An Effective Tone Mapping Operator for High Dynamic Range Images
      
Simulation of natural daylight illumination determined by a high dynamic range image
      
The use of high dynamic range images as a source of the natural daylight illumination and a background for virtual scenes containing objects with complex optic properties (fabrics, automobile multilayer paints, etc.) is considered.
      
An analysis of the correctness of the available high dynamic range images is performed, and their drawbacks are discussed.
      
The modified illumination simulation algorithms make it possible to produce more accurate images; moreover, they are automatic, and robust with respect to errors in high dynamic range images.

The WSQ-1 Type Automatic Recording Water-Tube Tiltmenter is designed for continuous recording of secular ground tilt and earth tide observation.The tiltmeter has a float-arm structure. Temperature compensation has been taken into consideration in the design. The WQB-B-1000 type Electro-Eddy-current displacement transducer specially developed for the tiltmefer is a non-contact transducer with high sensibility, wide dynamic range and high stability and less requisites in direction guiding of the float. The transducer not only simplifies the structure of the tiltmeter but also ensures its good quality. The tiltmeter output represents the water level difference and sum in the two water vessels. The difference gives the tilt signals which are to be measured while the sum indicates not only of the stability of the tiltmenter but also act as signal when the it is calibrated by means of a calibrator fixed at the center of the water tube. Actual test results show that the scale value of the WQS-1 tiltmeter is better than 5×10-9 rad/mm (when the water tube is 30 meters long), average zero drift is better than 3×10-9 rad/day, measuring range is ± 1mm (no readjustment needed) and the accuracy of measurement of the tidal factor r reaches 0.003 (M2. 88 davs).

为了连续记录地壳长期倾斜运动和进行固体潮的观测研究,我们设计制造了 WSQ-1型电涡流自记水管倾斜仪.该仪器缸体采用浮子——横臂结构,并在设计中考虑了温度补偿.为本仪器专门研制的 WQB-B-1000型电涡流位移变换器是一种非接触式传感器,它具有灵敏度高、动态范围宽、稳定性好、对浮子导向要求低等优点.这种传感器的采用,简化了仪器结构,并保证了整机的良好性能.仪器输出两缸体的水位差与水位和信号,前者即测得的倾斜信号,而后者不仅作为整机稳定性指示,而且在利用位于水管中央的标定器进行标定时作为标定信号.测试和试记录证明,仪器格值优于5.10~(-9)rad/mm(水管长度30m),测量水位差范围±1mm(不需调整),平均漂移优于3·10~(-9)rad/日,记录固体潮γ因子精度达0.003(M_2波,88天).
