Vehicle Video Data Analysis And Research On Distance Measuring Method

Visual ranging is a field of computer vision that studies biological vision.Similar to the process of obtaining external information from the biological vision system,the method of vision location first requires the aid of photographing instruments to obtain two-dimensional images that record external information,and then uses a computer to study the relationship between the two-dimensional image and the external information.Finally,a series of operations are carried out to get the distance of external objects.The visual ranging method only needs camera equipment during the ranging process.This method realizes low cost,and the method does not send any information to the outside world,it does not cause environmental pollution in any sense.Because of the superiority of the vision ranging method,advanced products have been developed in various fields by visual ranging.However,almost all of these products use the traditional lateral binocular vision ranging method,this can not help triggering a series of thinking.Binocular vision range finding method must use the lateral model?Can only use one camera to complete binocular vision ranging?With these thoughts,the main research work in this paper is as follows:1.Researching a method of vertical binocular vision ranging method.This paper studies the traditional lateral binocular vision ranging model and its mathematical principles,a vertical binocular vision location model is proposed,the concrete method of longitudinal distance measurement is given,the experiment of distance measurement is carried out.The experimental results show that the measurement accuracy of the longitudinal binocular vision ranging method is almost the same as that of the traditional lateral binocular vision ranging method.This represents the application using the lateral binocular vision ranging method can also use the longitudinal binocular vision method.2.Combined video using monocular simulation for vertical binocular distance measurement.With the application of street light location based on vehicle video as an example,this paper discusses how to use only one camera to complete binocular vision ranging.This is because the relationship between the front and rear frames in vehicle video represents the front and rear pictures in the longitudinal binocular vision ranging method.Experimental results show that monocular simulate binocular range can be used.
