Abstract
To effectively reduce traffic accidents caused by night driving and provide initiative whole system for car driving in environment of lower visibility, sub-model of pedestrians at night based on far infrared sensor technology was designed according to basic requirements of driver assistant system of cars in the industry. Original data source was extracted for this model via far infrared sensor and its ROIs were obtained by using grey statistical technology. Matching detection was conducted on data source on basis of constructing multi-scale probability template, and detection rate as well as rate of leak detection of designed models could be effectively improved via comprehensive treatment technology of multi-frame verification. Experiments show that probability template of this model is improved on matching precision compared with common methods in the industry. It is applicable to two kinds of traffic road conditions of suburb and downtown at the same time, so it has good practicability.
