Description

Novel remove photographic pulley of time delay

Technical Field

The invention relates to a pulley which is used for the photographic and video production industry and is arranged on a tripod, in particular to a pulley which can automatically advance directionally and quantitatively and control a camera to take pictures under the control of a remote controller.

Background

The delayed photography is a mode of photography, and people often see whitish clouds caused by a tsunami, people who flash at a high speed, sunrise and sunset with a 5-second lens, blossom and thanks with a 3-second lens, rapid change of cities and rapid movement of stars in a movie, and the photography method of condensing objects which originally slow in the evolution process into the lenses in a short time such as several seconds is called delayed photography.

The existing delayed photography technology generally mainly uses delayed photography with a fixed lens, and the method is that a camera is installed on a tripod head to be fixed, then the tripod is fixed, the whole process does not move any more, and after the camera views, for example: shooting one picture every 5 seconds, continuously shooting 100 pictures, playing the pictures at the speed of 25 pictures per second by using later software, thus forming a final time-delay film, and the time-delay shooting characteristic of the fixed lens is as follows: scenes in the picture, such as crowd, traffic, may be moving, but since the tripod is fixed, the lens view itself does not move.

The moving lens delayed photography, also called moving delayed photography, is based on fixed lens delayed photography, and by moving the position of a camera in the shooting, the effect of visual angle movement is generated, the moving lens delayed photography is a new technology, and due to the characteristics of double movement (scene movement and lens visual angle movement) and large time span (slowly changing things are concentrated into a few seconds), the picture is large and shocked, and often appears in various films.

At present, no particularly good method is used for realizing mobile time-delay photography, the prior art mainly comprises the steps of installing a camera on a tripod head for fixing, taking a picture, moving a tripod for a certain distance, then taking the next picture, moving the tripod for a certain distance, then taking the next picture, and the like, the defects of the prior art that the whole process needs manual operation, other measuring tools are needed for ensuring that the moving distances of the tripod are equal each time, the moving paths are straight lines (or continuous arc lines), if the moving distances of the tripod are not equal each time, the distribution of points shot each time in the whole path is not uniform, the time-delay film flickers suddenly and slowly, if the moving paths are not straight (or discontinuous), the time-delay film shakes, admittedly, even if the shooting process is well controlled, the method needs manual operation in the whole process, thereby wasting time and labor and having low efficiency.

Compared with the traditional mobile time-delay photography technology, the invention adopts a stepping motor to drive, adopts the control of a remote controller, and leads a driving pulley to finish the functions of moving, rotating, photographing and automatic time-delay photography, thereby saving the steps of frequently moving a tripod and photographing a camera in the traditional photographing process, having simple operation and convenient use, fixing a driving pulley and two driven pulleys on the stand feet of the tripod s1, then fixing the camera s5 on the tripod s4, and leading the driving pulley to drive the two driven pulleys to drive the tripod to move so as to change the visual angle of the camera, and the implementation flow of the automatic time-delay photography function is as follows: in the forward state F1, the driving pulley advances a distance s, which is called forward one step, in the shooting state F2, a shutter signal k is sent to control the camera to shoot once, in the waiting state F3, after a period of time t, the camera returns to the forward state F1 again, and so on, thereby completing the whole moving delay shooting process.

The invention adopts a remote controller based on wireless communication to control a control module 6 in a driving pulley driving body, which is also based on wireless communication and can receive wireless signals sent by the remote controller, then the control module controls a displacement motor 3 on a pulley body and a rotating motor 7 in the driving body to rotate forwards and backwards, the displacement motor drives a pulley 2 on the pulley body to move forwards and backwards, and move forwards and backwards by one step, the rotating motor drives a rotating body 10 to enable the rotating body to form relative motion with a driving body 5 and a pulley body 1 which are positioned below the rotating body, so that the driving pulley completes left and right rotation, the control module generates shutter signals for taking pictures to a data hole 8 on the driving body, and the data hole is connected with a camera shutter signal hole s3 through a data line s2, thereby controlling the camera to take pictures.

The remote controller function buttons and corresponding functions are as follows:

the forward step and the photographing function of the driving pulley are connected in series in a programmed mode to realize the automatic time-delay photographing function. The specific work flow of the automatic time-delay photographing function is as follows: after the remote controller presses the automatic time-delay shooting button, the driving pulley enters a forward state F1, namely, the forward state is one step s, then enters a shooting state F2, the control module sends a shutter signal k to the data hole, the shutter signal k is transmitted to the camera through the data line, the camera shoots once, then enters a waiting state F3, namely, a period of time T is waited, a time-delay shooting period T is formed, and the three steps of forward shooting, shooting and waiting are included in the time-delay shooting period T.

Since the speed of the rotation of the displacement motor is fixed, the time consumed for moving the motor one step s each time is t1, and since the photographing time is very short and can be ignored, the method comprises the following steps:

T=t+t1

in each time-lapse photographing period (T), the time T1 for each rotation of the displacement motor is equal, the time T for each stop is equal, so the period T is fixed, the distance s for each advance of the driving pulley is equal, and the time for the motor to stop is the waiting time T of the pulley.

The step range switch 9 on the driving pulley driving body can adjust the length of the single step range of the displacement motor, thereby adjusting the advancing distance s of each step of the driving pulley.

If the pulley repeatedly takes pictures in the period T, the pictures are played at the speed of 25 per second in the later period, and the moving speed of the pulley in the playing state is v, the relation between the single step length of the step range switch in different gear positions and the moving speed v of the pulley in the playing state, the motor rotation time T1 and the waiting time T of the motor in the playing state is as follows:

in a slow state, the shooting is carried out in a moving mode with the step length of 8mm, the later playing speed is 0.2m/s, the gear speed is slow, and the shooting method is suitable for delay shooting of small space slow moving in rooms, corridors, roadways and the like.

In a medium-speed state, the shooting is carried out in a 40mm step length moving mode, the later playing speed is 1m/s, the gear is a default gear, the speed is moderate, and the method is suitable for time-delay shooting of large-space fast moving in large factories or outdoor playgrounds, streets and the like.

Under the rapid state, the camera is moved to shoot at a step length of 200mm, the later playing speed is 5m/s, the gear speed is high, and the camera is suitable for shooting time-delay photography of large-scale movement of large buildings and the like in an open square.

Taking the medium speed as an example, a moving time-delay photographic lens which lasts for 15 seconds is shot, and the time consumption of the traditional method and the method adopting the invention is as follows:

	number of photographs	Required time of
			Time of use (min) in traditional method	375	450
When the invention is used (min)	375	20

Therefore, the traditional method needs 7.5 hours to shoot a 15-second time-lapse photographic lens, while the method only needs 20 minutes.
