Is it possible to create such a device based on Arduino?

Question

Arduino

Hello!
Description:
There is such a way of shooting as combined shooting. For example, the camera is placed on a tripod, first we shoot a person so that he is always on the left. In the next passage, we remove it so that it is all the time on the right. Then, at the editing, we stitch two frames - we get a combined frame of two people, where they are played by one actor. The disadvantage of this method is that the camera must be directly located strictly on a tripod. No wires, panoramas. Otherwise, it will be almost impossible to stitch the frame because the background is static.

Task:
It is necessary to assemble such a device, where it will be possible to set the speed and angle of rotation. Those. the camera clings to a tripod, where it is possible to turn the tripod head strictly in a given interval, for example, 30 degrees in 1 minute. This is necessary in order to achieve the camera wire when shooting in combination. Those. we remove the wire of the first scene, then exactly the same in the second scene. The result is a combined dynamic shooting.

PS: Professional equipment that performs such a task is expensive. Shooting on chroma key is not possible due to technical reasons.

Question, please tell me, is it possible to create this, let's say using a regular Arduino kit, let's say this?

The task is precisely to write the program. Sew it into the Arduino. Display the buttons ± for angle, ± for time and, for example, the Start button.

Thanks for any answer!

Answer 1

Your main problem is mechanics.
Even having assembled on the basis of any microprocessor (at least connect stepper motors to the same ordinary computer via LPT through the driver), your design may introduce errors - i.e. a tooth in the gearbox jumped off, the 'beam' bent, but a tritely different temperature, etc. thermal expansion and the camera is already looking in the wrong direction.
In expensive positioning systems, these errors are removed by feedback (the angles are read after the gearbox) and high-quality components (durable and lightweight materials).
If you want to collective farm, you need to invent cheap feedback (so that the program knows which engine to turn on to correct the situation).
I can offer the simplest and most original one - to fix a laser pointer / or mirrors that reflect its light in such a way that the movement of the light spot along the walls of the room (it is better to build special screens with the right angles to facilitate calculations) and the position of this spot to track with a video camera and very simple software (you can even write it on an arduino by reading information from a video sensor that receives an image through a light filter matched to the color of the pointer, google 'arduino light source tracking') or adapt an ordinary computer and several cheap webcams for this (the choice of which is determined by speeds, with which the camera will rotate)
The number of laser pointers is selected according to the number of freedoms in which the camera must move, for example, two freedoms (turn up / down, left / right) - one beam.
ps A slightly more complex circuit, designed in the form of an end rotation sensor, may be slightly different - a rotating mirror installed in a rotary hinge reflects the beam into a pipe, which is also a stiffening rib or the tripod itself, at the end of which the sensor, the second sensor is fixed at the mirror and catches the exact number of revolutions. As a result, the delay between the signal at the speed sensor and the sensor at the end of the pipe will determine the angle of inclination. Such a scheme is very accurate, but the rate of reaction depends on the speed of rotation of the mirror.

Answer 2

The software part here is written in an hour (if you have never programmed at all). The main difficulty is to assemble the mechanical part, it seems to me. And you will need a stepper motor, as far as I understand, I will conceive (look for a step motor on eBay). On the contrary, you do not need such a set. Enough arduina, stepper motor, strapping (PSU and motor driver).
Answering the question itself: yes, you can create such a device based on Arduino.

Answer 3

I think it's quite possible. You will need to design a rigid frame for the camera.
It also seems that the cost of professional equipment is due, not least, to the accuracy of the servos.
That is, as usual, instead of money, you will have to sacrifice time by ordering different servos and testing them for accuracy, or looking for some reviews of specific motors.
