Problems solved by technology

[0004] However, in order to cover all regions of interest (ROI) of mechanical devices, it usually takes several days
Guiding the imprecise position of the probe in the mechanism is a major cause of wasted time
Due to navigation errors, the operator cannot control the probe head to the area of ​​interest according to the navigation information or cannot control the micro-camera to face the desired direction

Abstract

The borescope includes an insertion tube, a first image processor (304), a model store unit (306), a pose calculator (307), a second image processor (314), a navigation image calculator (310) and a display (220). The insertion tube includes a detection head (242) and at least one sensor (2465) for receiving signals in the insertion tube and generating sensed signals (316). The first image processor (304) is for calculating a first image (312) based on first image signals (311) captured by the detection head (242). The second image processor (314) is for adjusting the initial pose (317) calculated by the pose calculator (307) to a navigation pose (324) until a difference between the first image (312) and a second image (322) calculated based on the navigation pose (324) and a predetermined model (318) falls in an allowable range. The navigation image calculator (310) is for calculating a navigation image (325) based on the navigation pose (324) and the predetermined model (318). The display (220) is for showing the navigation image (325).

Description

technical field [0001] The invention relates to a borescope (Borescope), in particular to a borescope for precisely positioning the position of a probe head of the borescope in a detected mechanical device and a navigation method thereof. Background technique [0002] Borescopes (industrial borescopes) are widely used in the inspection of mechanical devices such as aeroengines, industrial steam turbines, internal combustion engines or automobile engines. Considering safety and maintenance needs, it is necessary to regularly check the internal components of the mechanism for failure. [0003] Flexible borescopes are often used to inspect complex internal surface structures of mechanical devices. In some cases, one end of the flexible detection tube of the borescope is provided with a detection head, which may include a miniature camera and a light source to capture clear dynamic or static images in the dark space of the mechanical device under inspection. As a remote monito...
