Description

Technical field

The invention relates to photography, volumetric photography, photography synchronization systems.

State of the art

The prior art devices for photographing an object from different sides in manual and automatic modes.

A device for creating three-dimensional photographs is known (RF patent 120250). The device consists of a rotary table, a photo-recording device, an electronic device with an installed control program and connection channels. The turntable consists of a rotary element and a base. The pivoting element rests on a shaft connected to a rotation mechanism. The control unit is integrated in the turntable.

The disadvantage of this device is the fundamental impossibility of organizing high-quality, uniform illumination of the captured object from below, since under the rotary disk there are structural elements that impede the passage of light to the captured object, which will inevitably lead to uneven illumination and the formation of extraneous shadows.

Illumination of the object being shot from below through the transparent or partially transparent base on which it is mounted can soften or completely eliminate unwanted shadows falling from the subject onto the base, as well as create the necessary black and white effects. Shadowless shooting is the most sought-after type of commercial subject shooting. Properly organized backlighting can replace the expensive post-processing process.

The task of organizing the lower backlight is solved in the following device closest to the invention.

A well-known photo studio with a rotary table (patent GB 2492111), in which the illumination of the removed object from below became possible due to the transfer of structural elements that impede the passage of light to the periphery of the desktop and the placement of light sources on the basis of the device.

The disadvantage of this solution is that light sources are pre-installed in this device, which in terms of power and color and temperature characteristics may not coincide with similar characteristics of the main lighting sources used for photography. This may result in incorrect color reproduction and a weakening effect of the low backlight. Preset light sources complicate and increase the cost of the device, whereas, in most cases, the photographer can dispense with his lighting equipment and / or reflectors and significantly expand the possibilities for realizing his creative plan.

Common disadvantages of the above devices are that these devices are not universal in terms of shooting objects with different mass and dimensions. They are designed for shooting objects whose mass and dimensional indicators lie in a narrow range. To expand the range without losing any functionality of the device requires the purchase of other devices designed for the weight and dimensions of the removed object, which leads to significant additional costs for the purchase, storage, maintenance and transportation of additional devices.

Disclosure of the invention.

The objective of the invention is the creation of a modular, easily transformable installation for circular photo and video recording of objects, weight and size characteristics of which lie in a wide range of values. In addition, the inventive installation is characterized by convenience in its transportation, storage and maintenance, as well as increased reliability and maintainability.

The technical result is achieved in obtaining the above advantages.

To achieve the specified technical result, a modular installation is proposed for circular photo and video shooting of objects, including a desktop rotation mechanism installed on the basis for placing photo and video shooting objects and made in the form of a disk; an image-recording device and a control unit based on a microcontroller connected via wired and / or wireless communication channels to an image-recording device and a rotation mechanism, while the rotation mechanism includes at least one active module configured to communicate torque to the worker a table, and at least two passive modules providing a support-stop function to the desktop, and placed on the base along the projection of the edge of the desktop; wherein the passive module includes a housing with a support roller installed therein, protruding at least part of its working surface beyond at least one wall of the housing to ensure interaction with the edge of the lower surface of the desktop; two thrust rollers mounted on one of the walls of the housing from its outer side with the possibility of interaction with the end surface of the desktop, and the active module is made similar to the passive one, and additionally contains sensors for the initial position and angle of rotation of the desktop, connected via wired and / or wireless channels communication with the control unit, and an engine or an engine with a gearbox, the output shaft of which is connected to the support roller, while the working surface of the support roller is equipped with a friction element.

The installation can be performed so that the axis of rotation of the thrust rollers are parallel and lie in a plane perpendicular to the axis of rotation of the support roller, while the thrust rollers are fixed at an equidistant distance from the axis of rotation of the support roller.

In addition, the housing, both active and passive modules, is configured to provide a stable position when a load is applied to the support roller, while the support roller is installed so that its projection onto the lower wall of the housing does not extend beyond it. For example, the housing can be made in the form of a parallelepiped, in the upper wall of which a hole is made for the protruding part of the support roller mounted inside the housing.

The housing of both the active and passive module can be equipped with fasteners from the side of its lower wall, made in the form of anti-slip spacers, or clamps, or double-sided adhesive tape, or plastic or metal clamps, or magnetic holders, or vacuum suction cups, or a bolt or screw connection.

Thrust rollers can be made with the possibility of tilting relative to its own axis and fixing them in the working position to ensure that the desktop is pressed against the support roller. Thrust rollers can be made in the form of truncated cones, expanding upward.

A DC or AC motor or a stepper motor can be used in the installation.

The initial position sensor can be made in the form of a magnetic key built on a reed switch or a Hall sensor, or an optoelectronic key, or a mechanical key.

In one embodiment of the installation, the sensor of the initial position of the desktop is placed between the thrust rollers on the upper part of the housing, and the angle sensor, made in the form of an encoder, or in the form of a mechanical, magnetic or optical key, is mounted on the output shaft of the motor or gearbox.

The installation can be performed in such a way that the support roller of the active module is connected to the output shaft of the motor or gearbox through an additional shaft, with two bearings mounted on it, mounted in the housing, while the support roller is mounted on an additional shaft between the bearings or on one side of the bearings , and the additional shaft has a rigid connection with the output shaft of the engine or gearbox.

The installation may contain at least one additional module, made similar to the passive module, but with the thrust rollers removed, mounted on the base under the desktop to compensate for the uneven load of the photo and video on the desktop.

The desktop can be made of light-transmitting material, and the rotation mechanism modules are equipped with at least four legs adjustable in height.

The implementation of the invention

The described setup for the circular photo and video shooting of FIG. 1 is modular and can be composed of a different number of active modules (3) and / or passive modules (4) and other components. The composition of the installation and the relative position of its parts depends, in particular, on the mass, dimensions, and other characteristics of the photo and video object (1). The principle of operation of the installation is considered on the example of the installation, which includes one active module of the rotation mechanism; two passive modules; a desktop (2), which is a disk made of light-transmitting material; a recording device (5), which is a digital camera; lighting devices (7), which are pulsed light sources (flashes), capable of synchronizing their work with the recording device through the wired or wireless communication channels provided for it (10); a control unit (6) connected via a wired communication channel (8) with the active module and through a wired or wireless communication channel (9) with a recording device.

Modules of the rotation mechanism can be installed on any flat surface, objects or groups of objects capable of ensuring their reliable fastening and proper positioning, for example, a table, one or more racks, stands, etc. Clamps, suction cups, double-sided adhesive tape and other fasteners provided for by the design of the module can be used as fasteners for the rotation mechanism modules.

Correct positioning is considered to be the position of the modules in which the working table rests on the support rollers (12) with the edge of its lower surface and abuts against the stop rollers (14) of all modules with its end, while the axis of rotation of the support rollers are parallel to the plane of the horizontally located working table. The presence of two thrust rollers on each module of the rotation mechanism guarantees a quick and correct arrangement of the modules and the working table relative to each other. This is ensured while the thrust rollers touch the end of the desktop. To ensure maximum stability of the working steel, the modules of the rotation mechanism should be placed in a circle evenly. Uneven placement of the modules around the desktop is allowed in order to increase the shooting angle and to prevent the modules from getting into the frame, provided that the desktop is stable with the shooting object installed on it.

To organize uniform illumination from the bottom of the subject, the modules are installed so that placed under the desktop, the light source can be considered not point relative to the subject.

Below is a more detailed description of the installation elements.

The passive module (Fig. 2, 3) performs a support-stop function, which consists in maintaining the desktop in a horizontal position and eliminating the displacement of the axis of its rotation while maintaining the possibility of free rotation of the desktop.

The passive module of the rotation mechanism includes a housing (11), one support roller (12), which, at least part of its working surface, extends beyond at least one wall of the housing, and two thrust rollers (14), fixed on one of the walls of the housing from its outer side. The support and thrust rollers are mounted on the respective shafts directly or using bearings.

The module case considered in this description is basically parallelepiped-shaped, but can also be made in the form of other geometric shapes and their combinations to solve specific design, technological and other tasks. To ensure the stability of the module when a vertical load is applied to it from the desktop and the subject, the casing is designed so that the projection of the support roller onto the lower wall of the casing does not go beyond it. The housing has holes for mounting fasteners.

There are various options for the layout of the passive module in terms of mounting and relative positioning of its constituent elements, while the relative position of the rotation axes of the support and thrust rollers remains unchanged. The axis of rotation of the thrust rollers are parallel and lie in a plane perpendicular to the axis of rotation of the support roller, while the thrust rollers are fixed at an equal distance from the axis of rotation of the support roller, and their relative position ensures that the edges of the lower surface of the work table are supported on the support roller and the end face of the work table both thrust rollers at the same time.

Possible options for the technical implementation of passive modules in terms of mounting the support roller are shown in (Fig. 2-9). The differences are in the locations of the bearings and the location of the support roller relative to the places of attachment of its shaft to the module housing or relative to the bearings mounted on the shaft:

- The shaft (20) (Fig. 2-5) can be mounted on two bearings (21), the outer cages of which are fixed in the housing of the module (11), and the support roller (12) is rigidly connected to the shaft and can be located with one the sides of the bearings (Fig. 2, 3) or between them (Fig. 4, 5).

- The shaft (20) (Fig. 6-9) can be rigidly fixed to the housing (11) using two fastening elements (24), and the support roller (12) is mounted on the shaft using at least one bearing (22 ), and can be located on one side of the fastening elements (Fig. 6, 7) or between them (Fig. 8, 9).

Possible options for the technical implementation of passive modules, in terms of the design of the thrust rollers are shown in (Fig. 2, 3, 10, 11). The differences are that:

- The support rollers are made in the form of a cylinder (Fig. 2, 3), this allows a quick change of the desktop;

- Thrust rollers are made in the form of a truncated cone, expanding upward (Fig. 10). The height of the rollers is selected so that their upper parts are located above the surface of the desktop. This design of the thrust rollers is aimed at preventing vertical displacement of the desktop;

- The shafts of the thrust rollers are made with the possibility of their tilt towards the desktop and fixation in the working position (Fig. 11). This provides additional stability to the desktop while maintaining the simplicity of its change.

The active module of the rotation mechanism (Fig. 12, 13) performs a support-stop function, which consists in maintaining the desktop in a horizontal position and eliminating the displacement of the axis of rotation, while maintaining the possibility of rotation of the desktop, and the function of communicating torque to the desktop using the engine installed in him.

The active module is similar to the passive one and additionally includes an engine (15) or an engine with a gearbox (16), a sensor for the initial position of the working table (17) and a sensor for the angle of rotation of the working table (19), and it may also differ in the way and place of mounting the support roller (12), while the working surface of the support roller is equipped with a friction element (13). The friction element serves to increase the coefficient of adhesion of the support roller to the worktable and can be a rubberized surface, one or more rubber inserts, etc. As the motor, a direct or alternating current motor or a stepper motor can be used.

Each of these engines can be equipped with a gearbox, which is its integral part, or connected to a gearbox, which is an independent mechanism. The need for a gearbox and its gear ratio are determined by the required rotational speed of the working table, its diameter, the diameter of the support roller and the speed of rotation of the motor output shaft, provided that the necessary torque is provided. Any of the considered combinations of the motor and gearbox are located inside the housing of the active module and are rigidly attached to it.

There are options for the technical implementation of active modules, in terms of mounting the support roller:

- The support roller is rigidly fixed to the output shaft of the motor or gear motor;

- The support roller is rigidly fixed to the output shaft of the gearbox. The gearbox is made in the form of a separate mechanism, the input shaft of which is connected to the engine;

- A support roller (12) (Fig. 13), is rigidly fixed to its own shaft (20) connected to the output shaft of the motor (15) or gearbox (16). The shaft of the support roller is mounted on two bearings (21), the outer cages of which are fixed in the housing of the module (11), and the support roller is rigidly connected to the shaft and can be located between the bearings or on one side of them.

To obtain information about the position of the desktop, the sensor of the initial position of the desktop (17) (Fig. 13) and the rotation angle sensor of the desktop (19) are installed on the active module.

The sensor for the initial position of the working table (17) is mounted on the housing of the module of the rotation mechanism (11) between the stop rollers (14) and can be implemented as a mechanical, optical or magnetic chopper, which, when passing over it, marks the initial position (18) on the edge of the lower surface desktop (2) generates an electrical signal read by the control unit via wired communication channels. Depending on the type of breaker used, the initial position mark is made in the form of a protrusion or recess closing the contact of the mechanical sensor, or in the form of a mark read by an optical element, or in the form of a magnet acting on a magnetic breaker.

The rotation angle sensor of the working table (19) is mounted on the motor shaft (15) or on the output shaft of the gearbox (16) and can be implemented as a mechanical, optical or magnetic chopper that generates one or more electrical impulses per revolution of the motor shaft or gearbox, read by the control unit via wired communication channels. Instead of a chopper, an encoder can be installed that transfers the value of the angle of rotation of the shaft to the control unit.

The desktop (2) (Fig. 1), is used to set the subject on it (1). The desktop is a disk made of a material that provides strength, rigidity necessary to absorb the load from the subject. The weight of the desktop should provide the necessary clamping of its lower surface to the friction elements of the support rollers of the rotation mechanism modules, in which there is no slipping of the desktop when torque is applied to it. To organize the illumination of the removed object from below, the desktop should be made of material that is fully or partially transmissive to light. Installation involves the availability of a set of interchangeable desktops that differ in size, strength, optical properties, price, etc.

The control unit (6) (Fig. 1) serves to control the operation of the installation elements and automate the shooting process. The control unit is a separate case containing a keyboard, display, connectors for connecting installation elements and other electronic components. The control unit is made on the basis of a programmable microcontroller and communicates with the engines of active modules and with sensors of the initial position and angle of rotation of the desktop via wired communication channels, as well as with a recording device via wired or wireless communication channels. The control unit allows you to set the desktop in the initial position using information from the corresponding sensor and track the angle of rotation by recalculating the information on the number of full and incomplete revolutions of the motor shaft through the gear ratio of the gearbox and the ratio of the diameters of the support roller and the circumference described by it during rotation along bottom surface of the desktop. When the desktop reaches the required angle of rotation, the control unit generates a signal for the shooting and transmits it to the recording device.

Lighting devices (7) (Fig. 1) are used to illuminate the subject and create a black-and-white pattern. As lighting devices use sources of constant and pulsed light. The choice of light sources and their locations for shooting is a difficult task, involving the addition or reduction of the number of sources used, as well as changing their location relative to the subject. Of great importance for the shooting is the consistency of light sources in terms of color temperature and power. The proposed installation for circular photo and video shooting does not have its own pre-installed lighting devices and involves the use of light sources available to the photographer, and does not limit it in their choice and location. When using a light-transmitting desktop, the design of the installation allows the backlight of the subject to be illuminated, since Elements of its design do not interfere with the passage of light.

The recording device (5) (Fig. 1) is designed to obtain images of the subject. As a recording device, analog or digital photos and video cameras can be used, as well as their varieties, including, but not limited to: web cameras, photo and video recorders, photo and video cameras of mobile devices, infrared, ultraviolet, high-speed and others special image capture devices.

As a recording device, a group of devices that simultaneously shoot an object from different angles can be used.

Other layout and usage options

The transformation of the device by quickly and easily adding or removing modules of the rotation mechanism and selecting the desktop of the required size, strength, transparency, etc., allows you to shoot objects with different weight and size characteristics.

The use of a worker has become large, allows you to shoot large objects, and installing a small desktop makes it comfortable to shoot small objects.

The use of additional active modules of the rotation mechanism allows you to tell the desktop more torque and shoot a heavy object.

The use of additional passive modules allows you to increase the stability of the desktop and distribute the load from the removed object to a larger number of modules.

When shooting especially heavy and large objects, additional support for the desktop may be required not only along its edge, but also over its entire area. To do this, use additional passive modules with removed thrust rollers (23) (Fig. 14). Depending on how the weight of the object is distributed over the surface of the desktop, the number and installation location of these modules is selected. The modules are oriented so that the axis of rotation of their support rollers are directed to the axis of rotation of the desktop.

The video mode differs from the photo mode in that a camcorder or its variants can be used as a recording device. The numerical values of the number of revolutions and the rotational speed of the desktop are entered into the control unit and video recording of the rotating object is made.

Manual shooting mode is also provided by the design of the proposed device. Manual mode is used in the absence of power supply, when using recording devices that do not have suitable channels for communication with the control unit, in the absence or breakdown of the active module, when shooting very heavy objects when there is not enough power from the available active modules. To implement manual mode, the installation is assembled according to a scheme similar to automatic mode, but active modules are not used. The desktop is rotated to the required angle and the object is shot manually.

Installation (Fig. 1) works as follows.

The photo and video object (1) is installed on the desktop (2), the recording device (5) is fixedly installed in front of it, the numerical value of the number of frames that will be produced by the recording device in one full revolution of the desktop is entered into the control unit (6). Based on signals from the control unit, the desktop is set in motion by the active module (3), which includes the engine, and the recording device takes a given number of shots and creates a sequence of frames for further use.

An example of a specific implementation of a modular installation for circular photo and video shooting.

A modular installation was made for circular photo and video shooting consisting of one active, two passive modules, a desktop, a control unit, a recording device, and two lighting devices. The desktop was made in the form of a disc with a diameter of 600 mm from clarified glass with a thickness of 12 mm. The glass surface was frosted on a sandblasting machine. When shooting, one lighting device was installed under the desktop, for the implementation of lower illumination of the desktop. The module housings were made of an aluminum profile pipe with a square section of 60 mm and a wall thickness of 3 mm. The length of the housing along the lower edge is 200 mm, along the upper edge is 170 mm. The diameter of the support rollers was 50 mm. The active module was equipped with a commutator motor with a reduction gear, providing a maximum rotation speed of the gear output of 7.2 revolutions per minute and providing a torque of 12 kg * cm. The output shaft of the gearbox was connected using a special coupling to the shaft of the support roller mounted on two radial bearings. At the same time, the maximum rotation speed of the desktop was about one revolution per minute. On the housing of the active module, between the thrust rollers, the ball houses a magnetic sensor for the initial position of the desktop, made on the basis of the K1116KP-2 microcircuit. The desktop angle sensor was made in the form of an optical chopper and is based on the GP1A50HR instrument. The control unit was made on the basis of the ATmega2560 microcontroller and contained a PWM collector motor rotation speed controller, a liquid crystal display with four lines of 20 characters each, 8 buttons as a control element and connectors for connecting to other installation devices. A Canon 5D MARK III digital camera was used as a recording device, and two Jinbei DM2 300 flashes were used as lighting devices. Several objects weighing 0.1, 5, and 20 kg were shot at a desktop rotation speed of one revolution in 1, 2, and 4 minutes . The rotation speed of the desktop was changed by the control unit using the PWM controller installed in it. As a result of shooting, sequences of frames of 12, 36 and 96 pieces were obtained for each object.

Also, similar tests of the installation were carried out with a working table with a diameter of 1.5 m and made of organic glass with a thickness of 20 mm.

Tests of the installation showed its ability to solve tasks.

The main difference and advantage of this invention lies in the ability to shoot both ordinary and large-sized and heavy objects. This versatility is achieved due to the fact that the main parts of the installation are made in the form of separate modules, the replacement and / or addition of which allows you to quickly and with low material costs to transform it to shoot a specific object. For shooting large or heavy objects, only additional modules are purchased and installed, and not the whole new device, designed for other weights and dimensions of the object being shot.

The modular organization of the installation ensures its reliability, high maintainability and easy transportation.

Modules in transport position, take up much less space than assembled a single device. Modules can be distributed among several transported groups, which allows manual transportation.

The design of the installation does not interfere with the passage of light to the subject from below, which makes it possible to organize a lower backlight for shadowless shooting.

To illuminate the bottom, you can use the lighting devices available to the photographer, and not built into the design of the device. The free choice of lighting devices, both constant and pulsed light, expands the possibilities of matching the lower backlight with the main lighting in terms of color temperature and power.
