A method for driving fan blades of a clean-energy generator comprises: setting a magnetic suspension rotation device. A hub (1) is arranged in the magnetic suspension rotation device. Multiple fan blades (3) arranged in a radial direction are embedded on a fender trim (2). Top ends of the fan blades (3) are mounted with bearings, and are embedded on a ring-shaped magnetic suspension running track (4). The hub (1) is provided with a long through rotation axis (5), and is embedded with multiple groups of magnetic suspension devices. Gears (9) having an inertia effect are embedded on the axis to drive a storage generator (10) on a tower platform, so as to charge a storage battery (14) and supply power through a rectification voltage stabilizer to start a motor and a magnetic suspension device. Also disclosed is a device for driving fan blades of a clean-energy generator. The device comprises: a bearing support being fixed on a platform (7), an auxiliary motor (18) being connected with a fan-shaped ...

Image retrieval method and device, machine readable medium and equipment

Номер: CN116561366A

Принадлежит:

The invention discloses an image retrieval method. The method comprises the following steps: acquiring a target feature vector of a to-be-retrieved image; matching the target feature vector with a feature library constructed based on a reverse index mode to obtain a base library feature vector matched with the target feature vector; wherein the base library feature vector is obtained by mapping an original feature vector from a first feature space to a second feature space, so that the base library feature vector is redistributed in the second feature space; and outputting an image to which the bottom library feature vector belongs to obtain a target image. Based on the feature data redistribution technology, the base library feature data are remapped into a uniformly distributed feature space, and more uniform feature distribution is beneficial to a subsequent retrieval algorithm based on an inverted index (IVF), so that the data volume of a plurality of small base libraries divided by ...
