The invention provides a self-defined visual angle image generation method based on a single real shot image and pose information. The method comprises the following steps: shooting an original image at the current moment by using a camera installed on an aircraft; obtaining the pose information of the aircraft at the current moment by using an inertial navigation system; obtaining the vertical distance from the center of the camera to the ground at the current moment based on the height of the aircraft at the current moment and the altitude of the aircraft on the ground; acquiring a rotation matrix from a carrier coordinate system to a navigation coordinate system at the current moment based on a roll angle, a pitch angle and a yaw angle of the aircraft at the current moment; converting the ground normal vector twice to obtain a unit normal vector of the imaging plane in a camera coordinate system; obtaining a homography matrix between the target view angle image and the original image; and performing homography transformation on the original image based on the homography matrix between the target view angle image and the original image, and generating an analog image under the user-defined view angle.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain.

The subject of the application is a device for dropping vaccine for wild animals from an aircraft, comprising an aircraft (1) with a control module (2), a navigation system (3) and a wild animal detection system (4), and the device is equipped with a vaccine reservoir (5) with an outlet opening in its bottom, under which a vaccine feeder (6) is located. It is characterized in that the vaccine reservoir (5) is equipped with a revolver mechanism adapted to sequentially position the vaccine portion storage chambers above the outlet opening, the revolver mechanism being connected in its axis to the shaft of a drive motor (7) connected to a control module (2). The vaccine feeder (6) is a dosing-paddle feeder consisting of blades (8) attached transversely to a motor shaft (9), preferably a stepper motor, connected to the control module (2).An aircraft (1) is equipped with a winch (10) with a cable at the end of which an odor sensor (11) is connected to a control module (2). A method of dropping a vaccine for wild animals from an aircraft involves designating a flight route for the aircraft (1) to ensure precise distribution of the vaccine throughout the vaccination area, and the aircraft (1) then flies along this route. The method involves lowering an odor sensor (11) from the aircraft (1) to the ground surface during the flight at locations stored in the navigation system (3) using a winch (10) to collect odor data.If an odor corresponding to a pre-defined odor pattern of wild animals being the target for vaccination is detected, the control module (2) activates the vaccine feeder (6) and, after emptying the currently set vaccine portion storage chamber in the vaccine reservoir (5), activates the revolver mechanism for sequential positioning of subsequent vaccine portion storage chambers above the outlet opening.
