Problems solved by technology

[0002] Existing electronic devices with projection function and operation collection function need to calibrate the coordinate systems of different collection modes before use. Since the information collected in different collection modes in the prior art cannot be used universally, therefore, before use During the calibration process, the conversion and association of information collected under different collection modes is relatively cumbersome.

Abstract

The invention discloses an information processing method, comprising the following steps of: projecting at least one reference point on a bearing surface by using visible light; acquiring, in the bearing surface, a first coordinate of the reference point in a first coordinate system in the mode of visible light collection; acquiring, in the bearing surface, a second coordinate of the reference point in a second coordinate system in the mode of infrared collection; and establishing a mapping relationship between the first coordinate system and the second coordinate system, wherein the mapping relationship between the first coordinate system and the second coordinate system is used for collecting operations on the bearing surface, and updating the contents displayed by projection on the bearing surface according to the collected operations. The invention further discloses an information processing device.

Description

technical field [0001] The invention relates to electric digital data processing technology, in particular to an information processing method and equipment. Background technique [0002] Existing electronic devices with projection function and operation collection function need to calibrate the coordinate systems of different collection modes before use. Since the information collected in different collection modes in the prior art cannot be used universally, therefore, before use During the calibration process, the conversion and association of information collected under different collection modes is relatively cumbersome. Contents of the invention [0003] Embodiments of the present invention provide an information processing method and device, capable of automatically performing calibration operations on electronic devices with projection functions and operation collection functions before use. [0004] The technical scheme of the embodiment of the present invention ...
