Abstract

The invention relates to the field of automatic navigation of computer visual devices, in particular to an anti-deviation alarm device for an automobile. The device comprises a pinhole camera, a video coder, a digital signal processor, a video decoder, a display screen, an audio decoder and a loudspeaker, wherein the pinhole camera is arranged in the front centre of the automobile top and captures the front pavement image of the automobile; the video coder converts the analogue signal of the pavement image into a digital signal and stores the digital signal; the digital signal processor processes the pavement image in the digital signal format and outputs the current pavement information of the automobile and the deviation alarm information; the video decoder receives current pavement information of the automobile and converts the current pavement information into an analogue signal; the display screen receives the analogue signal of the current pavement information of the automobile and outputs the pavement image; the audio decoder receives the alarm information and converts the alarm information into an analogue signal; and the loudspeaker receives the analogue signal of the alarm information and outputs an alarm signal.

Description

technical field [0001] The invention relates to the field of autonomous navigation based on a computer vision device, in particular to an anti-deviation alarm device for automobiles. technical background [0002] As mankind enters the 21st century, computer technology and the automobile industry have developed rapidly, and many intelligent controls have been widely used in modern automobiles. The use of intelligent controls on modern cars has greatly improved the safety of the car. [0003] However, from the analysis of human visual theory, intelligent control can achieve real-time effects only when the processing speed of the image processing device reaches more than 25 frames per second. In order to ensure the real-time performance of the image. However, the biggest difficulty in existing technologies is how to solve the real-time problem of image processing, that is, how to complete the processing of a large amount of image data within a limited time.
