Problems solved by technology

[0004] Existing visual relocalization techniques mostly use traditional local features, such as scale-invariant feature transform (SIFT). However, when the light difference between the offline map and the real running scene is large, traditional local features are used Feature matching and searching for features are easy to introduce wrong feature matches, or the number of correct matches is small, thereby reducing the accuracy of relocation

Abstract

The invention provides a data processing method and device. A place database is pre-constructed by adopting a deep neural network; all features and local features of a key frame image in the locationdatabase are obtained by deep learning of a deep neural network. In the deep neural network learning, it is assumed that the descriptor of the local feature of the key frame image has a certain degreeof light variability, so that when the light change is large, the key frame image can be accurately matched in the place database despite the large change of the descriptor of the local feature of the first image.

Description

technical field [0001] The invention relates to the technical field of neural networks, in particular to a data processing method and device. Background technique [0002] For small intelligent robots, visual relocation technology plays an important role. Relocation refers to: when the robot's positioning fails, the robot compares the three-dimensional map of the operating environment established offline to retrieve the current robot's position and posture. , so as to ensure the normal operation of the robot. [0003] Usually, the cause of robot positioning failure is generally caused by human or environmental interference factors during actual operation. For example: the camera of the robot is temporarily blocked by people, resulting in no effective visual information, the robot is abducted or forced to move its position, and the robot passes through places with strong changes in indoor and outdoor light, etc. After the interference factors are removed, the robot needs to...
