The embodiment of the invention provides an infrared detection location method. The method comprises: obtaining a first time point of an infrared emitter emitting infrared ray to an object; obtaining a plurality of second time points of the infrared ray, reflected by the object, received by a plurality of infrared receivers; determining a plurality of time differences based on the first time points and a plurality of second time points; and determining the position of the object at least based on at least part of time differences in a plurality of time differences and the relative position of the infrared emitter and a plurality of infrared receivers. The embodiment of the invention further provides a corresponding system. The infrared detection location method and system provided by the embodiment of the invention, compared to the prior art, can perform image process with no need for devices such as an infrared camera and the like and only need to allow the processor to calculate the obtained data to obtain the position of the object, and therefore, the device is low in cost, the processor algorithm is relative simple, and the timeliness is high.
Description
technical field [0001] The invention relates to the technical field of signal detection, in particular to an infrared detection and positioning method and system. Background technique [0002] Somatosensory recognition technology has attracted widespread attention with the hot sale of Microsoft's Xbox360 Kinect somatosensory system. With the deepening of the development of motion recognition system, it is foreseeable that the future motion recognition technology will be widely used in various fields such as industrial manufacturing, human-computer interaction, entertainment, multimedia, game applications, and shopping. [0003] At present, the more common somatosensory technologies include structured light, TOF (Time of Flight) and binocular vision technology. The basic principle of structured light technology is: load a laser projector, put a grating engraved with a specific pattern outside the laser projector, and the laser will be refracted when it is projected through t...
