Problems solved by technology
[0004] These positioning methods will be affected by factors such as environment, climate, light, etc., and the scope of use is limited
The positioning methods of distance sensors such as ultrasonic, laser, and infrared ranging are greatly affected by the accuracy of the sensor; electromagnetic sensing positioning requires the laying of magnetic strips on the road where the robot needs to be positioned, which requires a huge amount of engineering, and the magnetic strips demagnetize quickly in hot and humid weather ;GPS positioning is accurate, but no occlusion

Embodiment Construction
[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] The all-weather mobile robot positioning system designed by the present invention is composed of a near-infrared panoramic lighting viewing device and a reference object with a characteristic encoding format, such as figure 1 As shown, the near-infrared panoramic lighting viewing device 1 is installed on the top of the robot 2, so as to observe the surrounding conditions. A number of reference objects 3 with characteristic encoding formats are distributed on both sides of the road 4 on which the robot travels. The near-infrared light 5 emitted by the near-infrared panoramic lighting viewfinder 1 is irradiated on the reference object 3, and the near-infrared light 6 reflected by the reference object 3 is reflected back into the camera of the near-infrared panoramic illumination viewfinder 1 for imaging. The characterist...

The invention relates to a movable robot positioning system which can run in all-weather, consisting of near infrared panoramic lighting and photographing device and a plurality of reference objects which are provided with characteristic coding formats, wherein, the near infrared panoramic lighting and photographing device is arranged on the top of the robot; a plurality of reference objects which have characteristic coding formats and are distributed at two sides of the road where the robot runs; the near infrared panoramic lighting and photographing device emits the near infrared and the near infrared radiates on the reference objects; the reflecting light is reflected into the camera of the near infrared panoramic lighting and photographing device and forms the image; by recognising and extracting the characteristic coding information of different reference objects and using a triangle positioning principle, the gesture of the robot is determined and the self-positioning of the robot is completed. The near infrared lighting and photographing of the invention adopt the principle of panoramic vision and can be completed in all-directions of 360 DEG, and run indoors and outdoors in all-weather.
Description
technical field [0001] The present invention relates to a mobile robot positioning system that operates around the clock, in particular to a mobile robot positioning system that can operate under all-weather conditions through near-infrared lighting and visual sensing Background technique [0002] Vision systems are very important sensing means in many fields, such as in security, surveillance, aerospace, transportation and other systems. For a long time, with the continuous advancement of technology, smart devices are replacing humans to complete certain dangerous, heavy and repetitive tasks, such as smart vacuum cleaners, smart lawn mowers, patrol robots, driverless cars and even automatic guided vehicles (AGV), etc. . However, due to the limitation of sensing conditions of such devices, they cannot be applied under changing environment, climate, light and other conditions, so the application of these devices is still limited at present. [0003] At present, the position...
