Embodiment Construction

[0065] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0066] Such as figure 1 As shown, it is a schematic flowchart of a space ranging method for a mixed reality device provided by an embodiment of the present invention, and the method includes the following steps:

[0067] S101, selecting an object to be measured by selecting a module, the object to be measured may be an object to be measured with an irregular surface;

[0068]S102. The first ranging module randomly selects any point on the object to be measured as a reference point, and measures the distance between the reference point and the mixed reality device to obtain a reference distance;

[0069] S103, the second ranging module acquires the grayscale depth-of-field image of the object to be measured, and can...

Abstract

The invention relates to a space ranging method and system for mixed reality equipment. The method includes the following steps that an object to be measured is selected; any point on the object to be measured is selected as a reference point; the distance between the reference point and the mixed reality equipment is measured to obtain the reference distance; a gray level field depth graph of the object to be measured is obtained; the distance between any point on the object to be measured and the mixed reality equipment is obtained according to the reference distance and the gray level field depth graph. The space ranging method and system for mixed reality equipment can fast obtain the distance of any point on the surface of the object to be measured and have the advantages of being high in ranging speed and high in ranging accuracy.

Description

technical field [0001] The present invention relates to the field of mixed reality, in particular to a space ranging method and system for mixed reality equipment. Background technique [0002] Mixed reality products are superimposing computer-generated images with the real world, displaying images in virtual space in real space, so that human eyes can see virtual objects in the real world. Among them, the more representative product is HoloLens, a wearable mixed reality computing device released by Microsoft. [0003] Currently, there are mainly the following ranging methods for mixed reality products: [0004] 1) Distance measurement by stereo vision technology. [0005] Obtain the depth map of the surrounding environment through two cameras, and get the distance between the object in the real scene and the camera from the image data of the two cameras, but this method is not enough to measure only one depth map, it is only true at a certain moment The mapping of the sc...
