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

A calibration method of faint star magnitude of the star scene simulation device is proposed in this paper. In the research of simulation star magnitude
luminometers and CCD devices are the general calibration devices which are used to measure the illumination intensity and calibrate its magnitude. But if the simulation magnitude is only sixth magnitude
its illumination intensity is only 1.010-8 Lux. This illumination intensity level is the lowest illumination intensity that the commercial luminometer can detect. Hence the simulation star magnitude lower than six magnitude cannot be calibrated by luminoters. Likewise CCD devices also need an additive cooler in this case. When the single photon characteristic is presented due to the low luminosity of simulating light sources
the simulation star magnitude can be calibrated by detecting its photon flux of radiation with the method of single photon count. In this paper the detection principle of single photon based on a compact designed PMT detecting of the radiation level of simulation star magnitude is advanced. Especially a spectrum match method is proved theoretically to be an effective means for selecting PMT photosensitive type. In the case of the detection object of the simulation star in visible wavelength
a analysis indicates that the material of tri-alkali cathode materials its best choice after being compared the Signal-to-Noise of photon detector of several PMT photosensitive materials based on the different spectrum match ratio of different object light sources and different cathode materials. An experiment is employed to show the relationship of control voltage of PMT and its dark counter
the relationship of the environment temperature of PMT and its dark counter
which proves its only decades of CPS at room temperature. The so low dark counter avoids a bulky cooler and is convenient for installing it on the star scene simulation equipment. Finally in the experiment of calibrating the simulation star magnitudes the ability of its calibration is confirmed to reaches up to 12m
meanwhile its calibration error is within 0.2m. 2009 SPIE.

Current research on infrared simulation often focuses mainly on infrared imaging simulation by computer and pays little attention to outdoor simulation of infrared radiation characteristics of targets. In order to simulate infrared radiance of targets outdoors
in this paper we propose a new outdoor simulation method on the basis of heating the cloth by electricity. There are two major contributions in the paper. Firstly
uneven distributing of temperature field of the cloth surface is considered and the long-wave thermal imager is used as a link of the temperature control system. On the basis of many experiments
the expression is concluded about the relation of the temperature obtained by the lone-wave thermal imager and the temperature obtained by the temperature control system and the environmental temperature at the experimental scene. Secondly
the influence of the environment at the experimental scene on the infrared radiance of the cloth surface is thought over. Thanks to two measures above
simulation precision of infrared radiance is made much better. The results of many outdoor experiments demonstrate the performance of the proposed approach. 2009 SPIE.
