Problems solved by technology

[0002] In the computer vision neighborhood, the recognition of multi-target objects has always been a huge challenge. Most of the traditional computer vision technologies use the method of traversing the entire image to recognize objects, which greatly limits the recognition speed of target objects.

Embodiment Construction

[0012] Embodiments of the present invention will be described in detail below.

[0013] A scene perception method, the method comprising the steps of: A, obtaining a common image of the scene by a common camera, and obtaining a distance image of the scene by a depth camera; A0, sampling the common image and the distance image to a constant size; A1, the depth camera and There is a camera distance between ordinary cameras, and the distance image and ordinary image are registered through the camera distance; B. Map the points in the distance image to the corresponding positions in the ordinary image; C. Segment the elements in the ordinary image through the distance image It is a plurality of sub-images; D, each sub-image after segmentation is identified through a filter. If the sub-image is a non-target image, there is also a step E after the D step: the elements in the ordinary image are re-segmented into multiple sub-images according to different distances in the distance ima...

Abstract

The invention discloses a scene perception method, comprising the following steps of: A, obtaining a common image of a scene via a common camera, and obtaining a distance image of the scene via a depth camera; B, mapping spots in the distance image to corresponding positions in the common image; C, dividing elements in the common image into a plurality of partial images via the distance image; and D, recognizing the divided partial images via a filter. The recognition velocity of the scene perception method of the invention can be improved significantly.

Description

technical field [0001] The invention belongs to the field of image recognition and processing, and in particular relates to a scene perception method. Background technique [0002] In the computer vision neighborhood, the recognition of multi-target objects has always been a huge challenge. Most traditional computer vision techniques use the method of traversing the entire image to recognize objects, which greatly limits the recognition speed of target objects. As a natural visual system, the human eye is superior to all current computer vision systems. In some fields with very high real-time requirements such as security monitoring, how to improve the recognition speed of target objects is undoubtedly of great significance. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a scene perception method, the recognition speed of which can be significantly improved. [0004] Its technical scheme is a...
