指纹识别控制系统设计 摘要 指纹识别技术是以数字图像处理技术为基础，而逐步发展起来的。相对于密码、各种证件等传统身份认证技术和诸如语音、虹膜等其它生物认证技术而言，指纹识别是一种更为理想的身份认证技术。使用指纹识别具有许多优点，例如：每个人的指纹都不相同，极难进行复制或被盗用；指纹比较固定，不会随着年龄的增长或健康程度的变化而变化；最重要的在于指纹图像便于获取，易于开发识别系统，具有很高的实用性和可行性。Fingerprint Identification Control System Abstract Fingerprint Identification technology is gradually developing with the digital image processing technology. Comparing with the password or other traditional documents such as identity authentication technology and voice, iris and other biological authentication technology, Fingerprint Identification is a better identity authentication technology. There are many advantages using Fingerprint Identification. For example: every person’s fingerprints are not the same that it is very difficult to copy or embezzled; Fingerprint is not change with the increasing age or the health status; The most important is that it is easy to get the fingerprint image and make a identification system, it is of high relevance and feasibility. It is possible to compare two fingerprints with the electronic integrated manufacturing technology creating a small image of the fingerprint reading equipment and the great development of the personal computer provides a faster computer or even in a MCU. The fingerprint identification algorithm is very mature, it is able to be used in a variety of security detection devices, and to control many kinds of things. Now the Fingerprint Identification technology has been used in attendance, access control, insurance, and other realm. I believe it will be widely used in the ID card, automobile, home and other realm with the improvement of fingerprint identification technology. The design uses LTT-C500 fingerprint sensor and ARM7 to build the fingerprint identification module, and does the fingerprint identification algorithms then sends the result using the serial port. Control part mainly uses the AT89S52 to complete communications with the fingerprint identification module and PC, and control external ci
