The determining unit is configured to determine line frequency for image capturing according to the speed of the object.
The control unit is configured to control a line scan camera to perform image capturing on the object with the determined line frequency.
Optionally, the speed measuring unit is further configured to capture images of the object in motion continuously by using an image capturing module, and to calculate the number of pixels VP that the object travels across per unit time on an imaging plane of the image capturing module by using the continuously captured images.
The determining unit is further configured to determine the line frequency for image capturing according to the calculated number of pixels Vp.
Optionally, the speed measuring unit can be specifically configured to:
determine relative positions of a feature point of the object both in the i-th image and in the (i+1)-th image captured by the image capturing module, wherein i is an integer and 1≤i<m, and m is the total number of the images captured by the image capturing module;
determine the number of pixels n between the determined two relative positions; and
determine the number of pixels Vp that the object travels across per unit time on the imaging plane of the image capturing module according to the following formula: Vp=n/t;
wherein t is a time interval between the capturing of the i-th image and the capturing of the (i+1)-th image by the image capturing module.
Optionally, the determining unit can be specifically used to:
