Multi-target recognition method based on heatable marker

Target recognition is a difficult point in intelligently following mobile robots. This paper proposes a multi-target recognition method based on heating markers. The mark is made of carbon fiber material and multiple carbon fibers are arranged in parallel at the waist of the user. Set the order of the carbon fiber energization heating according to the binary rule to realize the function of encoding. The order of the carbon fibers for electric heating is set according to the binary rule to realize the function of encoding. The user can use the portable controller to adjust the temperature of the heating mark. The robot uses an infrared thermal imaging camera to detect the thermal radiation generated by the thermal mark from the front, rear, left, and right directions of the human body. The robot can obtain the position information of the distance heating mark through the ultra-wideband module integrated in the controller. Experiments show that the coded mark can be accurately identified and decoded, and it can meet the requirements of multi-target detection tasks.
