Abstract

The invention discloses a visual position recognition method, a visual position recognition device, computer equipment and a nonvolatile computer readable storage medium. The visual position identification method comprises the following steps: constructing an auto-encoder model, wherein the auto-encoder model comprises an encoder model and a decoder model which are connected in sequence; inputtingthe training image into a pre-trained VGG-16 model to output first information of the training image; inputting the training image into the auto-encoder model to output second information of the training image; calculating a difference value between the first information and the second information; when the difference value is smaller than a preset value, determining that training of the auto-encoder model is completed; when the difference value is greater than a preset value, modifying parameters of the auto-encoder model, and returning to the step of inputting the training image into the auto-encoder model to output second information of the training image; and carrying out visual position identification by utilizing an encoder model in the trained auto-encoder model.

Description

technical field [0001] The present application relates to the technical field of machine vision, and in particular to a visual position recognition method, a visual position recognition device, computer equipment, and a non-volatile computer-readable storage medium. Background technique [0002] Visual position recognition has important application value in many fields, for example, it can be used for closed-loop detection of SLAM system, and it can also be used for image search based on visual content, 3D modeling and vehicle navigation. Visual location recognition faces many challenges, such as climate, environmental changes caused by lighting, dynamic object occlusion, different angles of content captured by cameras, and real-time performance of the system, all of which will affect the accuracy of visual location recognition. [0003] Currently, visual location recognition can be performed through deep learning-based visual localization methods. However, there are some p...
