Problems solved by technology

[0008] Aiming at the problem that traditional 3D laser radar and binocular camera fusion are used for robot path planning, the price of 3D laser radar is too high and it is not applicable in many occasions. The present invention provides a robot path based on data fusion of single-line laser radar and binocular camera. Planning method; the present invention adopts a calibration method, fits an error function, performs error correction on the point cloud of binocular vision, and then projects the point cloud to obtain the used point cloud projection, thereby completing the path planning of the mobile robot

Embodiment 1

[0038] combine figure 1 , in order to realize a robot path planning method based on single-line laser radar and binocular camera data fusion in this embodiment, a robot equipped with 2D laser radar and binocular camera is designed. Built as a whole, the 2D laser radar 2 and the binocular camera 3 are placed on the central axis of the mobile robot. The robot is equipped with HCR robot platform 4, bottom motion controller 5, development board 6 (JETSON TX2 development board), main controller 7 and wireless network card 8 at the same time.

[0039] In this embodiment, the mobile robot uses 2D laser radar and binocular camera fusion on the basis of SLAM to complete the construction of accurate dense point cloud, thereby completing the path planning of the mobile robot.

[0040] The SLAM algorithm is the basis of this embodiment. Accurate SLAM dense point cloud construction plays an important role in the later data fusion. However, this embodiment uses binocular vision SLAM, so th...
