    摘要:

    为分析琉璃瓦非接触式颜色测量中 不同测量条件对测量结果的影响,以X-Rite Spectro Eye分光光度计测得的数据为标准值,用非接触式颜色测量设备PR705光谱辐射度计获取琉璃瓦碎片的颜色信息,以不同的照明距离、测量距离、仪器曝光时间为试验条件,色差为试验指标,进行单因素试验和正交试验,并对试验结果进行极差分析与方差分析。试验结果显示:测量值与参考值的色差最小为1.0220,最大为1.6510,影响试验指标的因素主次顺序为照明距离、仪器曝光时间、测量距离,琉璃瓦非接触式测量参数的最优组合为照明距离1.5 m、仪器曝光时间2000 ms、测量距离1.0 m;最优测量条件下,色差更小,仅为1.0143。

    Abstract:

    In order to analyze the influence of different measurement conditions on the measurement results of non-contact color measurement of glazed tiles, the data measured by X-Rite Spectro Eye spectrophotometer was used as the standard value, and the non-contact color measurement equipment PR705 spectroradiometer was used to obtain the color information of glazed tiles. Single-factor tests and orthogonal tests were performed by taking different illumination distance, measurement distance, instrument exposure time as the test conditions, and the color difference as the test index, then the test results were analyzed by range analysis and variance analysis. The test results showed that the minimum color difference between the measured value and the reference value was 1.0220 while the maximum was 1.6510. The primary and secondary order of the test factors affecting the test indicators were the illumination distance, the exposure time of the instrument, and the measurement distance. The optimal combination of non-contact measurement parameters for glazed tiles was an illumination distance of 1.5 m, an exposure time of 2000 ms, and a measurement distance of 1.0 m. Under the optimal measurement condition, the color difference was as small as 1.0143.
