Abstract

The embodiment of the invention provides a loopback detection method and device, a storage medium and a computer program product. The method comprises the steps: obtaining a to-be-detected data frame which at least comprises single-frame point cloud data or point data in single-frame image data; determining a target data frame matched with the to-be-detected data frame within a preset range based on the descriptor of the to-be-detected data frame; determining a transformation matrix between the to-be-detected data frame and the target data frame based on a matching network; and transforming the to-be-detected data frame by using the transformation matrix, and inputting the target data frame and the transformed to-be-detected data frame into a confidence coefficient verification network to obtain a confidence coefficient verification result. The transformation matrix is determined by using a neural network model, confidence coefficient verification is carried out, loopback detection can be realized through a data driving mode, dependence on geometric rules is avoided, the adaptation capability to different scenes is improved, and the accuracy of loopback detection is improved.
