At present
micrometer is used for measure the shape edge of automobile airbag. There are some shortcomings in this method. The number of test points is limited. Test data is not comprehensive. Detection speed is slow and a fixture can only test a kind of airbag. The method of airbag shape edge detection based on image processing is researched in this paper. The image of airbag is collected by CCD
and then it is sent to the computer to be processed and segmented. The edge of image is extracted through Canny edge detection algorithm in order to acquire shape edge of airbag in this paper
and the image similarity degree are calculated to provide the information of matching in the template matching process. Finally the comprehensive test shape edge of airbag is realized. The experimental results show that the detection method is effective feasible
intuitive and clear. 2012 IEEE.

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.

In order to achieve the dynamical detection and real-time analysis of the movement status of the magnetic fluid
according to the difficulties of the detection of the magnetic fluid
established a high-speed acquisition and processing system of laser speckle signal on the magnetic fluid. First of all
the FPGA (EP2C8T144C8N) drived the linear array CCD(TCD1501D) to scan in the corresponding time sequence given by the computer
collected the laser speckle interferometric image in rapid change on the surface of the magnetic fluid
which followed the movement of the magnetic fluid
and the signal collected by CCD was converted into the digital data through the high-speed A/D convertor and stored into the internal buffer FIFO of the FPGA
whose width and depth were designed by the user as required. Then
the FPGA sent the digital signal of the laser speckle interferometric images into the computer through the USB2.0 highspeed differential bus
whose transmission rate can reach 480Mb/s in theory. Finally
the distribution of the laser speckle on the magnetic fluid was messy and random
which carried certain information about the surface of the magnetic fluid
based on the theories of the statistic correlation and the subdivision of images
analysing and processing the laser speckle interferometric images
indirectly got the movement status of the magnetic fluid under the electromagnetic field. The experimental results show that: the High Speed Acquisition and Processing System has the advantage of full-court
non-contact
non-invasive
high-precision and high reliability and so on. The detection resolution of high speed acquisition and processing system is superior to 1m and the sample rate is 3Msps
which basically meets the requirements of the magnetic fluid movement state detection. 2009 SPIE.

Many of the video image trackers today use the centroid as the tracking point. In engineering
we can get several key pairs of peaks which can include the target and the background around it and use the method of Otsu to get intensity thresholds from them. According to the thresholds
it give a great help for us to get a glancing size
a target's centroid is computed from a binary image to reduce the processing time. Hence thresholding of gray level image to binary image is a decisive step in centroid tracking. How to choose the feat thresholds in clutter is still an intractability problem unsolved today. This paper introduces a high-accuracy real-time automatic thresholding method for centroid tracker. It works well for variety types of target tracking in clutter. The core of this method is to get the entire information contained in the histogram
we can gain the binary image and get the centroid from it. To track the target
so that we can compare the size of the object in the current frame with the former. If the change is little
such as the number of the peaks
the paper also suggests subjoining an eyeshot-window
we consider the object has been tracked well. Otherwise
their height
just like our eyes focus on a target
if the change is bigger than usual
position and other properties in the histogram. Combine with this histogram analysis
we will not miss it unless it is out of our eyeshot
we should analyze the inflection in the histogram to find out what happened to the object. In general
the impression will help us to extract the target in clutter and track it and we will wait its emergence since it has been covered. To obtain the impression
what we have to do is turning the analysis into codes for the tracker to determine a feat threshold. The paper will show the steps in detail. The paper also discusses the hardware architecture which can meet the speed requirement.

Optical interconnection is the key technique of high-speed optical information process and optical communication. A lot of approaches for optical interconnection have been proposed since Goodman in Stanford University firstly proposed the optical interconnection for very large scale integrated circuits technology. A dynamical addressing device for optical interconnection was designed and fabricated in this paper. This optical device is based on one-dimensional nonlinear photonic crystal made on the planar waveguide. The nonlinear materials ZnS and ZnSe
which have large nonlinear refractive index coefficients
were alternately deposited on the waveguide to form one-dimensional photonic crystal. The Bragg condition is changed when the input power of the control light increased due to the nonlinear characters of the materials
thus the reflective angle of the signal light can be changed with the input power change of the control light. In our experiment
when increasing the power density of control light from 0 to 2.60X105W/cm 2
the angle of the signal beam can be changed about 20. The interconnection characteristics were investigated in theory and in experiment. The testing data agree well with theoretical predictions. This kind of devices is promising to use in the all-optical interconnection
optical information processing and optical communication.
