Embodiment Construction

[0033] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0034] In order to realize the spatial positioning of an electronic device based on an image, an embodiment of the present invention provides an image information processing method, which is applied to a first electronic device, such as figure 1 As shown, the method includes:

[0035] Step 101, receiving and saving the first image uploaded by the second electronic device.

[0036] Since this method is applied to the first electronic device, the execution subject of step 101 is the first electronic device, then, step 101 can also be described as: the first electronic device receives and saves the first image uploaded by the second electronic device . The first image may be a 2D image or a 3D image.

[0037] Step 102, constructing a three-dimensional coordinate map, and extracting feature points from the first image...

Abstract

The invention discloses information processing methods, systems and devices. A method applied to first electronic device comprises the steps of receiving and saving first images uploaded by second electronic device; establishing a three-dimensional coordinate map, conducting feature point extraction to the first images based on the established three-dimensional coordinate map, analyzing and saving feature point description information of corresponding feature points, and determining and saving the spatial position information of the extracted feature points in the three-dimensional coordinate map; establishing a feature point dataset based on analyzed and saved feature point description information of a first quantity of first images and the determined and saved spatial position information of the feature points. By using the information processing methods, the systems and the devices, the spatial positioning of electronic devices based on images is realized.

Description

technical field [0001] The present invention relates to the technical field of image-based positioning, in particular to an image information processing method, system and device. Background technique [0002] Positioning technology is currently widely used in people's daily work and life, and most of the current mature positioning technologies are not very accurate. Image-based positioning technology is the current research direction, and how to achieve high-precision positioning based on image information processing is an urgent problem to be solved. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide an image information processing method, system and device, so as to at least realize image-based spatial positioning of electronic devices. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] An image information processing method applied to a f...
