Problems solved by technology

[0010] (2) Existing methods all use voice and keyboard as the input method, and the operator cannot concentrate all his attention on the disassembly operation, so it is centered on the computer;

[0011] (3) Due to the large changes in the disassembly and assembly scene during the disassembly and assembly of the device, and the movement of the hand will cause the occlusion of the feature points, resulting in the reduction of matching pairs of feature points, which greatly reduces the robustness of the traditional optical tracking method based on natural feature points , so the existing disassembly and assembly induction methods all use special equipment to artificially set up identification points to realize augmented reality registration

[0012] The above three problems limit the universality, portability and human-computer interaction of complex mechanical equipment disassembly guidance system
