Description

Camera carriage and recording system

The present invention relates to a remotely controllable camera dolly and a system for television, film or video recordings with the remotely controllable camera dolly.

During the production of television programs, films, video recordings or live broadcasts, it is often desirable to maneuver one or even more cameras between different shooting positions. The camera movements required for this may include a change in a height of the respective camera, a lateral and longitudinal movement between the camera and a photographic object, and a change in a camera orientation to the photographic object. In addition, it is often desirable that the moving camera can also take pictures of an action or scene. For such a camera movement, mobile camera carriages with a corresponding camera mount can be used, which ensure a sufficiently stable platform for the camera both at rest and during movement, so that image blur in the recording can be avoided.

The currently used mobile camera carriages or systems are very large and therefore hardly usable on a stage. Even in front of the stage, the size and height can be a problem, as valuable auditorium and the free view are partially restricted, which is undesirable for organizers and spectators of concerts and shows. In addition, these systems are often very expensive.

In view of the above, the present invention proposes a remotely controllable camera dolly according to claim 1, a telemetry system for television, film or video recordings according to claim 12 and a studio or stage system according to claim 20.

According to one embodiment, a remotely controllable camera dolly is provided. The camera dolly comprises a flat first base body, at least four first wheels connected to the first base body and their respective axes of rotation parallel to each other, and at least four second wheels connected to the first base body and their respective axes of rotation in a first plane are substantially orthogonal to the axes of rotation of the at least four first wheels, such that the camera carriage can be moved over the at least four first wheels and the at least four second wheels guided along a guide element. In addition, the camera dolly comprises a motorized camera mount detachably connected to the first main body and pivotable in at least two axes.

The guide element is typically a rail system with at least one double-rail track with two rails spaced apart from one another with a typically rectangular cross-section, the camera carriage being mountable on the rail system in such a way that the inner sides of the two rails are at least two of the at least four first wheels are touched and that the tops of the first rail and the top of the second rail are contacted by at least two of the at least four second wheels. Typically, for this purpose, the four first wheels are arranged below the first plane and / or the four first wheels are arranged in the direction of an axis of rotation of at least one of the four second wheels between at least two of the four second wheels. With this structure, the at least four first wheels can serve as guide wheels while the at least four second wheels receive the weight of the camera dolly. This allows a safe, non-slip and sufficiently low-vibration movement of the camera dolly on the rail system, in particular, when the at least four first wheels and / or the at least four second wheels are designed as rollers, which increases the contact surface on the rail system.

To further improve the smoothness of the camera dolly, the at least four second wheels are also typically mounted in pairs over a common axle or individually damped.

In addition, the at least four first wheels and / or the at least four second wheels are typically provided with an elastic material, e.g. A PU plastic, frosted, which also the running smoothness of the camera dolly can be further increased.

Typically, the at least four first wheels are resiliently mounted in a direction orthogonal to their respective axis of rotation. As a result, the camera carriage can be guided resiliently mounted between the inner sides of the two rails and so the smoothness and the lateral stability of the camera dolly can be further improved. In this way, the requirements for smoothness and stability of the camera carriage during the recording can be significantly increased compared to video surveillance system and so the corresponding criteria of the film and television industry are met.

In addition, the camera car can be constructed very compact or compact. Typically, the volume of the first body is less than about 2 liters, more typically less than about 1 liter. In particular, the distance between the top and the opposite bottom of the dolly may be only about 7 cm, or even less. The low height of the camera dolly makes it possible that the camera dolly visually does not disturb the show or recording, or at least hardly disturbs it. In addition, the compact design of the camera dolly also allows safe and quiet guidance of the dolly in relatively tight bends.

This considerably expands the possibilities of use of the camera dolly or of a pick-up system comprising one or more camera carriages and a correspondingly dimensioned rail system. In addition, the costs can be reduced.

At concerts, performances and shows, especially in large arenas, the staging increasingly includes the transfer of stage action to well-visible screens. Only in this way can all spectators participate on equal terms and can be justified expensive tickets. Numerous, even smaller concerts for TV broadcasts and for sale on DVDs with cameras are recorded in parallel. Increasingly, music and stage formations are having their next, new appearance for DVD, BlueRay, online, and / or TV exploitation scanned. However, the fully or partially automated camera systems used so far are very large and therefore can not be used on stage. In addition, sensitive artists can be disturbed by large recording technology or camera staff on stage. In turn, the previously used systems in front of the stage are often obstructive due to their size and height. In addition, they occupy a relatively large space, which is why the organizer is often forced to sell fewer tickets or, in the worst case, already existing on-site viewers to implement inferior seats, because in practice, the order for a recording is issued only then if it is clear that the respective arena is sold out. Furthermore, the risk is very high that in the mostly darkened atmosphere cables can become trip hazards, which can lead to technical faults.

All these problems can be at least significantly reduced by using the small-volume camera dolly in this document. Since they require less space and limit the visibility much less, the cameras can be remotely operated on and / or in front of the stage. Thus, the quality requirements of the production company or the audience on the screen (TV, DVD) with the needs of the organizer or the live audience can be better reconciled with each other and so conflicts of interest largely avoided. It also allows for more dynamic image capture from the moving dolly. After all, the small camera carriages are cheaper to produce and transport and on the other hand, the assembly and disassembly of the corresponding recording systems is typically easier.

Typically, the visible surfaces of the first body and the camera support are blackened, and both the at least four first wheels and the at least four second wheels are frosted with a black, elastic material. For example, the first body may consist of appropriately anodized aluminum. As a result, the camera dolly is optically even less visible during the show or recording. Also, unwanted light reflections can be largely avoided.

According to a development, the camera holder can be fastened to the upper side and / or on the underside of the first basic body. This allows a simple change of the camera mount or a system of camera (s) and camera mount ("remote head") which is typically adapted to at least one special camera.

The camera mount can be set up to record one camera or two cameras or be designed as a corresponding "remote head." The use of two cameras enables the recording of 3D movies or 3D videos -by-side ") or orthogonal by means of mirror setups (" mirror ") to each other.

For example, the first base body having a plurality of corresponding mounting holes on which the camera mount can be attached, for example, be screwed can. The mounting holes may be arranged in a grid and / or have different diameters, whereby the flexibility is increased. About the mounting holes and other additional modules can be attached to the first body. However, it can also be provided that the first base body has interchangeable plates or sections, via which the camera holder can be connected to the first base body.

Typically, the camera mount is mountable on both the bottom and the top. This allows the camera dolly with both over the two-rail track guided camera, z. Near the ground or slightly elevated, as well as with the under-track camera (overhead), e.g. near a blanket, to move. For example, several camera carriages can be used on corresponding two-rail tracks at different heights and thus different image perspectives are made possible.

According to a further development, an electric motor, e.g. a brushless DC motor arranged to drive at least one of the at least four second wheels. Alternatively or additionally, the electric motor can also be used to drive at least one of the at least four first wheels.

Typically, the electric motor is driven by a voltage source arranged in the first body, e.g. powered by a battery or a battery pack that can also supply the camera mount as well as the camera and other modules.

The electric motor can be connected to the at least one of the at least four second wheels via a reduction gear arranged in the first basic body. As a result, a sufficiently large torque for driving the camera carriage can also be made available for torque-weaker electric motors, so that the camera carriage can change its position quickly and even carry possibly existing supply and / or data cables. When using an electric motor with high torque can be dispensed with a gear reduction completely.

The inventors have surprisingly found that the camera carriage with high reproducibility and smoothness can be moved with only one driven second wheel on the two-rail track. In these embodiments, a planetary gear may be interposed between the electric motor and the driven second wheel rather than the otherwise typically used. Differential gears used to be used or even completely dispensed with a gear reduction, if the electric motor used provides a sufficiently high torque. This allows a particularly simple and small-volume construction of the camera dolly.

Typically, the camera dolly is constructed so that its center of gravity is as deep as possible, e.g. lies below the at least four second wheels. For this purpose, a weight plate arranged below the first plane or even below the at least four second wheels may be provided in the first base body. Alternatively or additionally, a weight plate may be arranged on the upper side of the first basic body.

According to a development, the camera carriage has a connection for a supply cable for the electrical power supply of the electric motor, the camera holder, the camera and / or further modules, and / or for the transmission of video and / or audio signals of the camera, control data and / or position data. Typically, the port is located, e.g. one or more connectors, for the supply cable laterally on the first body, e.g. between two of the four second wheels, so that the supply cable can be dragged along by the camera dolly laterally next to the double-rail track. The connection can also be located at the top of the first body.

Typically, the supply cable is a data cable for transmitting image and / or sound signals of the camera, which are also referred to below as video signals, control data and / or position data. The control data typically includes control data for the camera mount and the camera and / or control data for the camera carriage, such as control data for the electric motor or instruction to a motor control, so that the camera carriage moves to a new position on the two-rail track and / or according to a speed or a temporal speed profile on the two-rail track moves. The position data may include positions to be approached by the camera carriage and sent to the camera carriage and / or current positions of the camera carriage determined by the camera carriage and transmitted by the camera carriage. To determine its current position, the camera dolly may have a sensor and / or a transmitter. For example, a laser, radio, or ultrasound-based positioning system may be used. To determine the position, motor data, for example the rotational speed, can additionally or alternatively also be used. Alternatively or additionally, the camera carriage may have a wireless transmission system for the image and / or sound signals of the camera, the control data and / or the position data.

According to a further development, the camera dolly comprises a flat second base body, which is pivotably connected to the first base body, at least four further first wheels, which are connected to the second base body and whose respective axes of rotation are arranged parallel to each other, and at least four further second wheels, which are connected to the second base body and whose respective axes of rotation are arranged in a plane which is substantially orthogonal to the axes of rotation of the at least four further first wheels.

However, the first base body can also consist of two or more flat partial bodies, which are pivotable in the first plane to each other, wherein each of the at least two flat body part in each case at least two first wheels and at least two second wheels are connected.

This allows a two- or multi-part construction of the camera carriage from typically similarly constructed camera dolly sections. As a result, the flexibility of use can be increased, the camera carriages are built very small and can also be guided around very tight bends.

Typically, in the connected state, the second basic body or a second partial body projects, at least in a plan view, partly into the first basic body or into a first partial body when the second basic body and the first basic body are connected. In addition, the second basic body or the second partial body is typically connected to the first main body or the first partial body via a short supply cable for supplying energy and / or for transmitting video signals, control data and / or position data connectable or in operation. As a result, the modules or functional units can be divided into two or more camera carriage sections. Thus, only one of the main body or the partial body may have an electric motor. According to another embodiment, two or more synchronized electric motors are used, which may be located in different basic bodies. According to one embodiment, a system for television, movie or video recordings is provided. The system comprises at least one camera dolly and a rail system having a first rail and a second rail spaced apart according to a track width, the first rail and the second rail each having a top and an interior, each substantially straight in a cross section , The camera dolly comprises a flat first base body, at least four first wheels connected to the first base body and their respective axes of rotation parallel to each other, and at least four second wheels connected to the first base body and their respective axes of rotation in a first plane which is substantially orthogonal to the axes of rotation of the at least four first wheels, wherein the camera carriage is placed on the rail such that the inner sides of the first rail and the second rail are touched by at least two of the at least four first wheels and the top of the first rail and the top of the second rail are each contacted by at least two of the at least four second wheels. In addition, the camera dolly comprises a motorized camera mount detachably connected to the first main body and pivotable in at least two axes.

Typically, the first rail and the second rail are profiles, e.g. Steel or aluminum profiles, with a substantially rectangular cross-section. These are on the one hand cost-effective and on the other hand allow stable guidance of at least one camera dolly. Typically, the first rail and the second rail are blackened, e.g. Anodized accordingly, so that even the rail system neither the recording nor the live viewer noticeably disturbs directly and unwanted light reflections can be largely avoided.

In accordance with the typically small size of the at least one camera dolly, the gauge between the two rails is typically less than 20 cm, more typically less than 15 cm.

In order to ensure the highest possible stability, the center of gravity of the at least one camera dolly is typically below the upper side of the first rail and the upper side of the second rail when the at least one camera dolly is arranged on the rail system. In addition, the first body extends to a maximum of about 7 cm the top of the first rail and the top of the second rail when the at least one camera carriage is disposed on the rail system.

According to one expanse, the system includes at least one camera receivable from the camera mount with a volume without optional optical attachment of about 0.25 liters or less. Typically, the camera is capable of delivering video signals at a data rate in excess of 100 Mbps, typically greater than 1 Gbps. This allows for high resolution images, typically at least in Full HD (High Definition, i.e., 1920x1080 pixel image resolution at 50Hz or 60Hz). For example, it can be a 2/3-inch camera from the manufacturer IndieCam, but the camera can also be a mobile phone with a high-resolution camera, such as a Nokia 808 Pure View with a 41 megapixel camera Mobile phones with high-resolution camera can be powerful, very cost-effective recording systems provide, with supply cables may even be completely dispensed with, since modern mobile phones can be controlled via radio and provide video data and also have sufficient computing capacity to take control tasks for the camera car ,

According to a further development, the system for television, film or video recordings comprises a positioning system for determining a position of the at least one camera dolly. This can be a laser-based, infrared-based or ultrasound-based positioning system.

According to yet another development, the system comprises a control panel for controlling the position of the at least one camera carriage, an orientation of the camera holder and / or a camera setting, a control computer for controlling the position of the at least one camera carriage, an orientation of the camera holder and / or a camera setting, and / or a monitor for displaying at least one camera image. In particular, for repeatedly repeated performances, the control computer can take over the control of the camera car and the cameras fully automatically, so that an intervention of the director or the stage manager only in case of disturbances or unforeseen events is required. According to another embodiment, a studio or stage system is provided. The studio or stage system comprises a bottom with a slot and / or a ceiling with a slot and a system for television, film or video recordings with at least one camera carriage and a rail system with a first rail and a second rail for the at least one camera dolly such that the camera mount extends at least partially through the respective slot when the at least one camera dolly is placed on the rail system.

In this way, the rail system is not visible from the stage and the auditorium and, at most, still parts of the camera mount and the cameras can be recognized by the camera carriages. In this way, the needs of performance and recording of the performance can be even better reconciled. In addition, any supply cables for transmitting image and / or sound signals of the respective camera, control data and / or position data under the floor or over the ceiling can be arranged. As a result, tripping hazards and thus caused injuries and / or technical disturbances can be avoided.

Further advantageous embodiments, details, aspects and features of the present invention will become apparent from the dependent claims, the description and the accompanying drawings. It shows:

1B is a plan view of a system for television, film or video recordings with a camera carriage according to an embodiment;

2 is a plan view of a system for television, film or video recordings with a camera carriage according to another embodiment; and

Fig. 3 is a side view of the system shown in Fig. 2 for television, film or video recordings according to another embodiment. The term "flat body" as used herein is intended to describe a body that extends in at least one direction, typically in two mutually orthogonal directions, by a factor of at least 3, typically at least 5, greater than in one has substantially vertical direction.

The term "camera" as used herein is intended to include both a film or video camera, in particular an at least full HD capable film or video camera, as well as a combination of a film or video camera and an additional optical attachment, such as a lens system, as well as an integrated system of film or video camera and additional optical attachment include.

1A shows a schematic side view of a remotely controllable camera dolly 100. In the exemplary embodiment, the remotely controllable camera dolly 100 has a flat first base body 10, to which eight first wheels 1 are connected via respective axles 4. The respective axes of rotation (dashed arrows in Fig. 1A) of the first wheels 1 are substantially parallel to each other. Of the eight first wheels 1, however, only four can be seen in FIG. 1A whose axes of rotation lie in one plane and which obscure the other four first wheels. In other embodiments, four, six or even more than eight first wheels 1 are connected to the first base body 10. In addition, four second wheels 2 are connected to the first base body 10, of which only two are visible in Fig. 1A. The axes of rotation of the second wheels 2 are arranged in a first plane 21 substantially orthogonal to the axes of rotation of the first wheels 1, such that the camera carriage passes over the first wheels 1 and the second wheels 2 along a guide element, typically up and down a rail system, guided can be moved. In addition, a motorized camera mount 30, which is pivotable in at least two axes, is detachably connected to the first base body 10, e.g. via screw connections, in or on which a camera can be detachably fastened or in which a camera is integrated. Camera mounts are known per se, therefore, has been omitted in Fig. 1A for reasons of clarity on a detailed representation of the camera mount 30.

The first base body 10 may have a substantially rectangular cross-section, for example, be a substantially flat cuboid, wherein corners or edges may be rounded. The first base body 10 may also consist of a plurality of flat partial bodies. Typically, the first body 10 extends between the two rows of the first wheels 1, of which only one row is visible in FIG. 1A, to below the second wheels 2. This is illustrated in FIG. 1A by the dashed line 14. This structure allows the center of gravity of the camera dolly 100 to be set as low as possible, whereby the stability of the dolly 100 can be increased when it stands or travels with the second wheels 2 on rails. The first wheels 1 serve as lateral guides. Depending on the dimensions of the rails and the first wheels 1, the first base body 10 may even extend below the first wheels 1 between the two rows of the first wheels 1.

Typically, the camera mount 30 may be attached to both an upper surface 17 of the camera carriage 100, e.g. on the upper side 17 of the first basic body 10, as well as on or below a lower side 18 of the camera dolly arranged opposite the upper side 17, e.g. on the underside 18 of the first body 10, are releasably secured. This allows a simple conversion of the camera carriage 100 between a first configuration, in which the camera is guided over the first base body 10, and a second configuration, in which the camera is guided under the first base body 10. By using two or more camera carriages 100 in either one of the two configurations, e.g. On different high-mounted rails are moved, recordings can be combined from very different perspectives.

Fig. IB shows a plan view of a system 1000 for television, film or video recordings with the camera carriage 100, the track with its second wheels 2 on a two rails 50 with a first rail 51 and a second rail 52, which corresponds to a track width s spaced apart, are seated. For reasons of clarity, however, only a small part of the double-rail track 50 is shown in FIG. 1B. The rail system 50 may include one or more double rail tracks 50, each of which may have both straight and curved sections, and may even be located at different heights. One or more camera carriages 100 can be moved on each double-rail track 50, the first rail 51 and the second rail 52 of the respective double-rail track 50 each having an upper side (dotted areas in FIG. 1B) and an inner side 55 having a cross section in each case are substantially straight or have at least grade sections. This allows the respective camera carriage 100 to be placed on the rail system 50 such that the inner sides 55 of the first rail 51 and the second Rail 52 are each contacted by half of the first wheels 1 and that the upper sides of the first rail 51 and the second rail 52 are contacted by each half of the second wheels 2.

The first rail 51 and the second rail 52 may be profiles of substantially rectangular cross-section, e.g. Aluminum system profiles. This allows a cost-effective construction of the rail system 50.

Typically, the first rail 51 and the second rail 52 are blackened so that they are barely visible in the typically darkened recording environment. The first rail 51 and the second rail 52 may be e.g. be corresponding anodized profiles.

For this reason, the visible surfaces of the first base body 10 and the camera mount 30 are also typically blackened, and at least the first wheels 1 are frosted with a black material. Black tires may also be provided for the second wheels 2.

The tires of the first and second wheels 1, 2 are typically made of an elastic plastic such as PUR (polyurethane), whereby the stability, skid resistance and smoothness of the camera dolly 100 can be increased.

Typically, the first wheels 1 and the second wheels 2 are designed as rollers. This increases the contact area to the first and second rails 51, 52. As a result, the stability, skid resistance and smoothness of the camera carriage 100 can be further increased.

In addition, the second wheels 2 are supported attenuated via individual axes 3 or in pairs via a common axle 3. The second wheels 2 may e.g. corresponding miniaturized as truck wheels stored or suspended.

In addition, the first wheels 1 may be resiliently mounted in a direction orthogonal to their respective axis of rotation, ie in the direction of the axes of rotation of the second wheels 2 shown as dot-dashed arrows, such that the camera carriage 100 is supported by the first wheels 1 resiliently disposed between the first rail 51 and the second rail 52. As a result, the stability, slip resistance and smoothness of the camera gens 100 be increased. This also allows for smooth film or video recordings during the travel of the camera dolly 100 at typical speeds of up to about 4 m / s, even through curves with small radii of curvature below about 60 cm.

The track width s is typically less than 20 cm, more typically less than 15 cm. As a result, and by the typically small camera carriages 100 having a volume of the body 10 of typically less than about 2 liters, more typically less than about 1 liter, the system 1000 interferes with virtually no live performance nor recording.

In addition, the rail system 50 may be mounted under a floor and / or above the ceiling of a stage or studio such that the camera mount 30 extends at least partially through a slot in the floor or ceiling when the camera carriage 100 is seated on the rail system 50 is. As a result, the rail system 50, any supply cables and the largest part of the camera carriage 100 can be accommodated outside the actual stage, studio or auditorium.

For driving the camera dolly 100, an electric motor and optionally a reduction gear connected to the electric motor are typically arranged in the first base body 10. It was surprisingly found that the camera carriage 100 can be moved with high reproducibility and smoothness with only one driven second wheel 2 on the two-rail track 50. In this embodiment may be used between the electric motor and the driven second wheel 2, a planetary gear instead of the otherwise typically used differential gear or even completely dispensed with a gearbox.

According to one embodiment, in the first body 10 a voltage source, e.g. a battery housed to supply power to the electric motor and camera mount 30, as well as other modules or components, such as those shown in FIG. a sensor and / or transmitter for determining a position of the camera carriage 100, can be used.

For example, the position of the camera dolly 100 can be laser, radio or ultrasound-based. The camera dolly 100 may have corresponding transmitters, sensors or signal reflectors in these embodiments. If the double-rail track 50 is straight, the position of the camera dolly 100 may be determined by measuring the distance to a fixed point that may be at one end of the double-rail track become. This is frequently the case even with at least partially curved two-rail tracks 50, in particular if the position of the camera carriage 100 is determined regularly and / or if at least the approximate position of the camera carriage 100 can be determined from motor data. It can also be provided that the camera carriage 100 has a sensor for detecting position marks on the two-rail track 50.

As an alternative to using an internal voltage source, the electric power supply of the camera dolly 100 can also be effected via a supply cable. A connection for the supply cable can be located laterally on the first main body 10 or on the upper side of the first main body 10, so that the supply cable from the camera carriage 100 can be dragged laterally next to the two-rail track 50.

In the supply cable electrical and / or optical data lines for the transmission of video signals, control data and / or position data can be integrated. The supply cable can also be a pure data cable for the transmission of video signals, control data and / or position data.

However, at least parts of the video signals, control data and / or position data can also be transmitted by a radio module of the camera dolly.

The attachment of the modules on or below the base body 10 can take place via corresponding mounting holes.

In the exemplary embodiment, camera mount 30 is pivotable in two axes. A camera may be mounted on a receiving unit 30a of the camera mount 30 rotatably mounted about a shaft 31a to a rotary module 30b. In this case, the axis of rotation of the rotary module 30 is substantially perpendicular to the first plane.

Typically, the camera carriage 100 is constructed so that its center of gravity is as deep as possible, for example below the second wheels 2. For this purpose, a weight plate arranged below the first plane or even below the second wheels 2 may be provided in or on the first base body 10. In the exemplary embodiment shown in FIG. 1B, the first base body 10 is substantially rectangular in plan view. In other embodiments, the first base body 10 tapers at least in the top view. This is shown by the dashed line 13 in Fig. 1B and facilitates a compact two- or multi-part construction of the camera carriage from typically similarly constructed camera dolly sections. As a result, the versatility of use can be increased, the camera dolly can be made very small and can also be guided around very tight bends.

Thus, the camera carriage 100 may have a flat second base body, which is pivotally connected to the first base body 10 in its first plane. In this case, the second base body has at least four further first wheels, which are connected to the second base body and whose respective axes of rotation are arranged parallel to each other, and at least four further second wheels which are connected to the second base body and their respective axes of rotation are arranged in a plane which is substantially orthogonal to the axes of rotation of the at least four other first wheels on.

In the connected state, the second base body typically projects partially into the first base body 10. In addition, the second base body is typically connectable to the first base body 10 via a short supply cable for power supply and / or transmission of video signals, control data and / or position data connected. As a result, the modules or functional units can be divided into two or more camera carriage sections. Thus, only one of the main body or the partial body may have an electric motor, while in a further main body or partial body, a battery is housed. However, it can also be provided to use a plurality of synchronized electric motors in different basic bodies.

With reference to FIGS. 2 and 3, a similar system 1000 'for television, movie or video recordings with a camera carriage 100', similar to the camera carriage 100 explained with reference to FIGS. 1A, 1B and 2, will be explained two or more flat partial bodies 10A, 10B, which are pivotable with respect to. By the axes of rotation (dash-dot arrows in Fig. 2) of the second wheels 2 defined first plane to each other. FIG. 2 shows a plan view and FIG. 3 shows a side view. The two partial bodies 10A, 10B are typically connected to one another via a corresponding joint 12 and a short supply cable (not shown) for supplying energy and / or for transmitting video signals, control data and / or position data.

Typically, each of the flat bodies 10A, 10B has at least two first wheels 1, e.g. four first wheels 1, and at least two second wheels 2 on. This allows stable and quiet movement of the camera carriage 100 'on the rail system 50.

In addition, the second partial body 10B typically partially protrudes into the first partial body 10A. As a result, the camera carriage 100 'can be made very compact and the modules or functional units can be divided into two or more camera carriage sections.

In the side view shown in Fig. 3, the camera mount 30 is rotated in the clockwise direction by 90 ° about the rotational axis 31b of the rotary module 30b in comparison to FIG. In addition, Fig. 3 shows that the part body 10A, 10B and the body can be constructed of simple plates. Alternatively, the partial body 10A, 10B or the base body may at least partially consist of a milled base body.

Typically, the first body 10, 10A, 10B extends only up to a height h of up to a maximum of 7 cm above the top 56 of the first rail 51 and the second rail 52. This reduces the visibility of the camera dolly and increases its stability on the rail system 50th

In addition, the center of gravity of the mounted dolly is typically below the topsides 56 of the first rail 51 and the second rail 52, thereby increasing the stability of the camera dolly on the rail system 50.

The camera receivable by the camera mount 30 typically has a volume of at most 0.25 liters.

To meet the demands of professional recording systems, the camera typically can deliver video signals with a data rate of more than 100 Mbps, more typically more than 1 Gbps. This can be a professional, even digital, film camera. The camera can also be provided by a mobile phone be that can be releasably attached to or in a correspondingly executed camera mount 30.

The video data as well as the position data of the camera carriage (s), e.g. via respective data cables or wirelessly, fed to a control panel and / or a control computer for controlling the position of the at least one camera carriage, an orientation of the camera mount and / or a camera setting and displayed on a monitor.

Through the use of a control computer, a programmable system 1000 1000 'for television, film or video recordings, in particular a multi-camera synchronization system, can be provided. Several camera carriages can be programmed in such a way that their movements are synchronized with each other.

For example, the control computer may be or include a touch-screen programmer that can program all camera carriage and camera movements and other settings through a simple graphical user interface.

The movements may be time-based and / or event-based (e.g., after reaching a position). In addition, it can be provided to store the movement and adjustment instructions with a prioritization, so that different rules for the same camera can be combined with one another.

Typically, the control computer has an import / export interface to exchange driven and moving motion profiles with conventional PC devices.

As a result, a so-called motion control functionality can be provided. For example, processes and movements can be prepared before the actual production, which can then be adjusted in detail on site. For stage events with a fixed and rigid schedule, eg for classical orchestral concerts by score and opera performances, this means that the entire camera carriage and camera movements can be entered in advance. The motion control functionality also enables special trick shots for film, advertising and animation due to its high resolution and reproducibility. The movement data exported after the shoot was completed can also be further processed during post-production in 3D programs.

Since the fully automated System 1000, 1000 'can control multiple camera-equipped camera trucks, only one operator is required. This allows a correspondingly high cost savings compared to systems with one operator per camera - with the same number of cameras and perspectives.
