Problems solved by technology

Once it is difficult to extract feature points from the object to be located, such as an object with rotational symmetry, the accuracy of object pose estimation will decrease, and even the pose estimation of the object cannot be performed.

Abstract

The embodiment of the invention provides a positioning, grabbing and data processing and display display method and device for augmented reality. The method comprises the following steps: acquiring ato-be-positioned image of a target object; and positioning the target object according to the first predicted pose of the reference object around the target object predicted based on the to-be-positioned image and the pose conversion relationship between the target object and the reference object by an instant positioning and map construction algorithm. According to the method provided by the embodiment of the invention, the rotationally symmetrical object can be effectively positioned, and the positioning accuracy and the positioning success rate are improved.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a positioning, capturing, data processing and display method and device for augmented reality. Background technique [0002] At present, in the technical fields such as robotics and augmented reality, it is necessary to estimate the pose of objects. For example: when a robot interacts with an object, it needs to estimate the pose of the object to determine the interaction method; another example: an augmented reality device needs to determine the pose information of the real object in order to determine how to render the virtual object. [0003] In the existing object positioning methods, real-time positioning and map construction algorithms are usually used to extract feature points from the object to be located and perform matching of feature points to realize object pose estimation. Once it is difficult to extract feature points from the object to be located...
