Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Shown in Fig. 1, three-dimensional suspension movement control high-altitude of the present invention hangar system for shooting, it comprises lifting support 100, be arranged at lifting between the support rope 110 and be installed on vidicon camera 120 on the rope, described vidicon camera is connected with control gear 200;
As shown in Figure 2, described control gear 200 comprises computer controlling center, motor driver 230, motor 240 and encoder 250;
Computer controlling center comprises the computer 210 for information processing, and with the man-machine interfaces such as keyboard, touch screen and rocking bar that are used for the control command input that are connected with the computer input end, the output terminal of described computer is connected with some motor drivers;
Motor driver, the one end connects the output terminal of computer, and the other end connects and the control motor;
Motor, its rotatingshaft connecting rope is by rotating the position of regulating vidicon camera;
Encoder is connected with motor driver, for detection of speed and the rotation distance of motor and feed back to motor driver.
Image pickup method of the present invention is as follows:
Three-dimensional any-mode:
At some solid spaces, by pulling the rocking bar direction, control vidicon camera and do the arbitrary position and move along X, Y, Z axis, when rocking bar moves, the rocking bar signal is passed to computer, computer is respectively passed to four motor drivers obtaining data command by the CAN bus through calculating, and is gone to control again clockwise and anticlockwise and the speed of motor by motor driver, to reach the moving camera shooting effect of wanting, under this motion mode, be divided into a plurality of speed stages, but during each gear constrained motion the most at a high speed.
Three-dimensional preset mode:
At some solid spaces, X, the Y in space, the distance of Z axis have at first been calculated, data at computer interface input X, Y, Z, the calibrating camera origin position, and draw vidicon camera at the trajectory diagram of this space motion at computer interface, this trajectory diagram is that the mode with 3 D stereo is embodied on the computer desktop, is convenient to observe and revise.After finishing track, the operation computer software, computer is being transferred to respectively four motor drivers through the data of calculating with the CAN bus, driver receives after the data through judging, control clockwise and anticlockwise and the speed of motor, at this moment speed detects encoder and the speed that detects and range ability are fed back to motor driver makes comparisons, and carries out the control of effective running orbit and speed.In order to make vidicon camera when moving, not produce strong rocking, all adopt the damping method of operation when starting and stopping, slowly accelerating startup and stop with slow the deceleration, concrete damping range ability can be definite according to field conditions.
The three-dimensional simulation mode:
At a solid space, in the time can't determining the track of vidicon camera operation, can control vidicon camera with free running mode in advance by rocking bar.At this moment can use track recording function, at first record origin position, then just record at set intervals the position of vidicon camera on X, Y, Z axis No. one time by encoder, blanking time is shorter, and path accuracy is just higher.This track can be presented at computer interface at any time along with the motion of vidicon camera, when confirming that track meets the requirements, this track is stored, and vidicon camera is returned initial point, this moment operational outfit, vidicon camera will be by the track operation of recording.Can also preserve track such as needs.In order to re-use.
Two dimensional motion on plane:
Four motors can be distinguished arbitrarily and form a two dimensional motion mode on the plane by two, can do front and back, up and down, straight line, camber line and curvilinear motion, the motion mode that works alone, also can be the same with three-dimensional working method, do free-running operation, preset operation and dry run.
Actual effect of the present invention and meaning are:
This invention can use manpower to hang Wei Ya for shooting condition and tradition that most special occasions facilitates, especially do three dimensional motion in a space, so can finish the technical bottleneck that at present existing capture apparatus can not be finished, for example: we will take " Spider-Man " this class film, track up arrives him to want to allow the performer fly also always between housing-group, just have this equipment of employing only, it can finish the general utility functions of at present existing conventional capture apparatus, can reach again the shooting effect that existing capture apparatus can't be reached.In addition, can also shoot function can be made by oneself according to taking needs, the functions of the equipments upgrading can be done, for shooting brings larger intention space.
This equipment can also be applied in film ﹠ TV circles as high-tech stage property except hanging projection camera as the capture apparatus, replaces now in film ﹠ TV circles and large-scale performance activity the widely stunt stage property of use of institute---hang Wei Ya.And this equipment is because adopt wholly computer controlled or set running orbit by computer, or by movement locus of rocking bar Real Time Simulator, can do three-dimensional accurately motion in a space.So, the indigenous method of hanging the prestige Asia of using relatively at present manpower to draw, drag, this equipment provides the motion mode of more advanced and more accurate aerial hanging object.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
