Problems solved by technology

However, the existing calibration methods are relatively complicated and difficult for ordinary users to master. Therefore, some equipment manufacturers that integrate 3D cameras often fix the 3D camera at a certain position on the electronic equipment, and do not allow users to move it at will. The positional relationship between the camera and the screen of the electronic device is well measured, and the relevant parameters are permanently retained in the electronic device, and the user can directly use the electronic device without calibration
However, the above method restricts the user to the parameter configuration of the 3D camera when it leaves the factory, such as the field of view, the resolution and definition of the captured image, etc., thus limiting the user's freedom of use and reducing the user experience.

Abstract

The embodiment of the invention discloses a method for calibrating the relative position relation between an image collection device and a display screen. The method comprises the steps that a pattern is displayed on the display screen of electronic equipment; a collected image is obtained through the image collection device, wherein the collected image comprises an image corresponding to a mirror and a virtual image, presented in a physical imaging mode, of the pattern; the collected image is analyzed, and the relative position relation between the image collection device and the display screen is determined; based on the relative position relation, the space operation, collected by the image collection device, of an operating body corresponds to the display screen to be responded. The embodiment of the invention further discloses the electronic equipment.

Description

technical field [0001] The invention relates to information processing technology, in particular to a method for calibrating the relative positional relationship between an image acquisition device and a display screen and electronic equipment. Background technique [0002] At present, three-dimensional (3D) camera technology is developing rapidly. With the continuous reduction of volume, continuous reduction of power consumption and cost, continuous improvement of precision, continuous improvement of related application services and ecosystems, and the continuous improvement of major manufacturers such as Intel and Microsoft With vigorous promotion, 3D camera products have gradually shifted from laboratory and industrial applications to the personal consumer market, becoming a popular product. [0003] Since the virtual world in an electronic device is generally built around the screen of the electronic device as a reference frame, and the real 3D world perceived by the ele...
