The invention belongs to the technical field of intelligent and
robot operation, and discloses a collaborative
robot closed-loop operation method based on scene
perception and thinking chain reasoning, which comprises the following steps of: firstly, generating structured
semantic representation containing confidence by utilizing a visual
language model of LoRA efficient
fine tuning and fusing multi-view data, and providing semantic understanding for a
robot; secondly, utilizing a three-dimensional
diffusion model to generate explicit geometric priori under the condition of no real CAD, and correspondingly completing PnP initial
pose estimation in combination with 2D-3D; then, carrying out
pose optimization by adopting a tracking-refining strategy, and triggering reinitialization based on geometric prior when a residual error exceeds a threshold value; and finally, decomposing a global task by utilizing a thinking chain reasoning module, and realizing'
perception-reasoning-execution 'closed-
loop control based on visual
servo in cooperation with an execution module. The method realizes effective combination of
large model reasoning and physical execution, has strong robustness under dynamic disturbance, and is suitable for intelligent manufacturing and man-
machine cooperation scenes.
