Description

{Virtual reality shooting camera gimbal with drones}

More particularly, the present invention relates to a camera gimbal for a virtual reality camera using a drone, and more particularly, to a virtual reality (hereinafter abbreviated as "VR") using a drone, It is possible to secure the desired image of the subject as much as possible by fixing the camera manufactured for shooting the image far away from the dron airframe and to correct the vertical and horizontal of the camera by its own weight and to transmit the vibration of the camera to the camera The present invention relates to a camera gimbal for VR photography using a dron.

In general, Virtual Reality (VR) is a user interface technology that uses special glasses and gloves to simulate what is possible in a software program of a computer through a sense of human being, , Literally means a world that is not real.

On the other hand, since VR photography captures all directions over 360 degrees in front, back, left, right, top, and bottom, it is difficult to shoot using general gripping device for shooting. There is no more effective and efficient way to do the drones below.

However, the drone is a vertical-directional rotor flying with a lift, and the tilting of the gas is essential for movement, and the tilting automatically occurs due to the external environment such as the wind for hovering.

However, since all the photographs including VR must be sensitive to the result, the gimbal using a three-axis gyro sensor is mainly used in the case of a general 2D photographing.

These three-axis gimbals are good for camera stability, but when the VR camera is used for 360-degree shooting, the gimbal covers almost all sides, making it impossible to obtain desired image results.

On the other hand, the conventional gimbal camera for VR photography has a general round bar shape and is configured to separate distances or to control the vertical and horizontal by controlling the servo motor.

However, when the gimbals having a general round bar shape are used and fixed to the drone at distances only from the camera, the case where the gas is caught by the VR image according to the separation distance is reduced, but in order to control the posture of the gas The camera tilts as much as it tilts, which affects the video output as well as the vibration of the gas as it is transmitted. As a result, the opposite force is generated by the gravity according to the tilting, thereby giving a fatal hindrance to the attitude control of the gas.

Also, in the case of a camera gimbals capable of correcting the inclination of a gas by connecting a servo to a round rod, an accident is often caused by the influence of the attitude control of the gas as in the case of the general round bar described above, And tilt correction of the servo are simultaneously performed, it is difficult to reduce the vertical and horizontal within a desired error.

According to the present invention,

An upper fixing plate 1 having an inverted "V " -shaped side surface 11 at its upper surface and an upper fixture 12 detachably coupled to a gimbal fixture 101 at the bottom of a drone 100;

A ring-shaped lower plate 2 fixedly installed at a position spaced apart from a bottom of the upper fixing plate 1;

The upper fixing plate 1 and the ring-shaped lower plate 2 are fixedly installed in a vertically erected shape at an angle of 120 degrees between the upper fixing plate 1 and the ring-shaped lower plate 2, Three spacing retaining rods 3 for retaining and integrally joining together;

(2) through three spring dampers (5) in a state of being disposed at a position spaced apart from a bottom surface of the upper fixing plate (1) by a bolt coupling hole (41) A floating plate 4 having a resiliently coupled shape and adapted to freely flow vertically and horizontally in response to a change in the load position of the camera transmitted through the round bar 6 according to the change of the flight direction of the drones 100;

The upper and lower end portions are rotatably pivoted on the inner side of the ring-shaped lower plate 2 and the outer side of the floating plate 4, respectively, with the angle difference of 120 degrees and being positioned between the gap holding rods 3, The length of the floating plate 4 is changed corresponding to the movement of the load of the camera 200 transmitted through the moving plate 6 and the floating plate 4 so that the floating plate 4 is allowed to flow and the vibration transmitted from the outside and the drones is absorbed Three spring dampers 5;

The upper bolt 61 is detachably coupled to the bolt coupling hole 41 of the floating plate 4 and the camera 200 is detachably coupled to the lower camera coupling bolt 62, Shaped bottom plate 2 and is transmitted to the spring dampers 5 through the floating plate 4 in response to the change of the load position of the camera 200 due to the change of the flying direction of the floating plate 4 4 are provided with a round bar 6 for buffering the spring dampers 5 and allowing them to freely flow in the vertical and horizontal directions in response to the change of the load position of the camera 200.

At this time, the upper and lower hinge parts 51 and 52 of the spring damper 5 are respectively inserted into the inner surface of the ring-shaped lower plate 2 and the outer surface of the floating plate 4 with an angle difference of 120 degrees, And three hinge insertion grooves 22 and 42 for pivotally pivoting the pins 53 and 54, respectively.

When the gimbal is coupled to the bottom of the body of the dron 100, the round bar 6 has a length that allows the position of the bottom end where the camera 200 is coupled to be positioned at least lower than the leg 102 of the dron 100, .

In addition, the round bar 6 is formed in a multi-stage so as to be adjustable in length, and round bar fixtures 63 for fixing the length-adjusted ends integrally with each other are provided at connection portions of the ends.

The camera coupling bolt 62 provided at the lower end of the round bar 6 is characterized by including 1/4 "or 3/8" bolts.

The operation effect of the dumbbell for virtual reality photography using the dron according to the present invention is as follows.

First, as shown in FIGS. 1 to 5, the camera gimbals for virtual reality photography using the drone to which the present invention is applied include an upper fixing plate 1, a ring-shaped lower plate 2, three spacing rods 3, The VR camera 200 is attached to the gimbal by a method in which the plate 4, the three spring dampers 5 and the round bar 6 are mutually coupled and detachably fixed to the bottom of the body of the drones 100. [ It is possible to minimize the problem of the dragon 100 itself being caught in the image by making it possible to separate the dragon 100 from the center so that large vibrations transmitted from the dron base can be attenuated through the spring dampers 5, And the movement for flight control of the vehicle is also attenuated.

The upper fixing plate 1 is formed using a metal plate including aluminum or the like. The upper fixing plate 1 is provided with a reverse "V" -shaped side surface 11 at the center of its upper surface, And an upper fixture 12 that is detachably coupled to the installed gimbal fixture 101, so that it is possible to easily attach and detach the camera in parallel with a general 2D imaging.

In this case, when the upper fixing plate 1 is simply formed into a triangular shape, a square shape or a circular plate shape by using a metal plate including aluminum or the like, the weight may be excessively increased. In order to reduce the area and reduce the weight, it is molded in a shape having approximately three wings, that is, a "Y" shape in plan view.

Since the existing gimbals can be fixed to the fixed V-shaped groove, it is possible to attach and detach easily when it is performed in parallel with the general 2D shooting,

Like the upper fixing plate 1, the ring-type lower plate 2 is formed to have a substantially ring shape by using a metal plate including aluminum or the like. And is formed integrally with the upper fixing plate 1 so as to be disassembled and assembled through spacing holding rods 3, which will be described later, while being disposed at distanced positions.

When the ring-shaped lower plate 2 is formed into a ring shape having the same width, the total weight may be relatively large. Therefore, in the present invention, the area is reduced as much as possible in consideration of the bending strength and the like, A plurality of arc-shaped or "V" -type grooves omitted in the reference numerals are formed on the inner and outer peripheral surfaces.

The three spacing rods 3 are formed into a circular or pipe shape having a predetermined diameter by using metal or synthetic resin containing aluminum or the like and cut to a desired length. Are vertically erected at an angle of 120 degrees between the outer bottom surface of the upper fixing plate 1 and the upper surface of the ring-shaped lower plate 2, and the upper and lower ends of the upper and lower fixing plates 1, And the ring-type lower plate 2 so that the upper fixing plate 1 and the ring-shaped lower plate 2 are maintained at a constant interval and are integrally joined.

Also, the floating plate 4 is formed to have a substantially triangular shape by using a metal plate including aluminum or the like. In order to minimize weight, a concave groove is formed on three surfaces, 41 are formed.

The floating plate 4 is disposed at a position spaced apart from the bottom surface of the upper fixing plate 1 by a predetermined distance and then through the three spring dampers 5 having a predetermined length, And is inclined freely in the vertical and horizontal directions in response to the change of the load position of the camera which is transmitted through the round bar 6 to be described later according to the change of the flying direction of the drone 100, So that it can freely flow in the vertical and horizontal directions.

The separation distance between the bottom surface of the upper fixing plate 1 and the upper surface of the floating plate 4 is set such that the round bar 6 flowing in correspondence with the change of the load position of the camera 200 is positioned within the ring- It is desirable that the three vertexes of the floating plate 4 are set so as not to hit the bottom surface of the upper fixing plate 1 when the liquid flows in the forward direction as much as possible.

The three spring dampers 5 are also called "shock absorbers ", respectively. The three spring dampers 5 are disposed at the upper and lower ends in a state of being elastically positioned between the spacing rods 3, And the hinge portions 51 and 52 are rotatably supported on the inner side of the ring-shaped lower plate 2 and the outer side of the floating plate 4, respectively.

The length of the spring damper 5 varies depending on the load movement of the camera 200 transmitted through the round bar 6 and the floating plate 4 in accordance with the change of the flying direction of the drones 100, The plate 4 is freely tilted in all directions and at the same time the vibration generated in the outside and the drone or the like is absorbed and attenuated through the rod 6 and the floating plate 4, And also performs a function of attenuating the motion for.

At this time, since the inner surface of the ring-shaped lower plate 2 and the outer surface of the floating plate 4 have the three hinge insertion grooves 22 and 42 formed at an angle difference of 120 degrees, The upper and lower hinge parts 51 and 52 of the spring damper 5 are moved in a direction in which the upper and lower hinge parts 51 and 52 of the spring damper 5 are to be pivoted between the inside of the ring type lower plate 2 and the outside part of the floating plate 4 Are inserted into the hinge insertion grooves 22 and 42 formed on the inner surface of the ring-shaped lower plate 2 and the outer surface of the floating plate 4, respectively, and then, using the hinge pins 53 and 54 So that it can be pivoted.

When the gimbals of the present invention are connected to the bottom of the body of the drones 100, the bottom end of the round bar 6, to which the camera 200 is coupled, is positioned at least lower than the legs 102 of the drones 100 And an upper end bolt 61 detachably coupled to the bolt coupling hole 41 of the floating plate 4 is provided at an upper end of the upper bolt 61, And a camera coupling bolt 62 is provided.

At this time, the camera coupling bolt 62 provided at the lower end of the round bar 6 is provided with a replaceable 1/4 "or 3/8" bolt, Rigging is also possible.

The round bar 6 is detachably coupled to the bolt coupling hole 41 of the floating plate 4 and the camera coupling bolt 62 at the lower end of the round bar 6 includes a VR- The camera 200 is detachably coupled.

The round bar 6 coupled between the floating plate 4 and the camera 200 is moved in accordance with the tilt change of the camera 200 that changes in real time due to the change of the flying direction of the drones, (I.e., flows vertically and horizontally corresponding to the weight of the camera) in the ring-shaped lower plate 2 as shown in FIGS. 4 (a) and 4 (b) To the spring dampers 5 to float the spring damper 5 so that the floating plate 4 freely flows in the vertical and horizontal directions in response to the change of the load position of the camera 200, 200 maintain the same position at all times.

The round bar 6 is not limited to being manufactured to have a predetermined length as described above. The round bar 6 may be formed in a multi-stage so as to be adjustable in length as shown in FIG. 6, The length of the round bar 6 can be freely adjusted (that is, extended and reduced) in the same way as the conventional bar camera fixture is provided with the round bar fasteners 63 for fixing the legs to each other, It is possible to separate the VR camera from the gimbals fixing part, thereby minimizing the problem that the dron gas itself is caught in the image.

Although the preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
