In the indoor environment, the previous artificial landmark design scheme is complex in recognition algorithm with low accuracy, and it is hard to meet the real-time requirements. In view of such problems, two new kinds of artificial landmarks are designed in this paper:location artificial landmark and correction artificial landmark, which can not only help the indoor mobile robot to navigate and rectify, but also have the advantages of simple and rapid identification. The robot can identify location artificial landmark in real time, and adjust its position and movement direction according to the correction artificial landmark, so that the robot can move forward smoothly along the planned path. Experiments show that in dark, moderate, strong light indoors, the recognition of two kinds of artificial landmark is highly accurate and fast, which can meet the requirements of real-time navigation.
