Vertical target object i.e. rectangular shaped American signaling panel, detecting method for motor vehicle, involves regrouping detected segments into parallelograms, and detecting target object from parallelograms, using control unit

摘要

The method involves detecting contours in an image acquired by a video camera and detecting horizontal and vertical segments based on size and a slope of the detected contours, using an image processing device. The detected segments are regrouped into parallelograms i.e. rectangles, and a vertical target object i.e. rectangular shaped American signaling panel, is detected from the parallelograms, using a control unit. Independent claims are also included for the following: (1) a vertical target object detecting device comprising an image processing device (2) a computer program product comprising instructions to perform a method for detecting a vertical target object.
