Abstract

The invention provides an obstacle detection alarm system and method. An interest interval is set through an image processing technology to further judge whether a horizontal line signal exists, and the obstacle of certain height is detected according to the detection of obstacle profile and estimation of the distance between obstacles at a ground interval; if the system detects that the obstacleexists, the system can provide an timely alarm and display the obstacle distance through an alarm device; and an environment picture can be displayed by use of an image type obstacle detection alarm system in combination of the alarm device so that a driver can directly and clearly see the relative position relationship of the environment and the convenience and safety are enhanced.

Description

technical field [0001] The present invention relates to an obstacle detection and warning system and method, in particular to an obstacle detection warning system and method using image technology. Background technique [0002] For most domestic drivers, it is not easy to drive on the busy urban roads, and it is even more confusing to put the car into the narrow parking space on the crowded street. Improper driving will cause the vehicle to directly collide with obstacles or cause unfortunate accidents because there is no good warning system that can warn the driver in a timely manner. [0003] Fortunately, with the progress of the automobile industry, many inventions related to Parking Guidance System (PGS) and Parking Assistance System (Parking Assistance System, PAS) have been produced accordingly, but in the past, most of the general parking guidance systems used such as Radar and ultrasonic sensing components will reduce the recognition rate due to the inability to rec...
