With the development of visual measurement system  Normalize the measured coordinates into the same world coordinate system  Apply in the three coordinate measuring machine(CMM) to have the simulation experiment  So the data normalization has the advantage of more high precision. (2013) Trans Tech Publications  the visual measurement system of single camera which applied in the imaging theory of optical feature points  then get the global data  the result indicates that the maximum absolute tolerance between the normalization coordinates via the center of point set and the ones measured by CMM directly is 0.058mm  Switzerland.  it has been widespread used in the modern production. Due to the limit of the environment in scene  and achieve the overall measurement  the visual measurement system of single camera could not measure the shield between the measured objects each other. Focus on this problem  But the one between the coordinate repeatedly measured at the position of one network control point is 0.066mm  present a kind of the the knowledge of measurement network based on the visual measurement of single camera  set up the measurement network system via the multi-control points. Measure the optical feature points in every network control point via the visual measurement system of single camera  
Design of heliostats field for the scale of 1MW solar power tower plant (EI CONFERENCE) 会议论文  OAI收割

The development in basic technology and market strategy of solar thermal power techniques is booming rapidly due to the limited fossil resources and severe environmental problems all over the world. In this paper  the design method of heliostats field for the scale of 1MW solar power tower plant with latitude of 40.4N at the design point of the noon of spring equinox is introduced  which uses the multiplication of three efficiencies of cosine  atmospheric transmittance and intercept as the preliminary boundary limit to locate heliostats  while the spacing between heliostats is set not only for less shading and blocking  but also for the availability of installation and maintenance of heliostats. Furthermore  its optical performance tested by the software HFLD  is quite good  which has annual average efficiency of 71.36% and design point efficiency of 80%. 2012 IEEE.

Space camera imaging gain in-orbit adjusting strategy (EI CONFERENCE) 会议论文  OAI收割

A Multi-Step Gain Adjusting Strategy (MSGAS) of space camera was proposed  which was used to get higher SNR (Signal-Noise Rate) image. When the space camera working in poor light condition  the CCD signal was so weak that it's difficult to get a clear image  to reduce the quantization noise and improve the SNR  we must amplify the CCD signal first and then quantize. The MSGAS was achieved by adjusting the gain of the CCD (Charge Couple Device) signal processor step by step  the upper limit and lower limit were set  if the MDN (Mean Digital Number) of a fixed length image data was not between the lower and upper limit  the gain was adjusted step by step. In the experiment  the upper limit  lower limit and the step were set  and the result of the experiment showed that MSGAS was robust and SNR was improved from 28 to 39. 2009 IEEE.
