The invention relates to an ultrasonic bird repelling method and device, a bird repelling device and a storage medium. The method comprises the steps that according to a preset first bird repelling time period, a preset second bird repelling time period and a preset third bird repelling time period, a target bird repelling time period where the current moment is located is determined; according tothe target bird repelling time period, the historical temperature of a previous day and a preset mapping relation set, a bird repelling device starting interval duration T1 corresponding to the target bird repelling time period is determined; and then a bird repelling device is triggered to work for a duration T2 at an interval of the bird repelling device starting interval duration starting interval duration T1. That is to say, different bird repelling time periods are set according to the activity frequency of birds, different bird repelling device starting interval durations T1 are set according to different temperatures in the different bird repelling time periods, the bird repelling device is triggered to work for the duration T2 according to the different bird dispeller starting interval durations T1, so that the situation that a traditional ultrasonic bird dispeller is poor in bird dispelling effect due to the fact that the bird repelling device starting interval duration is fixed is avoided, and the bird dispelling efficiency of ultrasonic bird dispelling is improved.

The invention discloses a laser bird repelling method and system based on three-dimensional information estimation in the field of bird repelling technology, which can automatically search for bird activity traces and accurately identify bird targets, and carry out targeted bird repelling without manual participation, improving the Bird repellent efficiency. Set up the pan / tilt on the movable platform, set up binocular cameras and lasers on the pan / tilt, including: collect the left-eye image and right-eye image in the set environment; detect whether there is a bird target in the left-eye image based on Fast R-CNN, and obtain the left-eye The position information of the bird target in the image; confirm the position information of the bird target in the right eye image according to the position information of the bird target determined in the left eye image; according to the position information of the bird target in the left eye image and the position information in the right eye image The position information in the bird target determines the parallax value of the bird target, and obtains the three-dimensional position information of the bird target according to the parallax value of the bird target; adjusts the orientation of the laser according to the three-dimensional position information of the bird target and emits the laser to drive the bird .

The application relates to an ultrasonic bird repelling method, device, bird repelling device and storage medium. The method includes: determining the target bird-repelling time period at the current moment according to the preset first bird-repelling time period, the second bird-repelling time period and the third bird-repelling time period; The historical temperature of the day and the preset mapping relationship set determine the start interval T of the bird repellent corresponding to the target bird repellent time period 1 ; Then every time the bird repellent is activated, the interval is T 1 Trigger bird repellent to work T 2 duration. That is to say, the application sets different bird repelling time periods according to the frequency of bird activities, and in different bird repelling time periods, sets different bird repellent activation intervals T according to different temperatures. 1 ;Start interval time T through different bird repellers 1 Trigger bird repellent to work T 2 It avoids the poor bird repelling effect of traditional ultrasonic bird repellent due to the fixed start-up interval of the bird repellent, and improves the bird repellent efficiency of ultrasonic bird repellent.

The invention provides a wide-range bird repelling device which comprises an installation base, a fixing cylinder, a rotating shaft, at least one wind scoop and first reflectors. The installation base is suitable for being fixedly assembled with a power transmission pole in a matched mode. The fixing cylinder is fixedly arranged on the installation base and provided with an inner cavity with an upward opening. The rotating shaft is provided with a first section and a second section, wherein the first section is inserted in the inner cavity and rotationally connected with the fixing cylinder, and the second section stretches out of the inner cavity. The wind scoops are fixedly installed on the second section of the rotating shaft and can drive the rotating shaft to rotate under the action of wind force. The first reflectors are installed on the wind scoops and provided with spherical reflecting surfaces, and the spherical reflecting surfaces can reflect light rays irradiated on the spherical reflecting surfaces to repel birds. The reflection range of the first reflectors of the bird repelling device is wide, and the first reflectors can reflect light rays into the eyes of the birds once the birds appear nearby, so that the birds are startled and fly away quickly without staying or nesting on the power transmission pole, and thus the accidents such as short circuits and tripping of a line can be avoided.
