Problems solved by technology

[0003]In a narrow space, the photographic tools used by operators are usually small in size and have a limited field of view. It takes time to find the operating object; and under unfavorable working conditions (temperature, light, etc.), the recognition of the operating object is not high, and the operator needs to identify the operating object
These factors lead to long operating process times and increased operational risk

Embodiment Construction

[0017] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the embodiment of the present invention provides a navigation system, which is used for the user to provide navigation for the operation of applying tools to objects in a narrow space, which includes: a labeling module, and the labeling module The key parts of the object are marked in the original three-dimensional model of the object; the shooting module follows the tool into the narrow space and takes real-time shooting of the object in the small space, and the shooting module instructs the tool The current position on the object; a modeling module, the modeling module uses the real-time data obtained by the above-mentioned shooting module to establish a real-time three-dimensional model of the object; a registration module, the registration module converts the object's The original three-dimensional m...

Abstract

The invention discloses a navigation system, which comprises a labeling module, which is used for labeling a key part of an object in an original three-dimensional model of the object; a shooting module which enters the narrow space, shoots the object in real time and indicates the position of the tool on the object; a modeling module which is used for establishing a real-time three-dimensional model of the object; a registration module which is used for registering the original three-dimensional model and the real-time three-dimensional model to obtain relative position information between the key part of the object and the current position of the tool; and a navigation module which is used for navigating the user based on the relative position information. By means of the system, the time for a user to find a key part can be shortened, operation time is shortened, and operation risks are reduced.

Description

technical field [0001] Embodiments of the present invention relate to a navigation system. Background technique: [0002] In an industrial operating environment, due to temperature, occlusion or space factors, the operator sometimes cannot directly look at the object to be operated, and needs to use photographic aids (such as an endoscope) to assist in the operation. [0003] In a narrow space, the photographic tools used by the operator are usually small in size and have a limited field of view. At this time, the operating object may be outside the field of view of the photographic tool, and the operator needs to spend time looking for the operating object; and in unfavorable working conditions (temperature , light and other conditions), the recognition of the operating object is not high, and the operator needs to identify the operating object. These factors lead to long operating process times and increased operational risk. Contents of the invention [0004] The purp...
