說明書
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 a direction from the image capturing module towards the line scan camera.
Optionally, the determining unit is further 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 unit is further 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 further 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;
the determining unit is further configured to: determine new line frequency for image capturing according to the changed speed; and
the control unit is further configured to: continue the image capturing on the object with the newly determined line frequency.
