The present disclosure provides a method and apparatus for processing an image, and relates to the field of artificial intelligence, and particularly to the field of intelligent transportation. A specific implementation includes: acquiring a top view of a road; identifying a position of a lane line from the top view; cutting the top view into at least two areas, and determining, according to the position of the lane line in each area, a width of a lane in the each area and an average width of the lane in the top view; calculating a first perspective correction matrix by optimizing a first loss function, the first loss function being used to represent a difference between the width of the lane in the each area and the average width of the lane in the top view; and performing a lateral correction on the top view through the first perspective correction matrix to obtain a first corrected image. According to the implementation, the deformation of the top view is calibrated, thereby greatly improving the precision of positioning an element in the top view.
