Abstract

The common examinations of distant objects colors are realized with digital post processing of picture. Therefore, results of examinations are delayed. Consequently, real-time measurements of medium distance objects color taking place on the skyline have been examined. The medium distant objects that are under investigations are a different type of skyscrapers positioned at distant from 1 km to 3 km. Examinations were performed at the same time with two types of color sensors. These sensors are TCS3200 and VEML4060, they differ in dimensions, photonics characteristics and data transmission type. Therefore, to carry out the examinations, a standalone measurement system based on Nucleo64 board has been programmed. The data sampling ratio was 250/s. Sensors calibration was performed with the laboratory set-up consist of the specialized light sources, monochromator, fiber optic light divider and optical power meter. During medium-distant objects color examinations sensors were connected with monocular. Mentioned objects optical spectra characteristics were referred to data obtained with spectrophotometer use. Obtained results pointed that the use of an optoelectronic color sensor and a commonly available optical system with a fixed focal lens enables real-time measurements of objects’ colors located on the skyline. The VEML6040 sensor shows better agreement than TCS3200 with spectrometric characteristics of distant objects.
