Abstract

The invention discloses an intelligent air purifier. The intelligent air purifier comprises an air purifier and a scene recognition device mounted on the air purifier, wherein the scene recognition device comprises an image preprocessing module, an image extreme point detecting module, an image feature point positioning module, a main direction determining module, a feature extracting module and a scene determining module; the image feature point positioning module is used for determining extreme points of feature points by removing low-contrast points sensitive to noise and unstable edge points among the extreme points; the main direction determining module is used for connecting any two adjacent peak values in a gradient direction histogram about the feature points to form a plurality of sub line segments, merging the adjacent sub line segments with similar slope in a length direction to form a line segment and taking a direction of an optimal line segment among a plurality of line segments as a main direction of the feature points. The intelligent air purifier has the advantages of high scene recognition accuracy and fast scene recognition speed.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an intelligent air purifier. Background technique [0002] The determination of the scene plays an important role for any machine to exert its maximum effect. If the air purifier can determine the scene it is in and select the corresponding mode to purify the air, the efficiency will be greatly improved. However, current air purifiers do not have a scene judgment function. In addition, in order to process large-scale 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 an intelligent air purifier. [0004] The object of the present invention adopts following technical scheme to realize: [0005] Provided is an intelligent air purifier capable of recognizing scenes, including an air purifier and a scene recognition device installed on the air purifier...
