The present invention relates to a method and to an apparatus for generating a surrounding image. The method for generating a surrounding image according to the present invention comprises the steps of: taking, as an input, images captured by cameras installed in the front and the rear of a vehicle and in the left and right sides of the vehicle, via respective channels connected to the cameras; correcting the captured images into a top view form to generate a plurality of corrected images; performing an overlaying process on the plurality of corrected images using a mask image containing region information on each channel and weight information for pixels constituting each region to generate a surrounding image of the vehicle; and displaying the thus-generated surrounding image. The present invention removes blind spots around the vehicle, and corrects the overlapped images captured by a plurality of cameras into natural images, thus enabling drivers to accurately recognize the surrounding situation of the vehicle. Therefore, a driver may park a vehicle in a convenient manner, and drive the vehicle in a forward or a backward direction in a safe manner even without looking at a side-view mirror or a rearview mirror.
