Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] In order to facilitate understanding and description, the visual information is simplified in four points first, 1: the visual information is a general picture; 2: the picture records a plane object, that is, the height is zero; 3: the visual range is in a fixed spatial reference system In the range of positive values ​​of ; 4: The lens height is fixed; then, based on this, describe how the more general case translates into a simplified case.

[0018] see Figure 1 As shown, a fixed spatial reference system is composed of X, Y, and Z axes; a rectangle composed of points A, B, C, and D is a kind of visual information, here is a picture; point S is the center of the lens, That is, the position of the lens when taking this photo; point S' is the visual center, that is, ∠ASS'=∠CSS', ∠BSS'=∠CSS'; the vector composed of points S and S' is the direction of the lens, t...

Abstract

The invention relates to an asynchronous navigation method based on visual interaction. According to the method, firstly, how to pass through a simplified fixed space reference system, visual information and space instruction information is described, the space instruction information is converted into absolute space information in a fixed space reference system, the converted space information at least comprises the position and the direction, and absolute position information of any pixel in the visual information can be obtained; secondly, how to improve the algorithm is described, so that the algorithm is suitable for general situations; and finally, the characteristic that absolute space information of any pixel can be obtained through the algorithm is described, and how to obtain more space information such as the range is described.

Description

technical field [0001] The invention relates to the field of navigation, in particular to an asynchronous navigation method based on visual interaction. Background technique [0002] Existing visual navigation methods only use the position and / or some features in the visual information, and the visual information generally only includes the position and / or some specified features, but does not include position, direction, distance, and field of view coverage and other spatial information, but it is impossible to obtain the absolute spatial information at the relative angle and relative height of a specific area in the visual information through the existing visual information. Contents of the invention [0003] The purpose of the present invention is to directly obtain the absolute spatial information at the relative angle and relative height of a specific area in the visual information through the existing visual information. [0004] The purpose of the present invention...
