step S530, determining the matching result of each similar template page and the presentation to be converted according to the first matching value and the second matching value;

and step S540, determining a target page from each similar template page according to the matching result of each similar template page and the presentation to be converted.

It can be understood that, merging the presentation to be converted and each of the similar template pages means that the content of the presentation to be converted is completely copied to each of the similar template pages to obtain a corresponding merged page, in the merged page, the first text position information and the second text position information are analyzed to obtain a first matching value for representing the text matching degree through calculation, and the first picture position information and the second picture position information are analyzed to obtain a second matching value for representing the picture matching degree through calculation; and then adding the first matching value and the second matching value to obtain a total matching value, namely a matching result corresponding to each similar template page, selecting the similar template page with the highest total matching value as a target page, effectively screening the similar template page closest to the characteristic information of the presentation to be converted, avoiding the content of the presentation to be converted from being greatly changed in the conversion process, increasing the readability of the target presentation and improving the conversion quality of the presentation.

In specific practice, a first text coordinate of a text box center where a text is located in a page of a presentation is determined through first text position information, a second text coordinate of the text box center where the text is located in the page of the presentation is determined through second text position information, then a first Euclidean distance between the first text coordinate and the second text coordinate is calculated, and a first matching value is further determined, wherein the first matching value and the first Euclidean distance are in a negative correlation relationship, and the smaller the value of the first Euclidean distance is, the larger the first matching value is represented; and determining a first picture coordinate of the picture center in a page of the presentation according to the first picture position information, determining a second picture coordinate of the picture center in the page of the presentation according to the second picture position information, calculating a second Euclidean distance between the first picture coordinate and the second picture coordinate, and further determining a second matching value, wherein the second matching value and the second Euclidean distance form a negative correlation relationship, and the smaller the value of the second Euclidean distance, the larger the second matching value is represented.

It should be noted that the method for calculating the euclidean distance between two coordinates belongs to the techniques well known to those skilled in the art, and will not be described herein.
