摘要

某管状药柱塑性较大

在生产过程中

由于挤压等原因

端面不是规则的圆环形

其平均内外径尺寸直接关系到弹药的性能。目前的内外径尺寸检测技术只能检测单个目标

检测平均内外径需要拍摄多幅图像

取这多幅图像目标尺寸平均值。为此

提出了利用面阵电荷耦合器件（面阵CCD）摄像机获取目标图像

每幅图像可包含多个目标

然后

采用二维傅里叶描述子对不同目标进行识别

根据药柱是否相同判断其是否离开视场

实现了对多个药柱尺寸同时检测

极大地提高了检测速度

采用多项式插值技术进行亚像素边缘检测

使测量精度高于0.01mm

达到微米级。

Abstract

Some tubular cartridge has bigger plasticity.On cartridge production

because of extrusion

the case is not a regular circle ring.The cartridge case’s average inner and outer diameters are directly related to the ammunition’s performance

The current inner and outer diameter measuring technology can only measure single object to measure average diameters

it needs to get many images of the object to attain the average of the images. The method is proposed to attain cartridge images with area charge coupled device（CCD）camera

every image contains many objects.Two dimensional Fourier descriptor is used to recognize difference objects

according to cartridges being or not the same cartridge

to judge whether the cartridge is in the field.With the technology

many cartridges can be measured in the same time

extremely improved the measurement speed.The method adopts polynomial interpolation to realize sub-pixel edge detection.The precision is higher than 0.01 mm

reaches macron level.
