Embodiment Construction

[0053] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0054] In the prior art, mainly by laying the calibration plate on the ground, the camera captures the image including the calibration plate laid on the ground, so as to recognize the image, so as to realize the top view. However, since the installation direction of the camera is generally parallel to the ground or the angle with the normal line of the ground is greater than 60 degrees...

Abstract

The invention provides a method and device for rotating a camera to a top view and a storage medium. The method comprises the steps: recognizing images of a plurality of calibration plates which are vertically arranged on the ground and are obtained by the camera, obtaining the respective identification information of each calibration plate, determining a space origin according to the feature points of two calibration plates which are arranged on the ground side by side, converting pixel coordinates of each feature point into space coordinates according to a space origin and a right-handed coordinate system rule, constructing 2D-3D point pairs corresponding to the pixel coordinates of the plurality of feature points and the space coordinates according to the plurality of identifiers, calculating the 2D-3D point pairs through a PNP pose algorithm to obtain installation coordinates of the camera. projecting the point where the installation coordinate of the camera to the ground serves as the original point, converting the space coordinate of each feature point according to the preset size information of the top view and the original point, and obtaining the pixel coordinate of each feature point in the top view. The technical effect of accurate and reliable conversion is achieved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a method, device and storage medium for turning a camera to a top view. Background technique [0002] In recent years, intelligent transportation has become a research hotspot, and the assisted driving system, as an important part of intelligent transportation, has attracted much attention. [0003] In the prior art, the method of turning the camera to the top view is mainly to lay a calibration board on the ground, select the mark points on the calibration board as feature points, and determine the spatial coordinates of at least four points on the plane and their positions on the image based on the feature points. The pixel coordinates are obtained from the imaging of , and the point pairs of two conversion planes are formed, and the image is converted into a top view according to the point pairs. [0004] However, in the process of implementing the present disc...
