DVS700B1 Gun Bore Intelligent Inspection System

Product Features:

High precision: dynamic video pixels up to 12 million, circumferential tilt accuracy ±1°, distance positioning accuracy ±3%, (defect) size measurement accuracy ±5% for type A and ±0.1mm for type B.

HD imaging parallel synchronous processing: can achieve simultaneous HD video imaging, video recording, unfolding and other functions in up to 3m/min travel, greatly improving work efficiency.

The use of special optical processing of high-speed panoramic camera, with multi-angle adjustable light source, to ensure that the whole circumference of the line in a one-time fast and clear imaging, improve the efficiency of detection and completely eliminate the multi-lens or rotating lens leak detection and perspective blind areas.

The professionally designed "centering support mechanism" ensures the stability of travel and image, and enables clear observation of all parts of the tube chamber.

Real-time unfolding and post-stitching to 2D cutaway, with superimposed length scale and circumferential angle scale functions.


This system is a macroscopic inspection equipment applicable to the inner surface of the pipeline designed with advanced technology based on the latest image processing research results. Aiming at the current situation of pipeline inspection, it fully takes into account the actual needs of field operation environment and usage conditions, and integrates functions such as high-speed HD video, intelligent motion positioning, defect measurement and editing, image unfolding and splicing. The equipment has the characteristics of strong anti-interference, high precision, high repeatability, good effectiveness and convenient operation, and its outstanding characteristics of "functional integration, easy operation and remote operation" make the accuracy and efficiency of macroscopic inspection of the internal surface greatly improved. At present, it has received practical praise from many units, such as: Weapons Research Institute, Weapons Testing Center, Artillery Manufacturing (such as North Heavy Industries Group), etc.


Functional features

lWith axial distance and circumferential inclination positioning function, it is convenient to repeat observation of suspicious areas.

lWith (defect) size measurement function, it can measure information such as length, width, area, and (type B only) height and depth of the marked area.

lWith real-time local zoom in, zoom out, mark and note text (multiple colors, multiple font sizes) and other functions, easy to observe details and record defects.

lWith (crackle enhancement) grayscale negative, contrast adjustment, brightness adjustment, tone curve adjustment, monochrome channel separation, angle rotation and other viewing enhancement functions.

lPortable cable holder, with detachable, high brightness (visible in the sun), high-definition large-screen industrial control panel, fully considered the field operating environment and use conditions.

lThe integrated probe mechanism is characterized by strong anti-interference capability and high moisture, dust and shock resistance.

lThe host has a built-in quad-core processor, which can acquire image data, axial travel distance and circumferential tilt attitude data at the same time, which can ensure real-time acquisition of high-definition panoramic images, fast and seamless unfolding and post-splicing into 2D profile maps.

lThe host operating software has functional modules such as human-computer interaction, user management, parameter input, report generation and output/printing, data maintenance and backup, operation log, online help, etc.

Comparison with ordinary endoscope

The existing gun barrel borescope on the market, mostly using the traditional endoscope or simple tooling modification of the endoscope, single function, blurred image / low pixel, can not be centered and feeding difficulties, easy to miss inspection, complex assembly and operation, inconvenient to carry and transport, low efficiency and other problems.a82744dba8c13f051779fe73845c5d7.jpg
