Abstract: The present disclosure provides a method for table extraction. The method includes: extracting a screen picture corresponding to a screen content of the touch control display device in response to an operation instruction; detecting the screen picture to obtain a second table corresponding to the first table contained in the screen picture; obtaining text information in the screen picture; and establishing a matching relationship between the second table and the text information to obtain the second table containing a text. When a user needs to save the screen content, the user may trigger extraction of the screen picture. Next, the second table corresponding to the first table in the screen picture and text information in the second table may be automatically extracted, and the second table and the text information are saved as a destination document.

Abstract: The present disclosure provides an object tracking method and an object tracking device. The object tracking method is applied to an image capturing system which includes at least two cameras having image capturing areas at least partially overlapped. The object tracking method includes: obtaining images captured by the at least two cameras, respectively; and respectively identifying objects in the images captured by the at least two cameras; obtaining a feature value of each object, and calculating a position of each object in each image in a global coordinate system; when there are two objects, which are respectively in the images captured by the at least two cameras and have an overall difference value being less than a threshold, counting the two objects as an identical object; wherein the overall difference value is a value determined according to a feature difference value and a position difference value of the two objects.
