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

Comparing with the writing method of plane pattern
spherical pattern' has some remarkable different on several points. Firstly
it is difficult to spin-coated a uniform photoresist film on a spherical substrate
especially the ratio of spherical radius to caliber is smaller
and the spin-coated way must match the ratio of spherical radius to caliber. Secondly
if the sphere couldn't be regarded as a plane
a so-called concentric optical scan movement way must be applied for the generation of spherical pattern
because the reflex of substrate will affect the quantity of illumination. Commonly
an alignment technique is indispensable with pattern generation of spherical surface by the concentric optical scan in order to ensure the orthogonal intersection of focusing laser beam and writing surface. Thirdly
a uniform velocity control must be considered for the laser direct writing method on a spherical substrate. Otherwise
the exposure time of photoresist will be different
and the line widths of pattern will be also different at different areas. Fourthly
commonly
because the errors of concentric machine and substrate surface shape are bigger
so focusing servo-control technique is also needful for writing a pattern on a spherical substrate. Focusing servo-control may keep the focal spot on the spherical surface by a focus detection and control system in the course of writing pattern. Using these techniques
we fabricated a line width of 7m and a period of 600m isometric mesh on the concave of a spherical substrate.

This paper describes a kind of automatic test technology of the parameters used in a dual-CCD TV measure-system (TV -MS) .The TV -MS is the ground control equipment of the anti-tank missile and integrates the technologies of optical
machine and electronics. It is important and key component. The main technical parameters of the TV -MS are field of view
zero point
precision
sensitivity
anti-jamming ability
zooming time and focus time
etc. To insure the TV -MS satisfying the tactical and technical requirements and discover fault and reason
a fast and accurate equipment satisfying the test technical parameters of the TV -MS is urgently needed in manufacture and service. Firstly
the parameter test system converted optical signal to electronic signal
implemented automatic control of the invariant illumination of parallel pipeline output. Secondly
data and command delivering
displaying or printing are realized by using 80C196KB. The experiment result shows that the approach of automatic testing of the Parameters used in a dual-CCD TV -MS is successful and it can be used for all tests of the functions and parameters of the TV -MS. The main innovations are to realize the fast
veracious measure of technical parameters of the dual-CCD TV-MS
and integrate the technologies of optics
machineries and electronics. An advanced means is provided to judge the technical states
find malfunctions and discover the reasons in producing and maintaining process. The equipment suited for anti-tank missile systems is given.
