Problems solved by technology

In the existing spatial positioning schemes, for the sake of accuracy, laser radar is usually used for spatial positioning. However, in some occasions (such as military occasions), for safety reasons, it is not allowed to use laser radar for spatial positioning. How to use ordinary image acquisition devices and recognition algorithms to meet the needs of high-precision spatial positioning and a wide range of applications has become an urgent technical problem to be solved

Abstract

The invention discloses a three-dimensional space positioning method, system and storage medium based on two-dimensional images, wherein the method includes: acquiring a two-dimensional image of a target object as a first image; extracting each target pattern in the first image; judging each After the target pattern is matched with the standard pattern, the characteristic data of each target is obtained, and the first projection relationship is determined; the first image is registered to the second image according to the first projection relationship, and then the deflection angle and deflection angle of the target object are determined and output. Move distance value. By taking the target object provided with the calibration object as the first image, after judging that the pattern of each target matches the standard pattern, the feature data of each target is extracted, and the first projection relationship is determined by the feature data of each target. According to the first projection relationship The first image is registered to the second image, and then the spatial positioning and measurement of the three-dimensional target is realized through the two-dimensional image, thereby improving the recognition accuracy range of the target object and reducing the cost.

Description

technical field [0001] The present invention relates to the technical field of space positioning, in particular to a three-dimensional space positioning method, system and storage medium based on two-dimensional images. Background technique [0002] It is an effective spatial positioning scheme to combine the image acquisition device and the graphic image algorithm for spatial positioning. Spatial positioning technology is a widely used auxiliary control method, which provides an effective feedback scheme for the calibration object without the user directly touching the calibration object. In the existing spatial positioning schemes, for the sake of accuracy, laser radar is usually used for spatial positioning. However, in some occasions (such as military occasions), for safety reasons, it is not allowed to use laser radar for spatial positioning. How to use ordinary image acquisition devices and recognition algorithms to meet the needs of high-precision spatial positioning...
