In current field of CCD measurement
large area and high resolution CCD is used to obtain big measurement image
so that
speed and capacity of CCD requires high performance of later storage and process system. The paper discusses how to use SCSI hard disk to construct storage system and use DSPs and FPGA to realize image compression. As for storage subsystem
Because CCD is divided into multiplex output
SCSI array is used in RAID0 way. The storage system is composed of high speed buffer
DMA controller
control MCU
SCSI protocol controller and SCSI hard disk. As for compression subsystem
according to requirement of communication and monitor system
the output is fixed resolution image and analog PAL signal. The compression means is JPEG2000 standard
in which
9/7 wavelets in lifting format is used. 2 DSPs and FPGA are used to compose parallel compression system. The system is composed of FPGA pre-processing module
DSP compression module
video decoder module
data buffer module and communication module. Firstly
discrete wavelet transform and quantization is realized in FPGA. Secondly
entropy coding and stream adaption is realized in DSPs. Last
analog PAL signal is output by Video decoder. Data buffer is realized in synchronous dual-port RAM and state of subsystem is transfer to controller. Through subjective and objective evaluation
the storage and compression system satisfies the requirement of system. 2009 SPIE.

A novel approach for evaluating the tracking performance of optoelectronic theodolite is proposed. First
an equivalent mathematic model of tracking error is established. Then
the equivalent sine signal is inputted to the equivalent model
and the outputs are sampled. The results of evaluating the tracking performance are obtained based on the statistical calculation of output produced by equivalent model. Equivalent model using the BP (Backprogration) neural network structure is identified. The training method of BP neural network adopts the LM (Levenberg-Marquardt) algorithm for the sake of speeding up training process. The BP neural network is trained and tested by using the training and testing samples gotten from the simulation model of optoelectronic theodolite tracking system under MATLAB/SIMULINK. The estimate errors of equivalent model including average error
maximum error and standard error are 2.5872e-0060
2.8 and 1.9. The results show that the equivalent model identified based on BP neural network meets the needs of evaluating the tracking performance of optoelectronic theodolite. The accurate evaluation of tracking performance is achieved. 2009 SPIE.

In order to measure dynamic interpolation errors of photoelectric encoder of high precision
the dynamic evaluation system of interpolation errors is introduced. Firstly
the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then
the analysis of harmonic wave with the FFT is processed. Compared with the standard signal
the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple
fast
high precision
and can be used in the working field of the encoder. 2009 SPIE.

The first impression of any building to a person is its exterior and decoration
therefore
at the same time
and therefore the quality of decoration project shows the more important position in building project. A lot of projects produce quality problem because of the material color difference
how to grasp and control the color change of building materials
the color difference problem laying stone materials is also studied in this paper
which exists universally at the common project
and carry out color quantification
and the solution scheme has been given using this system.
and is often found at the high-grade decoration
it has the very important meaning. According to the color theory
a computer vision system used in color quantification measurement is established
the standard illuminant A is selected as the light source. In order to realize the standardization of color evaluation
the mutual conversion between RGB and XYZ color space is studied
which is realized by the BP network. According to the colorimetry theory
the computer program is compiled in order to establish the software system
and realize the color quantitative appraisement in whole color gamut. LCH model is used at quantifying the color of building materials
and L*a*V model is used at comparing the color change. If the wooden floor is selected and laid improperly during family fitment
it is easy to present "flower face". The color also arises greater discrepancy using the laths of same tree. We can give the laying scheme using the color quantification system
