| This paper is in the background of using hemisphere panoramic imaging into auto safety,take the intelligent driving safe.system based on panoramic girdle imaging,which belongs to the State Key Laboratory of Modern Optics and Instrument in Zhejiang University,as the experimental system.This paper,which adopt the stimulation of road enviroment,mainly studied the edge detection of panoramic image and the road mark-line extraction based on panoramic image,and studied the road identify technology based on complex background gray image.This paper presents a approximation algorithm to detect actual direct lane on the panoramic image,and it has been proved by theory analysis and experimental research that the method above is reasonable and reliable.This provides a effictive research method of using panoramic imaging on the auto safetyThis paper discussed the efforts and results that people paid out and gained in expending single optical lens,and analyzed the principles and specific implementations of panoramic cameras of different design schemes.What's more, this paper aummarized the research survey of panoramic vision system,and established a FCP cylindrical projection model which is different from the troditional CCP projection model.Lastiy,this paper provide the method of processing panoramic image and the software implementation.The panoramic monitoring camera used in 360 degree imaging method is different from the common high-speed rotary camera,it captured the scene of 360 degree girdle field in stationary state.All the scene in this area are captured in one image,which truly realized no dead angle,continuous and real-time 360 degree imaging.Panoramic imaging and the machine vision technology based on Panoramic imaging are widely used in scientific research,industry technology,military and business field.Omni-directional camera has a very large view field angle, it has great advantages in scene observation of automatic equipment and information acquisition.However,because of the spatial optical projection mechanism,the image has great perspective distortion.Therefore,the image recovery becomes a problem that must be solved.This paper introduced a binary optical hemisphere panoramic imaging technology based on diffraction/refraction hybrid optical,including geometric model,imaging principle and camera structure,and this paper analyzed the imaging mechanism based on this panoramic vision image.Based on the panoramic imaging principle,this paper presents a important method of processing image and extracting feature on the original panoramic image. And by this way,channel recovery and reconstruction become ture.This paper carry trough the reaserch through two important parameters:declination and the distance departure from the center,it has great achivement in the rationality and feasibility of the algorithm. |
