Problems solved by technology
[0002] Existing methods for locating objects can use ultrasonic waves (radar, sonar), image recognition, etc., but it is easier to encounter clutter when using ultrasonic methods for precise positioning in a small area (because sound waves bounce back and forth quickly in water) and The problem that the reflected plane is not vertical; and the use of image recognition requires huge calculations, which are basically based on computer systems and cannot be completed with embedded chips
In general, both have the disadvantages of high price, large overall volume, and complex calculations. In addition, the existing object positioning method cannot identify the specific orientation of the object, such as the head orientation of the object. In other words, the existing positioning method can only detect The position or movement of the object, but it is impossible to determine whether the object is moving backwards or forwards, that is, it is impossible to determine the direction of the head of the object

The invention provides an infrared ray location system and a location method. The location method comprises the following steps: at least a group of infrared ray units are arranged on a carrier; the infrared ray unit comprises at least two infrared ray emitters which emit infrared ray signals with different codes respectively; the infrared ray unit comprises at least a first processor which is electronically connected with the infrared ray emitter; the infrared ray signal is received by a receiving unit which is provided with at least two infrared ray receivers and a second processor; the infrared ray signal emitted by the infrared ray emitter is received by the at least two infrared ray receivers respectively; and the second processor judges the location and the direction of the carrier according to the received infrared ray signal.
Description
technical field [0001] The invention relates to an infrared ray positioning system and a positioning method, in particular to a positioning system and a method that can identify the head orientation of an object and accurately determine the moving forward, backward or turning of the object. Background technique [0002] Existing methods for locating objects can use ultrasonic waves (radar, sonar), image recognition, etc., but it is easier to encounter clutter when using ultrasonic methods for precise positioning in a small area (because sound waves bounce back and forth quickly in water) and The problem that the reflected plane is not vertical; and the use of image recognition requires huge calculations, which are basically based on computer systems and cannot be completed with embedded chips. In general, both have the disadvantages of high price, large overall volume, and complex calculations. In addition, the existing object positioning method cannot identify the specific ...
