Abstract

The invention discloses a mobile robot indoor positioning system based on an infrared road sign. The system is structurally characterized in that: a dot matrix road sign is manufactured by using an infrared emitting diode and is adhered to an indoor ceiling; a wide-angle infrared camera is fixed on the body of a mobile robot to shoot the infrared road sign upwards; and a computer on the body of the robot performs image analysis and calculates out the position and pose of the robot in real time. The positioning system disclosed by the invention can be used for the positioning of the mobile robot at indoor places with a relatively large range, and has the characteristics of fast calculation speed, high positioning accuracy and strong anti-interference performance.

Description

technical field [0001] The invention relates to the technical field of infrared imaging, in particular to the technical field of visual positioning of mobile robots. Background technique [0002] With the rapid development of computer technology, VLSI technology, network technology, artificial intelligence technology, etc., robot technology has also developed by leaps and bounds. There are more and more types of robots, and the scope of application is also wider and wider. In 2007, Microsoft President Bill Gates predicted in the "Scientific American" magazine that robots will enter thousands of households just like personal computers 30 years ago. South Korea's Samsung Economic Research Institute once predicted that by 2020, the world's robot market will reach 1.4 trillion US dollars. The Ministry of Information and Communication of South Korea even set an amazing goal of having a robot in every household by 2020. For an intelligent mobile robot, in order to efficiently wa...
