background knowledge

In the field of modern medicine, the accuracy of medical instruments plays a crucial role in disease diagnosis, surgical treatment and medical research. From microscopic cell detection instruments to macroscopic surgical navigation and positioning devices, any slight error can lead to serious consequences.

With the continuous progress of science and technology, the emergence of 3D camera technology has brought a new solution for medical instrument testing. It can comprehensively test medical instruments in a non-contact, high precision and fast way, greatly improving the quality and safety level of medical care.

Camera selection

Today we will introduce the application case of Next vision tech LVM2 346 line laser 3D camera in medical industry testing!

The LVM2 3463D intelligent sensor of Next vision tech has a full-frame acquisition rate of 1000Hz, physical contour points of 1920 points, and can achieve up to 4096 points under uniform spacing sampling conditions for depth maps, specifically designed to meet the harsh production environment in factories, suitable for scenarios requiring rapid detection of moving objects.
