Lane departure warning system and method of controlling the same

摘要

Disclosed is a lane departure warning system. According to an exemplary embodiment of the present invention, the lane departure warning system includes: an image obtaining unit configured to obtain a travelling image; a region of interest setting unit configured to set a predetermined region of the travelling image as a region of interest; and a controller configured to remove a shadow component included in the region of interest when brightness of the region of interest satisfies a predetermined condition, and detect a line in the region of interest in which the shadow component is removed.

主权项

1. A lane departure warning system mounted in a vehicle, comprising: one or more central processing unit having circuitry configured to:
obtain a travelling image; set a predetermined region of the travelling image as a region of interest; classify each pixel of a plurality of pixels included in the region of interest into a brightness section of a plurality of predetermined brightness sections corresponding to pixel illumination, calculate a number of pixels in the region of interest included in each brightness section, and generate a histogram with the calculated number of pixels for each brightness section; and remove a shadow component included in the region of interest when a ratio of a number of pixels classified into brightness sections having pixel illumination of a predetermined value or smaller to a total number of the plurality of pixels is greater than or equal to a predetermined ratio, and detect a line in the region of interest in which the shadow component is removed.
