Abstract

The invention relates to a camera mobile terminal having a scene identification function. The camera mobile terminal comprises a camera mobile terminal body and a scene identification device installed on the camera mobile terminal body. The scene identification device consists of an image preprocessing module, an image extreme point detection module, an image feature point positioning module, a main direction determination module, a feature extraction module and a scene determination module. The image feature point positioning module rejects a low-contrast-ratio point sensitive to noises and instable edge point in all extreme points to determine an extreme point as a feature point; the main direction determination module is used for enabling any two adjacent peak values in a gradient direction histogram associated with the feature point to be connected in a line to form a plurality of sub line segments, combining the adjacent sub line segments having approximate slopes at a length direction, and using the direction of the optimal line segment among the multiple line segments as a main direction of the feature point after formation of one line segment. The camera mobile terminal has advantages of high scene identification precision and fast speed.

Description

technical field [0001] The invention relates to the field of photography, in particular to a camera mobile terminal with a scene recognition function. Background technique [0002] Ordinary cameras can only acquire images. If the camera mobile terminal can judge the scene, and then realize the automatic classification of image data, the efficiency will undoubtedly be greatly improved, thereby reducing the workload of humans. However, the current camera mobile terminal does not have a scene determination function. In addition, in order to process a large amount of image data, it is necessary to improve analysis processing efficiency and accuracy. Contents of the invention [0003] In view of the above problems, the present invention provides a camera mobile terminal with a scene recognition function. [0004] The object of the present invention adopts following technical scheme to realize: [0005] Provided is a camera mobile terminal with a scene recognition function, w...
