Embodiment Construction

[0086] The method and device of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0087] In the way of positioning through the method of image acquisition, by selecting some positioning auxiliary objects in advance, the positioning auxiliary objects can be ordinary objects in fixed positions (such as a vase), or some objects with special identification (such as two Two-dimensional code image), calibrate and store the position of the auxiliary positioning object, and when the user takes a photo of the auxiliary positioning object whose position information is known, recognize the auxiliary positioning object in the image and obtain the position information of the auxiliary positioning object Locate the user's location. However, since the location of the positioning assistance object is generally not the location where the user takes a picture, the positioning method that directly uses the location of the positioni...

Abstract

The invention discloses an image acquisition and positioning method and an image acquisition and positioning device. The method includes: a gaze confirmation step, confirming that the user's eyes are gazing at the positioning auxiliary object; an eye photographing step, photographing the user's eyes and obtaining the relative The distance of the positioning auxiliary object; the image acquisition step, collecting an image comprising the positioning auxiliary object; the information acquisition step, obtaining the direction information of the user relative to the positioning auxiliary object and the position information of the positioning auxiliary object according to the collected image; In the positioning step, the user's position information is obtained according to the position information of the positioning assistance object, the distance and direction information of the user relative to the positioning assistance object. The method and device of the present invention accurately locate the position of the user relative to the positioning auxiliary object by acquiring the distance and relative direction between the positioning auxiliary object that the user's eyes are looking at and the user, thereby improving the accuracy of image acquisition and positioning.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to an image acquisition and positioning method and device. Background technique [0002] Positioning technology has been widely used, such as the Global Positioning System (Global Positioning System, GPS) technology has been very mature, a large number of applications in navigation and other fields. However, the positioning accuracy of GPS is low, and the signal is weak in the indoor environment, so it is not suitable for indoor applications. Therefore, in recent years, many positioning methods, devices and systems suitable for indoor environments and different from GPS have been produced. For example, use the fading and transmission delay characteristics of electromagnetic waves (Bluetooth, WIFI, etc.), sound, visible light and other signals transmitted in the air to achieve positioning; it is also possible to achieve positioning according to the different magnetic field dist...
