Problems solved by technology

That is, in the spatial positioning method of rolling shutter camera fusion IMU, the influence of rolling shutter camera on moving images is not considered. Although this assumption can simplify the processing process, it also ignores the problems caused by inconsistent image acquisition time, such as The accuracy of spatial positioning is low and the positioning effect is poor, so in applications such as AR / VR, virtual scenes or objects are constantly shaking.

Abstract

The embodiment of the invention provides a spatial positioning method and device, electronic equipment and a computer readable storage medium, and relates to the technical field of the big data. The spatial positioning method can be applied to intelligent equipment comprising an image collection device and an inertial measurement device, and comprises the following steps: acquiring image collection device pose information corresponding to the current frame image; optimizing the image collection device pose information corresponding to the current frame image according to the image collection device pose information corresponding to a key frame image, feature point description information and the inertia information; and acquiring the spatial positioning of the current frame image accordingto the optimized image collection device pose information corresponding to the current frame image and the image collection device pose information corresponding to the key frame image. The spatial positioning precision and positioning effect can be improved through the spatial positioning method provided by the invention.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of big data, and more specifically, embodiments of the present invention relate to a spatial positioning method, a spatial positioning device, electronic equipment, and a computer-readable storage medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] According to the camera and IMU (Inertial Measurement Unit, Inertial Measurement Unit) and other sensors attached to the mobile phone and head-mounted device, the spatial positioning of the device is performed. This is the current relatively common inside-out device positioning method, which can be applied to VR (Virtual Reality, virtual reality) equipment, AR (Augmented Reality, augmented reality) equipment, and smart device navigati...
