Nowadays the appearance of publications, scientific and research, and also research and development works on the creation of video monitoring systems for rocket and space technology products is caused by a well-known fact about the most reliable information channel — vision (human vision provides 95 % of information on surrounding objects), hence the inclusion of video information in the control system significantly increases the reliability of information from existing telemetry facilities of objects to track their normal functioning, as well as for rapid and unambiguous identification of the causes of abnormal and emergency situations that occur during the flight of rocket and space technology products. The article proposes a method for processing information from a video telemetry system about the temperature of thermally loaded elements of launch vehicles and upper stages by a remote contactless method with visual representation by converting a signal received from video cameras based on the principle of color pyrometers and Planck distribution. To implement the algorithm for processing video information for calculating the temperature, a block diagram of the solver is developed. A method for presenting video information and temperature measurements is presented provided that there is a color video image with a reduced frame rate and wide spectral range.
