Description

Technical Field

[0001] This utility model belongs to the field of industrial testing equipment technology, and more specifically, it relates to a handheld industrial endoscope based on multimodal detection. Background Technology

[0002] Currently, in industrial production and equipment maintenance, it is often necessary to inspect the internal condition of components that are difficult to observe directly, such as pipes and engine interiors. Traditional industrial endoscopes are mainly used for visual inspection, acquiring internal images through cameras to check for foreign objects, damage, and other issues. However, relying solely on visual inspection has certain limitations; it cannot accurately detect defects hidden within materials, such as micro-cracks or changes in material thickness.

[0003] Existing flaw detection and thickness measurement equipment are often separate. In actual inspection work, staff need to carry multiple devices and manually adjust the inspection direction and position, which is cumbersome and inefficient. Moreover, it is difficult to effectively integrate and analyze the data from different devices, which is not conducive to a comprehensive understanding of the condition of the inspected parts. In addition, the equipment is bulky, inconvenient for outdoor work, and not convenient to operate. Utility Model Content
