Embodiment Construction

[0027] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention.

[0028] At present, the positioning principle of infrared positioning technology is: Infrared IR (Infrared) mark emits modulated infrared rays, and receives and locates through an optical sensor installed indoors. Although infrared rays have relatively high indoor positioning accuracy, infrared rays can only travel at a line-of-sight distance because light rays cannot pass through obstacles. The two major disadvantages of straight-line line-of-sight and short transmission distance make the effect of infrared positioning poor. When the infrared IR sign is placed in the pocket or when there are walls and other obstr...

Abstract

The present invention discloses a method and a system for realizing three-dimensional location, Wherein the method comprises the following steps: infrared rays transmitted by an infrared reference light source are received by an optical sensor; the position of the optical sensor corresponding to the infrared reference light source is ensured according to the property of the infrared reference light source in an image collected by the optical sensor to realize the three-dimensional corresponding location of the existing optical sensor. In the method and the system for realizing three-dimensional location, the position of the optical sensor corresponding to the infrared reference light source is ensured according to the property of the infrared reference light source in an image collected by the optical sensor, so not only the realization is simple, but also the cost is low compared with the prior art, a good location function can be provided to the application scene (for example, plausibility video) of corresponding location, and the experience of users is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of virtual video, and more specifically, to a method and system for realizing three-dimensional positioning. Background technique [0002] In recent years, positioning technology has developed rapidly, but most of them are outdoor positioning technologies. For example, a vehicle-mounted global positioning system (Global Position System, GPS) is a system for locating and navigating an external environment, and applying the system indoors cannot present an indoor environment. [0003] Indoor positioning technology is limited by conditions such as positioning time, positioning accuracy, and indoor complex environment, so there is no relatively complete positioning technology at present. Therefore, experts and scholars have proposed many indoor positioning technology solutions, such as A-GPS (Assisted GPS) positioning technology, ultrasonic positioning technology, Bluetooth technology, infrared technolo...
