Abstract

The invention provides a positioning reconstruction method and device. The positioning reconstruction method comprises the following steps: acquiring at least two frames of images including a target object; calculating the optical flow of the target object in the at least two frames of images; calculating attitude information of an image acquisition device for acquiring the image according to theoptical flow of the target object; calculating the position information of the target object and the confidence coefficient of the position information according to the optical flow of the target object and the attitude information of the image acquisition device; and establishing a model of the target object in a map based on the position information and the confidence of the position information. According to the positioning reconstruction method, uncertain factors in a position environment can be more effectively dealt with, and the advantages of data fusion are brought into full play, andall information is reserved through the probability density function, and the data is prevented from being discarded, so that the accuracy of positioning and modeling is improved, and the modeling quality is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a positioning reconstruction method and device. Background technique [0002] Even though positioning reconstruction refers to the technology of reconstructing target object models in 3D maps based on collected 2D images, it is widely used in robotics, augmented reality, unmanned driving and other fields to provide assistance for scene perception. However, because the noise and outliers of the sensor itself bring uncertainty to pose estimation and model building, which affects the modeling effect, the modeling effect of the existing positioning reconstruction methods is poor. Contents of the invention [0003] Embodiments of the present invention provide a positioning reconstruction method and device to solve the problem of poor modeling effect of existing positioning reconstruction methods. [0004] In a first aspect, an embodiment of the present invention provides ...
