Abstract

A dump truck includes a body and a plurality of cameras. The body includes an upper deck and a main frame disposed in a longitudinal direction. The cameras are configured and arranged to obtain images to be combined to generate a bird'"'"'s-eye image to monitor a periphery of the dump truck. The cameras include a front camera, a rear camera and side cameras. The front camera is disposed at the front of the upper deck to obtain an image of an area in front of the body. The rear camera is disposed at a rear end of the main frame to obtain an image of an area in rear of the body. The side cameras are respectively provided on left and right sides of the upper deck to obtain images of an area between diagonally to the front and diagonally to the rear of the body.
