FIG. 4 is a schematic structural diagram of an embodiment of a system for acquiring an image of a chassis of a vehicle mounted with a line scan camera, provided by the present application. Referring to FIG. 4, the system for acquiring an image of a chassis of a vehicle may further include: a metal protection cylinder 141; and the line scan camera 14 is arranged within the metal protection cylinder 141. The line scan camera 14 includes a line scan camera body 142 and a lens 143 that is adapted to the line scan camera body 142.
In the embodiment of the present application, the lens 143 may be selected as a wide-angle lens with an angle rang of 120-180°, depending on the usage. Optionally, the wide-angle lens may be a fisheye lens, which has high definition, good image consistency, uniform brightness, and the field of view covering a range of 180°. The fisheye lens can capture an image including clear images of the bottom of the vehicle and of the side of the wheel.
As shown in FIG. 4, a transparent cover 144 for the lens 143 is arranged on the metal protection cylinder 141. A damage-proof protection member 145 is arranged over the transparent cover 144. A light incident hole 146 is formed in the damage-proof protection member 145. External light enters the line scan camera body 142 through the light incident hole 146, the transparent cover 144, and the lens 143.
