Wearable visual fixation target positioning device and a method thereof

Abstract

The invention relates to a wearable visual fixation target positioning device and method, the hardware portion includes a shoulder support bracket, Rotating shaft and angle sensor, Neck rotating clasp, vision sensor, microprocessor, for data reception and processing, the device was placed on the subject, First, the angular orientation of the head and neck position is obtained, so that that visualgaze direction is obtain, Synchronize the vision sensor with the visual orientation by turning the snap ring around the neck. so that the vision sensor is synchronized with the front-view direction ofthe person, Two-dimensional machine vision positioning technology and depth information are used to determine the spatial position of the object in the gaze field, and the position information of theobject is obtained through coordinate transformation and visual gaze orientation information fusion, and then the three-dimensional information is converted to the required application coordinates. The device can be used for realizing the visual active selection target of human-machine mixing and determining the spatial coordinate position of the target relative to the body.

Description

technical field [0001] The invention belongs to the field of three-dimensional positioning and recognition of a fixation target, and relates to a wearable visual fixation target positioning device and method. Background technique [0002] The three-dimensional expansion of the field of view, three-dimensional positioning in machine positioning is currently a hot part of research. Machine vision mainly uses computers to simulate human visual functions, extract information from images of objective things, process and understand them, and finally use them in practice Detection, measurement and control, the biggest feature of technology is fast speed, large amount of information, and many functions. The research of machine vision started from the research of American scholar L.R. Roberts in the mid-1960s on understanding the world of building blocks composed of polyhedrons. In foreign countries, the popularity of machine vision applications is mainly reflected in the semiconduc...

Problems solved by technology

Similarly, in terms of using more advanced human-computer interaction, there is no relevant research report in China for the time being. Some foreign companies can use eye trackers to mark coordinates on a plane, which can be used for commercial purposes, but the structure is complicated and the cost is high.
