Definitions
- the invention belongs to the field of automobiles and provides a method for limiting the speed according to a fingerprint and a speed limiting system.
- Fingerprint recognition refers to the identification by comparing the detailed feature points of different fingerprints. Fingerprint recognition technology involves image processing, pattern recognition, Computer vision, mathematical morphology , wavelet analysis and many other disciplines. Since each person's fingerprint is different, there is a clear difference between the fingers of the same person, so the fingerprint can be used for identification. Because the orientation of each print is not exactly the same, different points of force will bring different degrees of deformation, and there are a lot of fuzzy fingerprints. How to correctly extract features and achieve correct matching is the key to fingerprint recognition technology.
- Speeding mainly has the following hazards: First, speeding, vision loss, and judgment is not allowed.
- the driver's vision in driving is called dynamic vision.
- the dynamic vision In general, the dynamic vision is lower than the static vision. 10% to 20%.
- Dynamic vision is inversely proportional to speed. The faster the speed, the more vision loss. At a speed of 60 km, the viewing distance was 240 m, and at 80 km, the viewing distance was reduced to 160.

Description
本发明属于汽车领域，提供了一种根据指纹限制极速的方法以及限速系统。
指纹识别即指通过比较不同指纹的细节特征点来进行鉴别。指纹识别技术涉及 图像处理 、 模式识别 、
计算机视觉 、 数学形态学
、小波分析等众多学科。由于每个人的指纹不同，就是同一人的十指之间，指纹也有明显区别，因此指纹可用于身份鉴定。由于每次捺印的方位不完全一样，着力点不同会带来不同程度的变形，又存在大量模糊指纹，如何正确提取特征和实现正确匹配，是指纹识别技术的关键。
每个人的驾驶习惯是不一样的，有人开车遵守交规，该快时快改慢时慢，但是有一些人开车很莽撞，无视交规，喜欢横冲直撞，经常超速，
超速行驶对行车安全为什么构成这么大的威胁？超速行驶主要有以下危害：一是超速行驶，视力下降，判断不准。驾驶人在行车中的视力称为动视力。一般来说，动视力比静视力低
10% 至 20% 。动视力与速度成反比，车速越快，视力下降越多。当时速为 60 公里时，视认距离为 240 米，而 80 公里时，视认距离减少到 160
米；车速越快，视野越窄，这就是所谓的'隧道型视野'。当时速为 40 公里时，视野为 100 度，时速为 100 公里时，视野仅为 40
度，这时两边的景物无法看清；二是超速行驶，反应距离延长。当时速为 60 公里时，人的反应距离为 16.7 米，当时速达 100 公里时，反应距离为 27.8
米。车速越快，反应距离越长，危险越大；三是超速行驶，制动距离延长。不同的路面，摩擦系数不同，车速越快，制动距离越长，发生事故的可能性陡增；四是超速行驶，干扰正常车流。超速行驶的车辆必然时刻处于超越正常行驶车辆的状态，每次超车无论是变道还是驶回原车道，都会形成交织点，而每个交织点就是一个交通事故隐患；五是超速行驶，加重事故后果。车速越快，动能越大，冲击力越大，发生事故碰撞时后果越严重。数据显示，当汽车时速
20 公里，把人撞死的几率为 10% ， 40 公里时超过 30% ， 60 公里时超过 90% ， 80 公里以上时则达到 100%
。由此可见，超速行驶是危险可怕的，'超速行驶'历来是公安交管部门整治的重点交通违法行为。
虽然现在的道路限速系统应用的范围已经很广泛了，交通部门对超速者的处罚力度也在不断增加，但还是有有很多驾驶者无视限速提示，在高速路上超速行驶，给他人和自身的行车带来了非常大的危害。
综上，需要针对不同的人驾驶车辆安全性不一样的情况，提供一种通过预设指纹与车辆极速的匹配关系，根据不同用户调整车辆极速，使车辆能根据不同的驾驶者，调整车速，增加行车的安全性，使车辆安全性控制更加智能化。
