1. Introduction: When High-Definition Imaging Meets Confined SpacesIn the intersection of minimally invasive medical procedures and industrial precision inspection, a common technical challenge increasingly arises: how to obtain sufficiently clear, smooth, and realistic visual information within a c

1. Introduction: When Detection Space Meets Device Volume ConstraintsIn the development of automated inspection equipment, specialized robots, and portable instruments, imaging system selection faces a fundamental contradiction: the target is deep inside narrow cavities, while control equipment is b

IntroductionIn industrial nondestructive testing, medical device development, and embedded vision systems, a recurring challenge arises when the target lies on the sidewall of a pipe or within narrow cavities, particularly at millimeter-scale diameters. Traditional forward-view endoscopes fail in su

OV9734 Sensor 3.6mm Micro HD Endoscope Camera Module: Engineering Guide for Confined-Space Vision SystemsIntroductionIn the realm of industrial inspection, precision equipment maintenance, and embedded vision systems, the ability to visualize the interior of narrow structures often determines the su
