The remarkable improvement of sensing and processing hardware performance makes the non-contact
on-line
high accuracy and high speed measuring possible by means of linear CCD. The goal of this pager is to describe the key questions on designing the cone diameter detecting system by linear CCD. This paper first describes the detecting scheme. In particular
the factors affecting accuracy
such as resolution
voltage difference between neighbor pixels
detecting rate and so on
are analyzed
and the quantitative estimation equations are provided. CCD takes on the photoelectric translation and measuring component double functions
so the waveform of CCD output signal and the affecting factors merit deep discussion. On the basis of discussion
several principles that can be used to improve the boundary recognition accuracy are presented.

In this paper
the time of feature extraction is faster. By test in low contrast image
2D continues Gabor wavelets are adopted to realize feature extraction. By optimize Gabor wavelet's parameters of translation
the feasibility and effectiveness of the algorithm are demonstrated by VC++ simulation platform in experiments. 2004 IEEE.
orientation
and scale to make it approximates a local image contour region. The method of Sobel edge detection is used to get the initial position and orientation value of optimization in order to improve the convergence speed. In the wavelet characteristic space
we adopt PSO (particle swarm optimization) Algorithm to identify points on the security border of the system. Comparing to the LM algorithm
it can ensure reliable convergence the target
which can improve convergent speed
