Quality control during thermal spraying by computer processing of digital images

摘要

Thermal spray coating process comprises computer processing of digital camera images for associating similar intensity regions with symmetrical flat geometrical shapes. A thermal spray coating process uses a digital camera for detecting, controlling and/or monitoring process parameters which affect the sprayed layer quality, the image being computer processed for associating one or more regions of the same intensity and/or within a certain intensity range with one or more symmetrical flat geometrical shapes. An Independent claim is also included for quality control equipment for use in the above process.
