Figures 3 to 5 show one embodiment, in which the repellence system is arranged in connection with or to the unmanned aerial vehicle 10. Thus, figures 3 to 5 schematically show utilization of the repellence system with the unmanned aerial vehicle 10 for repelling animals.

It should be noted, that the unmanned aerial vehicle 10 may also be replaced with an unmanned ground vehicle.

As shown in figure 3, the unmanned aerial vehicle 10 patrols a predetermined geographical surveillance area 30. When the unmanned aerial vehicle 10 is an autonomous unmanned aerial vehicle 10, the unmanned aerial vehicle 10 is configured to move a pre-determined route in the surveillance area 30 or move according to control instructions stored or provided to the control unit 13. The predetermined geographical surveillance area 30 is determined by location coordinates stored in the repellence sub-system 51. Thus, geographical location information of the predetermined geographical surveillance area 30 is stored to the repellence sub-system 51.

The geographical location information of the predetermined geographical surveillance area 30 may be determined with global navigation satellite system (GNSS) coordinates, such as Global Navigation System (GPS) coordinates.

The unmanned aerial vehicle 10 generates image data from the surveillance area 30 with the imaging device 14 during the patrolling. The image data is processed with the repellence sub-system 51 continuously and in real-time for detecting and identifying animals in the surveillance area 30.

Accordingly, predetermined geographical surveillance area 30 may be any land or sea area. The predetermined geographical surveillance area 30 has the perimeter or border 32 inside which is the predetermined geographical surveillance area 30. Outside the border 32 is surrounding area 34, which is so called free area where the unmanned aerial vehicle 10 does not patrol.

The object of the repellence system of the present invention is to repel animals detected and identified inside surveillance area 30 out of the predetermined geographical surveillance area 30 to the free area 34 outside the surveillance area 30.

It should be noted that in the present invention the animals detected inside predetermined geographical surveillance area 30 are identified to identify the species of the animals. Identifying the species of the animal is important such that effective deterrence actions maybe used. The effective deterrence actions are specific to the identified animal species.

As shown in figure 3, the repellence system provided to the unmanned aerial vehicle 10 detects an animal 40 inside the surveillance area 30.

The repellence sub-system 51 comprises deterrence instructions for different animal species. Thus, after identification of the animal species of the detected animal 40 with the repellence sub-system 51, the repellence sub-system 51 is configured to generate deterrence instructions specific to the identified animal species. The repellence sub-system 51 is further configured to provide the species specific deterrence instructions to the one or more deterrence devices 16, 18 and the deterrence devices 16, 18 are configured to carry out species specific deterrence actions based on the species specific deterrence instructions.

In certain situations, the repellence sub-system 51 is unable to identify the detected animal 40 in the image data. This maybe due to great distance between the imaging device 14 and the detected animal 40 or due to for example weather conditions, such as rain or fog. In this case the repellence sub-system 51 is configured to generate control instructions for controlling the movement of the unmanned aerial vehicle 10. The repellence sub-system 51 is configured to provide the control instructions to the control unit 13 of the unmanned aerial vehicle 10 for automatically controlling the movement of the unmanned aerial vehicle 10. Alternatively, when the unmanned aerial vehicle 10 is not an autonomous unmanned aerial vehicle 10, the repellence sub-system 51 provides the control instructions to a user of the unmanned aerial vehicle 10 or to remote controller of the unmanned aerial vehicle 10.

The repellence sub-system 51 is configured to generate control instructions controlling the unmanned aerial vehicle 10 towards the detected animal 40, as shown with arrow D in figure 3, such that the distance between the animal 40 and the unmanned aerial vehicle 10 or the imaging device 14 decreases. The imaging device 14 is configured to generate image data continuously and the repellence sub-system 51 is configured to receive the image data from the imaging device 14 continuously.

The repellence sub-system 51 is configured to process the image data continuously such that each received image or image frame is processed to detect and identify the animal 40. Thus, the repellence sub-system 51 is configured to generate or update the control instructions based on each image or each frame received in repellence sub-system 51.

The control unit 13 is configured to control the unmanned aerial vehicle 10 to fly at a height of 2 to 100m from the ground.

Usually, the repellence sub-system 51 is configured to control the unmanned aerial vehicle 10 towards the detected animal 40 to a deterrence distance from animal 40. When the deterrence distance is reached, the repellence sub-system 51 is configured to initiate the species specific deterrence actions with deterrence devices 16, 18 by providing the deterrence instructions to the deterrence devices 16, 18.

The deterrence distance may also be pre-determined and further it may be specific to the animal species. Thus, the repellence sub-system 51 is configured to store a pre-determined deterrence distance threshold value, control the unmanned vehicle 10 towards the detected animal 40, determine distance between the unmanned vehicle or the unmanned aerial vehicle 10 and the detected animal 40 continuously as the unmanned aerial vehicle 10 is controlled towards the detected animal 40, and initiate the species specific deterrence actions with the one or more deterrence devices 16, 18 when the determined distance is equal to or less than the pre-determined deterrence distance threshold value.

Determining the distance between the unmanned vehicle or the unmanned aerial vehicle 10 and the detected animal 40 is carried out from the image data with the repellence sub-system 51. Therefore, the between the unmanned vehicle or the unmanned aerial vehicle 10 and the detected animal 40 is determined from images or from each image or each image frame.

Alternatively, the unmanned aerial vehicle 10 is provided with a distance measurement device (not shown), such as a laser measurement device, generating distance measurement data and being connected to or operatively connected to the repellence sub-system 51.

Alternatively, the periphery location 3 is the location of the periphery 32 closest to the detected animal 40.

The animal 40 may be moving in an animal moving direction A and possibly also the moving velocity, as shown in figure 4. The repellence sub-system 51 is configured to determine the animal moving direction A from the image data of the imaging device 14.

The repellence sub-system 51 is configured to determine animal moving direction A and possibly also the moving velocity based on the successive images or image frames in the image data. Thus, the animal moving direction and possibly also moving velocity is updated continuously.
