Finally,the dimensions of the illuminator were optimized based on the irradiance model.

最后，根据简化的照度模型对光源的几何参数进行优化。

In order to detect light energy while keeping illuminator in a sealed box,an optical safety cover is designed.

Finally, the paper presents anti-jamming specific methods and measures of the impact of illuminometer performance.

最后，提出了影响照度计性能的抗干扰的具体方法和措施。

These index we need first-level illuminometer, color measurement instrument to detect.

以上这些指数我们需给用甲等照度计、测色仪来检测。

The research technique used in this design mainly include the literature reading, consulting expert, the questionnaire survey, the scene investigation, survey and so on, the instrument which used in the survey is illuminometer.

In the matching stage, the angle of feature vectors is used as the similarity measure in the high dimensional space directly. This similarity measure is invariant to the linear transformation of feature vectors. Compared with SIFT and normalized correlation, the proposed method needs no primary features such as edges, corners, gradient or shapes which are very unstable in low contrast and low NSR images.

在匹配过程中，以向量之间夹角的大小作为相似度度量，直接利用图像的灰度信息在高维向量空间中考虑图像之间的相似度，克服了在低照度、低信噪比的图像中求边缘、角点、梯度和形状等特征的困难，不受向量模大小以及向量平移的影响，即相似度的计算是线性光照不变的。

For a moderate image illumination, the electronic shutter time of CCD camera was adjusted by external trigger and the aperture of iris diaphragm was adjusted by motor controlled by single-chip.

采用外触发方式实现CCD摄像机的电子快门时间调节，由单片机控制电机调节可变光阑的通光口径，以使像面照度适中。

Application of vector method to the calculation of space target ground irradiance［J］.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
