Obstacle detection device
Abstract:
An obstacle detection device is provided, which includes a storage unit, a quasi-vertical edge detection module, an intersection determination module, a position determination module, and an obstacle detection module. The quasi-vertical edge detection module receives an input image and performs a quasi-vertical edge detection procedure on the input image to obtain a plurality of quasi-vertical edges. The intersection determination module determines whether the quasi-vertical edges intersect a predetermined virtual horizontal. If one of the quasi-vertical edges intersects the predetermined virtual horizontal, the position determination module determines whether an end of one of the quasi-vertical edges intersecting the predetermined virtual horizontal is located in a detection zone. If one end of one of the quasi-vertical edges intersecting the predetermined virtual horizontal is located in the detection zone, the obstacle detection module determines that an obstacle exists and issues a warning.
