Working principle and application scenarios of endoscopic camera system measurement
Date: 2025-10-13Read: 1
Endoscopic camera system measurement, as an important measurement tool, has played a huge role in fields such as medicine, industrial testing, and environmental monitoring. With the continuous advancement of image processing technology, optical technology, and computer technology, the measurement accuracy and application range of endoscopic camera systems are also constantly expanding.
Endoscopic camera system measurementThe principle:
1. Two dimensional image measurement: By capturing two-dimensional images through an endoscope and combining them with known calibration data, the size and shape of an object can be directly measured. For example, in medical endoscopes, precise size measurements of tumors, ulcers, and other lesions can be made using a reference ruler in the image.
2. 3D image measurement: With the development of 3D endoscopic technology, 3D image measurement has become an important function of endoscopic camera systems. A 3D endoscope captures objects from multiple perspectives and obtains three-dimensional data of the target area through image reconstruction techniques, thereby achieving more accurate stereo measurements. For example, a 3D endoscope can obtain detailed 3D structures of the affected area when detecting gastrointestinal lesions, helping doctors make more accurate diagnoses.
3. Optical calibration: Measurement accuracy depends on the accuracy of optical calibration. Usually, endoscopic systems undergo optical calibration at the factory, which includes calibration of camera resolution, lens distortion, field of view, and other parameters. In order to improve measurement accuracy, the endoscope system can also perform dynamic calibration, which adjusts the measurement algorithm based on real-time images and corrects errors caused by changes in lighting, angle, etc.
Application of endoscopic camera system measurement:
1. Medical field: Endoscopic technology is the most widely used in medicine. Especially in minimally invasive surgery and early disease diagnosis, endoscopic imaging systems have played an important role. Through real-time images captured by cameras, doctors can clearly observe lesions or abnormal conditions in the body and make real-time measurements and judgments. The measurement function, especially in tumor resection, biopsy and other surgeries, can help doctors accurately locate diseased tissue, improve the success rate and accuracy of surgery.
2. Industrial testing: It also has a wide range of applications in the field of industrial testing, especially in equipment and pipeline testing that is difficult to observe directly, such as industries such as oil, natural gas, electricity, aviation, etc. Through the endoscopic camera system, staff can quickly obtain high-definition images of the interior of pipelines, mechanical equipment, and other locations for real-time monitoring and evaluation, detect potential faults and damages in advance, and avoid the risk of manual entry into hazardous areas.
3. Environmental monitoring: It can also be applied in the field of environmental monitoring. For example, groundwater quality testing in geological exploration and smoke capture in forest fire monitoring. Through high-precision endoscopic cameras, relevant personnel can remotely observe these difficult to directly contact environments and obtain key information in a timely manner.
