The present application relates to the technical field of intelligent medical teaching, and provides an internal examination teaching method for real-time acquisition of cervical pressure data, comprising: S1: building an overall structure of an intelligent internal examination teaching aid; S2: using pressure sensor integration and calibration technology to implement real-time acquisition of high-precision pressure data and three-dimensional coordinate data on the vaginal wall and cervical part; S3: using real-time visualization algorithm for internal operation of the vagina to convert the collected spatiotemporal mechanics signals into three-dimensional motion trajectory, force distribution and dynamic rendering image; S4: constructing a multi-dimensional quantitative evaluation index system, and based on the expert standard operation library and the similarity algorithm, objectively quantifying the score and standardizing the judgment of the operation of the student; S5: realizing real-time fitting, trajectory rendering and multi-dimensional information display of the operation data; S6: executing internal examination simulation training, data acquisition, real-time feedback and comprehensive examination. Through the built-in pressure sensor, the position and mechanics change information of the operation method are collected in real time, and the operation of the student is objectively quantified and judged.

This utility model provides an internal inspection device for welded joints of pipe components in pressure vessels, relating to the field of pipe component inspection technology. It includes a frame, with a Keyence vision inspection and automatic detection assembly mounted on the top of the frame. An endoscope display screen is mounted on the outer wall of the Keyence vision inspection and automatic detection assembly, and a probe positioning fixture is mounted on the output end of the assembly. The automatic inspection equipment for pipe components uses the probe positioning fixture to internally photograph the cross-section of the welded joint, and a rotating disk rotates the main body of the pipe component to achieve circumferential inspection of the welded joint. The Keyence vision inspection and automatic detection assembly then automatically photographs the inspection images, and the product's conformity is determined based on the inspection criteria set on the assembly. This ensures timely detection of defective products, guarantees finished product quality, and the probe positioning fixture performs the function of positioning the cross-section of the welded surface of the pipe workpiece.

The present invention discloses a system and method for automatic defect inspection and operator assessment in a circular knitting machine (104). The system comprises at least one an external camera (102) to capture at least one image of surroundings of a circular knitting machine (104). Further, the system may comprise an internal inspection unit (106) to analyze at least one captured image to detect defects in the fabric and / or data collection unit attached to knitting machine. Furthermore, the system may comprise an automatic defect processing unit (110) to receive the at least one analyzed image data from the internal inspection unit (106) for decision making Additionally, the automatic defect processing unit (110) classifies the detected defects into preventable defects and non-preventable defects. Thereafter, the automatic defect processing unit (110) based on the classification determines whether to stop the circular knitting machine (104) or to trigger an alert for operator intervention.

This invention provides a technique for obtaining image data covering the entire circumference of the inner surface of an object to be inspected by irradiating it with light and taking images using the light section method. [Solution] An internal inspection device for imaging the inner surface of a hollow object under inspection comprises an imaging unit, a transparent fixing member, a light source, and a first mirror. The imaging unit is inserted into the inside of the object under inspection and is capable of imaging the inner surface of the object under inspection. The fixing member is fixed to the imaging unit, located radially outside the imaging unit, extends axially along the optical axis of the imaging unit, and is inserted into the inside of the object under inspection together with the imaging unit. The light source emits laser light directed toward one side in the axial direction. The first mirror reflects the laser light emitted from the light source and propagates it radially outward along its entire circumference. One end of the fixing member in the axial direction is located one side further axially than one end of the imaging unit in the axial direction. The first mirror is fixed to the fixing member one side further axially than one end of the imaging unit in the axial direction.
