The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The implementation of the present embodiment is described in detail below with reference to the specific drawings.
Embodiment one:
as shown in fig. 1 to 5, a vibration-damping type pan-tilt is provided in this embodiment, which includes a handle 2, a plurality of motors 11, and a connection arm 12 connected between adjacent motors 11, the plurality of motors 11 in this embodiment include a heading axis motor 11, a roll axis motor 11, and a pitch axis motor 11, wherein the heading axis motor 11 is mounted at the end of the handle 2, the connection arm 12 is mounted between the output end of the heading axis motor 11 and the body of the roll axis motor 11, the connection arm 12 is mounted between the output end of the roll axis motor 11 and the body of the pitch axis motor 11, and the output end of the pitch axis motor 11 is used for mounting a photographing apparatus 4 such as a mobile phone, a moving camera, and the like. Since there is only a difference in the positions of the heading axis motor 11, the roll axis motor 11 and the pitch axis motor 11 in the specific implementation of the present embodiment, it is not necessary to make a distinction description, and for the sake of simplicity and brevity of description, they will be collectively referred to as a motor 11 hereinafter unless otherwise noted.
Any connecting arm 12 of the vibration-damping cradle head comprises a front arm 121 and a rear arm 122 which are independent from each other, and the front arm 121 and the rear arm 122 are connected through a vibration-damping structure 13 capable of floating and absorbing vibration. In other words, the connecting arm 12 is cut off from the middle, and the vibration canceling structure 13 is mounted at the cut off so that vibration cannot be transmitted between the front arm 121 and the rear wall.
Specifically, the vibration absorbing structure 13 may be disposed on a connecting arm 12 (generally referred to as a vertical arm) between the heading axis motor 11 and the roll axis motor 11, may be disposed on a connecting arm 12 (generally referred to as a cross arm) between the roll axis motor 11 and the pitch axis motor 11, or may be disposed on both connecting arms 12.
Because the handheld cradle head is used, a user holds the handheld cradle head to carry out mobile shooting, and vibration born by the whole vibration-damping cradle head comes from the hand of the user. The vibrations are first transferred to the handle 2, which is in direct contact with the user's hand, and then transferred to the photographing apparatus 4 via the heading axis motor 11-the connecting arm 12-the roll axis motor 11-the connecting arm 12-the pitch axis motor 11-the photographing apparatus 4, which ultimately affects the photographing effect.
By adopting the vibration absorption type cradle head in the embodiment, the vibration is absorbed when being transmitted to the vibration absorption structure 13 of the connecting arm 12, and cannot be continuously transmitted along the connecting arm 12, so that the transmission path of the vibration is cut off, the influence of the vibration on the shooting equipment 4 is eliminated, the dynamic stability enhancement effect is further improved, and the shooting of higher-quality videos under dynamic conditions is facilitated.
As shown in fig. 2, 3 and 4, the shock absorbing structure 13 specifically includes a mounting block 131 mounted to the front arm 121 and a slider 132 mounted to the rear arm 122. A recessed cavity 1314 is formed in the interior of the mounting block 131, a slider 1321 is provided at one end of the slider 132, the slider 1321 is disposed within the recessed cavity 1314 and is in clearance fit therewith, and a plurality of cushioning members 133 are provided between the side walls of the recessed cavity 1314 and the side walls of the slider 1321 for cushioning. When the slider 132 or the mounting block 131 is vibrated, the slider 1321 is floatingly displaced in the recess 1314, and the corresponding cushion member 133 cushions the slider 1321, absorbs the vibration, and thus intercepts the transmission path of the vibration. The buffer member 133 may be implemented by a flexible structure such as a spring, a gas spring, a latex pad, etc., which is elastically deformed and absorbs vibration after being compressed. In other embodiments, the shock absorbing structure 13 may be implemented by other structures, for example, including two mounting plates mounted to the front arm 121 and the rear wall, respectively, with a spring disposed longitudinally therebetween, and the like.
As shown in FIG. 3, the recess 1314 in this embodiment is rectangular in cross-section, and the floating head 1321 has two parallel longitudinal side walls 1324, the distance between the longitudinal side walls 1324 being equal to the width of the recess 1314. That is, after the floating head 1321 is placed in the concave 1314, the two longitudinal side walls 1324 thereof are respectively contacted with the two side walls of the concave 1314, so that the floating head 1321 can only float along one direction, the vibration is eliminated by orientation, and the problems of non-orientation, oversized travel and the like of the floating head 1321 are avoided.
Preferably, the upper end and the lower end of the floating head 1321 are convexly provided with a limiting block 1322, two raised lines 1312 are arranged in the concave cavity 1314 corresponding to the side wall, a limiting groove 1313 in which the limiting block 1322 can be placed is formed between the two raised lines 1312, a certain gap is reserved between the limiting block 1322 and the bottom of the limiting groove 1313 after the limiting block 1322 is placed, a buffer piece 133 is arranged in the gap, the floating direction of the floating head 1321 is further limited, and the floating head 1321 is prevented from falling from the concave cavity 1314 on the premise of ensuring floating. In other embodiments, the limiting block 1322 may be disposed only at one selected end of the upper end or the lower end of the floating head, which also plays a role in limiting and damping.
Since the connecting arm 12 is not only structurally connected to the motor 11, but also requires internal wiring, the slider 132 is provided with a first preformed hole 1323 and the mounting block 131 is provided with a second preformed hole 1311 connected to the cavity 1314, and the connecting wires can pass through the first preformed hole 1323, the cavity 1314, and the second preformed hole 1311 in sequence, thereby passing through the entire shock absorbing structure 13.
The vibration absorbing structure 13 and the connecting arm 12 may be mounted in various manners, for example, the vibration absorbing structure 13 may be directly mounted by bolts, specifically, in this embodiment, as shown in fig. 2, the connecting portions of the front arm 121 and the rear arm 122 are respectively provided with a mounting cavity 123, the mounting block 131 and the floating block 132 can be placed in the corresponding mounting cavities 123 and fixedly mounted, only the seam is left on the surface of the connecting arm 12 after the mounting is completed, and the vibration absorbing structure 13 cannot be observed, so that the appearance consistency is good, and in addition, foreign matters such as dust can be prevented from entering the vibration absorbing structure 13 to affect the floating stroke thereof.
Preferably, as shown in fig. 1, the vibration-damping holder further comprises a floating sleeve 21 sleeved outside the handle 2, the floating sleeve 21 and the handle 2 form clearance fit, and a plurality of buffer members (not shown) are arranged between the floating sleeve 21 and the handle 2. The floating cover 21 replaces the handle 2 as a part directly held by the user, and after the floating cover receives vibration from the hand of the user, the vibration transmitted to the handle 2 by the hand is reduced by directly buffering the vibration between the floating cover and the handle 2 through a buffer piece.
Preferably, as shown in fig. 5, the handle 2 includes an operation part 22 and a hand-holding part 23, wherein the upper end of the operation part 22 is provided with a heading shaft motor 11, the lower end of the operation part 22 is provided with a connecting shaft 221, the hand-holding part 23 is provided with a connecting hole 231 for inserting the connecting shaft 221 and forming a clearance fit, and a buffer member 133 is arranged between the connecting hole 231 and the connecting shaft 221. When the hand-held portion 23 receives vibration, the buffer member 133 between the connection hole 231 and the connection shaft 221 buffers and absorbs the vibration, reducing the vibration transmitted from the hand-held portion 23 to the operation portion 22, and in turn reducing the vibration received by the heading shaft motor 11.
The embodiment also provides a video offset processing method: the method comprises the following steps:
recording the floating travel of the vibration damping device and the floating time t during shooting;
and (3) corresponding the time t to the segment alpha of the shot video in the time t, processing the segment alpha according to the time relation corresponding to the floating travel, and correcting the generated picture offset.
According to the video offset processing method, the floating travel and the occurrence time of the floating device are used as data references, and the shot video is automatically analyzed and processed in the later stage, so that the influence of vibration on the video is further reduced.
Embodiment two:
as shown in fig. 6, another vibration-damping cradle head is provided in the present embodiment, which also includes a plurality of motors 11a and connecting arms 12a connected between adjacent motors 11a, and is different from the first embodiment in that a vibration-damping structure 13a is provided at the connection between any connecting arm 12a and the corresponding motor 11a in the present embodiment.
The vibration absorbing structure 13a is capable of floating to absorb vibrations, and prevents the vibrations from being transmitted from the connection arm 12a to the corresponding motor 11a, thereby cutting off the transmission path of the vibrations.
Other structures and technical effects in this embodiment are the same as those in the first embodiment, and will not be described again.
