摘要
针对弹痕数据采集时因人工调节造成的测量误差以及弹头表面损伤等因素造成的随机误差,对弹痕三维数据与图像处理进行研究。应用坐标变换对测量数据进行预处理,通过小波变换原理对其随机性误差进行降噪,得到处理后的数据和图像,并采用弹痕三维图像数据处理前后的对比。结果表明:该方法能有效提高对比可靠性,并且能够同时进行多个弹头对比,提高工作效率。
According to the measurement errors caused by manual adjustment and the random error caused by surface damage of bullet, 3D data and image processing on the bullet mark are researched. Coordinate transformation measurement data preprocessing can be used, through the wavelet transform to reduce the random error, the treatment of data and images can be obtained, and the 3D data of the bullet mark before and after processing are contrasted. The results show the contrast reliability can be increased by this method, multiple bullets can be compared simultaneously, and the working efficiency is improved.
