transmission line is an AC transmission line, determining a position relationship between an aircraft and the overhead transmission line on the basis of a phase distribution model and an electric field phase and a magnetic field phase measured by a phase detector on the aircraft; if the overhead transmission line around is a DC transmission line, determining the position relationship between the aircraft and the overhead transmission line on the basis of a magnetic field intensity distribution model and the magnetic field intensities collected by magnetic field intensity sensors on the aircraft; and thus controlling the aircraft.
