Development of the Stepper Motor Control Module

At the enterprise where the pre-diploma practice was held, our department was charged with the task of developing a device for digitizing objects in three-dimensional models - a 3D scanner that would be suitable for serial production. The core of such a device is a module that controls the periphery of the scanner. It was possible to take a ready-made fee, but there was a requirement to make the device suitable for serial production. Therefore, it was decided to develop its own solution, which would be suitable for use in a 3D scanner. The device operates according to the principle of optical measurement of the distance to the object: two lasers installed at the edges of the object under study emit rays to the object being scanned, and the camera takes pictures of the place where the beam falls. Based on the resulting image, the distance to the model is calculated and a part of the 3D model of the object is built. But in order to obtain a complete model, it is necessary to remove the object under study from all points, for this purpose this object is located on a turntable, which is actuated by a rotary mechanism, which after each picture must rotate the object to a certain fixed angle, which allows it to be removed from all sides. For a well-coordinated work of lasers, a camera and a rotation mechanism, a module is needed that will control the operation of the device, its design was entrusted to me. The developed module should be simple and inexpensive to produce, easy to use, ensure stable operation of the 3D scanner.
