为得到微环境参数对古建园林彩画色彩衰变量化影响规律,以颐和园为样本,选取颐和园典型彩画作为研究对象,并开发微环境参数监测系统,对彩画所处微环境信息进行全年实时监测,得到温湿度、风速及照度数据。同时,选取颐和园典型彩画进行周期性测试,提取彩画色坐标及亮度参数,并根据所采集的色彩信息计算出色彩的主波长及兴奋纯度,并拟合主波长、兴奋纯度、亮度随时间的衰变曲线。通过将微环境测试数据与色彩衰变曲线进行对比分析,发现温度、湿度、风速对彩画色彩影响较小,光照是造成彩画色彩衰变的主要因素,而且光照对彩画色相、亮度、兴奋纯度3个参数的影响程度不同,不同颜色受光照影响变化程度也有较大差异。
In order to get the influence of microenvironment parameters on the color decay of ancient landscape garden painting, take the Summer Palace as a sample, choose the summer palace typical color painting as the research object, and develop the micro-environment parameter monitoring system, Real-time monitoring, get temperature and humidity, wind speed and illumination data. At the same time, we select the summer palace typical color picture to carry on the periodic test, extract color picture color coordinate and brightness parameter, and according to the collected color information to calculate the color main wavelength and exciting purity, and fit the main wavelength, excitement purity, brightness with time Decay curve. By comparing the microenvironment test data with the color decay curve, it is found that temperature, humidity and wind speed have little effect on the color of the painted picture. The light is the main factor causing the color decay of the painted picture. And the illumination affects the hue, brightness, The influence of the three parameters is different, and the change of the different colors influenced by light is also quite different.
