Embodiment Construction

[0049]It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] It should be noted that, in this document, the term "comprises", "comprises" or any other variant is intended to cover a non-exclusive inclusion such that a process, method, article or apparatus comprising a set of elements includes not only those elements, but also Other elements not expressly listed, or inherent to the process, method, article, or apparatus, are also included. Without further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising that element.

[0051] Herein, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "componen...

Abstract

The invention is suitable for the technical field of head-mounted display equipment, and provides a positioning mapping optimization method and device and a positioning mapping optimization chip, andthe method comprises the steps: responding to a positioning mapping instruction, calling a first transmission module to obtain an input image and a depth image, and calling a second transmission module to obtain sensor data; sending the input image to an image processing module to enable the image processing module to calculate a feature descriptor according to the input image; in the data packaging module, calling a timestamp generation module to add a first time label in the feature descriptor, add a second time label in the depth image and add a third time label in the sensor data; and calling a data packaging module to align the feature descriptor, the depth image and the sensor data according to the first time label, the second time label and the third time label, packaging the aligned data and outputting the packaged data so as to execute a positioning mapping instruction through an SLAM algorithm. According to the invention, the calculation load during the execution of the SLAMalgorithm can be reduced.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, in particular to a positioning and mapping optimization method and device, and a positioning and mapping optimization chip. Background technique [0002] The head-mounted display device is the best application environment for AR (Augmented Reality Technique, augmented reality technology), which can present virtual information in the real environment through the head-mounted device window. The current AR products have all-in-one AR glasses, which have a built-in battery, contain a complete computing processing unit and all electronic devices, and can work independently and meet the functional requirements of AR. [0003] The above-mentioned calculation processing unit usually combines SLAM (Simultaneous Localization and Mapping, real-time positioning and map construction) technology to realize visual positioning and map construction, but generally uses a general-purpos...
