Abstract

The invention discloses a title photographing and searching method and system. The method comprises the following steps: photographing a title to obtain a picture; calculating the angle between the title placing plane and the camera lens plane; determining that the angle is greater than or equal to the preset threshold value, and conducting deflection correction on the picture; conducting title searching by utilizing the picture subjected to deflection correction. When the title is photographed, whether the photographing angle is reasonable or not is detected by calculation of the angle between the title placing plane and the camera lens plane, when the angle is greater than the preset threshold value, deflection correction is conducted on the picture, and the picture subjected to deflection correction is utilized to conduct title searching, so that the picture recognition efficiency can be improved, and the title searching accuracy can also be improved.

Description

technical field

[0001] The invention relates to the field of intelligent question search, in particular to a method and system for searching questions by taking photos. Background technique

[0002] At present, there are many question-searching software on the market. The process of taking pictures and searching questions is relatively simple. You just use the camera to take pictures, and then use the photos to search questions. If the angle of the photo is taken is large, the question information in the photo is not easy. If it is recognized, the accuracy of the search question is not high. Contents of the invention

[0003] The purpose of the present invention is to provide a method and system for searching questions by taking pictures. The purpose of the present invention is to solve the problems that the pictures are not easy to be recognized and the accuracy of searching questions is not high due to poor photographing angles.

[0004] For reaching this purpose, the p...
