Kind Code:
A1
Abstract:
Disclosed by embodiments of the present invention are a method for tightly-coupling visual SLAM, a terminal and a computer readable medium, wherein a QR code is fused with a current visual SLAM by means of a tightly-coupling fusion method, and monocular vSLAM is applied to an actual industrial robot so as to directly obtain a metric scale map and complete a locating operation of a camera. In addition, relocation and loopback detection may be quickly and accurately completed on the basis of a unique identifier (ID) of the QR code, thus effectively processing repeated textures in an environment, and obtaining a more robust system.
