determine the line frequency for image capturing Q according to the following formula when a linking line linking the image capturing module and the line scan camera is parallel to a direction of motion of the object: Q=Vp*(p2/f2)*(f1/p1);
wherein, Vp is the number of pixels that the object travels across per unit time on the imaging plane of the image capturing module; p2 is a size of a single pixel of the image capturing module; f2 is a focal length of the image capturing module; p1 is a size of a single pixel of the line scan camera; and f1 is the focal length of the line scan camera.
Optionally, the direction of motion of the object is the direction from the image capturing module to the line scan camera.
Optionally, the determining unit may be specifically configured to:
determine the line frequency for image capturing according to the speed of the object, the number of pixels per one row of the line scan camera and a preset scale factor.
Optionally, the determining module can be specifically configured to:
calculate the line frequency for image capturing Q according to the following formula: Q=k*w*v;
wherein v is the speed of the object; w is the number of pixels per one row of the line scan camera; and k is the preset scale factor.
Optionally, the speed measuring unit is specifically configured to: detect a change in the speed of the object, and in response to that a change in the speed of the object is detected, determine the changed speed.
