Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the drawings and examples.

[0036] The definitions of all code names in the specific embodiment of the present invention are as follows:

[0037] OpenGL (English: Open Graphics Library, translated name: Open Graphics Library or "Open Graphics Library") refers to a cross-language, cross-platform application programming interface (API) for rendering 2D and 3D vector graphics. This interface consists of nearly 350 different function calls used to draw complex 3D scenes from simple graphics bits. Yet another program interface system is Direct3D on Microsoft Windows only. OpenGL is commonly used in CAD, virtual reality, scientific visualization programs, and video game development. Efficient implementations of OpenGL (that take advantage of graphics acceleration hardware) exist on Windows, some UNIX platforms, and Mac OS.

Abstract

The invention provides a method and a device for measuring distances based on a motion-sensing camera as well as a storage medium. The method comprises the following steps: obtaining color flow and depth flow by using the motion-sensing camera, then drawing a color-depth composite images by using an OpenGL (Open Graphics Library), dragging a mouse to obtain camera coordinates of any two points inthe image, and converting coordinates of two points from a camera coordinate system to a world coordinate system according to inner parameters of the camera so as to solve an actual distance between the two points. The method and the device are capable of accurately calculating the space distance between any two points in an effective operation range of a depth sensor in real time, and are simpleand convenient to operate.

Description

technical field [0001] The invention belongs to the application field of somatosensory technology, relates to the field of image processing and computer vision, and in particular relates to a method for measuring distance based on a somatosensory camera, a device for measuring distance based on a somatosensory camera, and a device. Background technique [0002] As an industry that is particularly prominent in the current development stage, somatosensory technology is also an important development direction in the future. With the application and development of intelligent monitoring in machine vision in the practical field, people detection and tracking technology using cameras has made great progress, but more research is still needed on the use of cameras for distance measurement. In daily life, measuring distance has a very wide range of usage scenarios, such as measuring the length and width of books, measuring the height of tables and chairs, measuring the height of ind...
