PROBLEMS OF SOFTWARE PROCESSING OF DIGITAL PHOTOGRAPHY INTENDED FOR DETERMINING THE DIMENSIONAL ACCURACY OF A PRODUCT

Problems that arise during the processing of the acquired photo are analyzed in this paper. Different software packages were used to process digital photos in several formats. The required dimensional accuracy of the product in mechanical engineering is within the range of a few microns to 100 microns. The pixel size of the acquired product is calculated depending on the specifications of the camera sensor and the ratio in which the product occupies the surface of the photograph. By satisfying the stated condition, before determining the dimensional accuracy of the product, it is necessary to process the photograph and prepare the variables used in determining the accuracy of the product. The most commonly used software tools in image processing require binary photography, and its conversion into the binary form is required first. Conversion problems, and their proper solution, are key to successfully determining dimensional accuracy. Removing smudges on binary photos and rotating displays for photo overlap methods are problems that are solved in the paper. In some software packages, there is a problem connecting functions from different libraries. Proper resolution of these problems is an essential prerequisite for the preparation of variables to determine the accuracy of the product. The knowledge gained in this paper will help scientists and facilitate their software preparation and processing of photographs used to determine the dimensional accuracy of the product.
