Color Acquisition And Analysis Based On Stm32 Microprocessor

The main content of this thesis is the design of portable color measurement method, which is proposed for testing the quality of printing products. In this paper, the basic theory of calorimetry, color detection principle and design method of color analyzer research, designed for printing color detection, and is suitable for portable color acquisition instrument accuracy. It is still not uneven in the view of the present market appeared a large number of printing quality at this stage some good and some bad color detection method and the appropriate test instrument. Starting from the actual situation, the basic theory and color chromaticity measurement based on technology, research and design a kind of color analyzer that can be directly read printing color quality information, you can directly read the measured object color information, and through the display module display color.This system is mainly included the color recognition system, data processing system and display system. These modules constitute hardware system design. Color acquisition system uses the digital interface of TCS3200’s latest acquisition as a color sensor, it can directly output digital signal frequency. The data processing system is based on 32 bit high performance microprocessor control chip STM32. The display system is used in TFT LCD display.Finally, Compiling and debugging the whole system process of program. Analyzing the collected data. Combining the hardware and program form color analyzer, and applied to the red, green, blue, white color card comparison, record the experimental results, the error analysis.
