Problems solved by technology

[0007] In summary, the existing semantic segmentation methods based on RGBD images are mostly the characteristics of simple stacked convolutional network in the data fusion of color images and depth images. This method often cannot integrate the features of color images and depth images well. , nor has the ability to learn the global context information of the image

Abstract

The invention provides an RGBD image semantic segmentation method. The method comprises the following steps of: S1, acquiring data of a training sample; S2, constructing a configurable depth model and inputting data of the training sample into the depth model to train the depth model; S3, obtaining a color image needing semantic segmentation and a corresponding depth image, analyzing the color image and the depth image by utilizing the trained depth model, and predicting an object to which each pixel in an RGBD image belongs; and S4, forming and outputting a predicted image semantic segmentation image according to a result obtained in S3. According to the method, a deep-level convolutional neural network, a long / short-time memory network and big data are utilized, so that features of color images and depth images can be effectively fused, context information in the images can be effectively mined, and high correctness is provided.

Description

technical field [0001] The invention relates to the fields of computer vision and pattern recognition, in particular to a method for semantic segmentation of RGBD images based on a convolutional neural network and a long-short-term memory network. Background technique [0002] Semantic segmentation is an important field in computer vision research. Its main task is to enable computers to know "what" each pixel in an image is. Its applications include robot task planning, pose estimation, and content-based image retrieval. The goal of semantic segmentation is to hope that the computer can automatically predict the object category of each pixel in an unknown image, such as tables, roads, walls, etc. Semantic segmentation can be divided into two directions: semantic segmentation based on outdoor scene images and semantic segmentation based on indoor scene images. In recent years, cheap depth sensors, such as kinect, realsence, xtion, etc., have provided an additional data sour...
