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

Target detection and tracking technology in infrared image is an important part of modern military defense system. Infrared dim-point targets detection and recognition under complex background is a difficulty and important strategic value and challenging research topic. The main objects that carrier-borne infrared vigilance system detected are sea-skimming aircrafts and missiles. Due to the characteristics of wide field of view of vigilance system
the target is usually under the sea clutter. Detection and recognition of the target will be taken great difficulties.There are some traditional point target detection algorithms
such as adaptive background prediction detecting method. When background has dispersion-decreasing structure
the traditional target detection algorithms would be more useful. But when the background has large gray gradient
such as sea-sky-line
sea waves etc.The bigger false-alarm rate will be taken in these local area.It could not obtain satisfactory results. Because dim-point target itself does not have obvious geometry or texture feature
in our opinion
from the perspective of mathematics
the detection of dim-point targets in image is about singular function analysis.And from the perspective image processing analysis
the judgment of isolated singularity in the image is key problem. The foregoing points for dim-point targets detection
its essence is a separation of target and background of different singularity characteristics.The image from infrared sensor usually accompanied by different kinds of noise. These external noises could be caused by the complicated background or from the sensor itself. The noise might affect target detection and tracking. Therefore
the purpose of the image preprocessing is to reduce the effects from noise
also to raise the SNR of image
and to increase the contrast of target and background. According to the low sea-skimming infrared flying small target characteristics
the median filter is used to eliminate noise
improve signal-to-noise ratio
then the multi-point multi-storey vertical Sobel algorithm will be used to detect the sea-sky-line
so that we can segment sea and sky in the image. Finally using centroid tracking method to capture and trace target. This method has been successfully used to trace target under the sea-sky complex background. 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).

A key problem of attitude measurement of small-multi-target with high speed is how to decide the optimum of the CMOS stations. A multi-CMOS station mode is designed in this paper
multiple CMOS videos were placed on two parallel sides in measurement system
every two CMOS form an intersection viewing field
multiple viewing field join to cover shooting range
which can augment Effective Viewing Field(EVF)
increase capture ratio of objects with high speed and measurement precision of small objects. When an object passes through the joint area
it will be imaged separately on each CMOS focal plane. Multiple CMOS videos were triggered synchronously
a sequence of image information was extracted
the target attitude was confirmed by digital image processing technology. The merit of station mode is low cost
large measurement scope
extending freely and so on. 2010 IEEE.

A key problem of attitude determination system is how to locate CMOS cameras and deal with relations among them. In this paper
several kinds of multi-CMOS station mode are introduced. Fundamental principles and classification of station mode directly affect on measurement parameters of system. No matter what mode is designed
the ultimate goal is to extend Effective Viewing Field (EVF)
increase capture ratio of objects and increase measurement precision. Station mode introduced in this paper is made of CMOS cameras
because of low cost
high speed frame frequency and low power consumption
CMOS cameras were putted near from object tested. So sequences of image are legible
which are convenient for analysis of three dimensional(3D) attitude. 2010 IEEE.
