Abstract: The present disclosure provides a method and system for determining an optimal flight height of an unmanned aerial vehicle (UAV), an electronic device, and a medium. The method includes: obtaining a multi-band crop spectral image of an experimental area in a preset scenario; performing data processing on the multi-band crop spectral image, to obtain multi-spectral orthographies of a plurality of sample plots; calculating a ground resolution of the multi-spectral orthography of each sample plot, simulating and determining a multi-band crop spectral image of each sample plot at a different flight height by a nearest neighbor interpolation method based on the ground resolution of the multi-spectral orthography of each sample plot; and for the multi-band crop spectral image of each sample plot at the different flight height, determining an optimal flight height corresponding to each sample plot by a hypothetical test method.

Abstract: The present disclosure relates to the field of artificial honeycombs, in particular to an artificial nest for solitary bees and an application method of the artificial nest. The artificial nest comprises a main enclosure tube, hanging rings, a plurality of trapping hollow tubes and tightening mechanisms used for clamping the trapping hollow tubes. The hanging rings are arranged at an outer sidewall of the main enclosure tube. The tightening mechanisms are annularly arranged at an inner sidewall of the main enclosure tube, and the trapping hollow tubes are fixed in a ring of each tightening mechanism in an axis direction of the main enclosure tube. Each tightening mechanism comprises a connecting steel wire and fastening springs. The sidewall of the main enclosure tube is provided with fixing holes for fixing the tightening mechanisms.
