Optionally, the device further includes: a light filling unit, configured to provide supplementary light on the object while the line scan camera is controlled to perform image capturing on the object.
Optionally, the device further includes: a first detecting unit, configured to detect incoming of the object, generate an incoming signal in response to that the incoming of the object is detected, and transmit the incoming signal to the speed measuring unit to trigger the speed measuring unit to measure the speed of the object.
Optionally, the device further includes: a second detecting unit, configured to detect leaving of the object; generate an outgoing signal in response to that the leaving of the object is detected, to trigger the control unit to control the line scan camera to stop the image capturing on the object.
Optionally, the object is a vehicle; and
wherein the control unit is further configured to control the line scan camera to perform image capturing on a chassis of the vehicle with the line frequency.
In order to achieve the above objective, an embodiment of the present application further provides a system for acquiring an image of a chassis of a vehicle, including a speed measuring module, a control module and a line scan camera; wherein
the speed measuring module and the line scan camera are electrically connected to the control module, respectively;
the speed measuring module is configured to measure a speed of the vehicle and transmit the measured speed of the vehicle to the control module; and
