Key Points

Temperature measurement accuracy improved to within ±0.1 °C, enhancing reliability for practical applications.
By applying image preprocessing, errors from color variation and surface defects on thermochromic liquid crystals were minimized.
Assessment involved capturing scattering light intensity data from surfaces covered with thermochromic liquid crystals.
Findings indicate that artifacts in temperature distribution previously seen are eliminated, yielding more precise results.
