LMI Technologies Adds New Model to Its Series of 5-Megapixel 3D Snapshot Sensors

The Gocator® 3520 extends the field of view of LMI's 5-megapixel smart snapshot sensor series for metrology-grade inline measurement and inspection with increased scan coverage

Gocator 3D Snaphot Sensor - High XY Resolution with Extended Field of View

LMI Technologies (LMI), the global leader in 3D scanning and inspection, is pleased to announce the official launch of the Gocator 3520 smart 3D snapshot sensor. The latest addition to its industry-leading series of 5-megapixel 3D snapshot sensors, the Gocator® 3520 introduces an expanded field of view with the same high XY resolutions, short exposure times, and fast data acquisition rates required to achieve metrology-grade inline quality inspection. 

The 3520 continues to grow the types of applications customers can solve with LMI’s stereo 3D snapshot sensor technology, including robot-driven quality control and inspection of larger objects with start stop/go motion in inline production systems.

The Gocator 3520 sensor is ideal for customers who need to perform:

  • Scanning and inspection of machined parts such as automotive powertrain (engine and transmission), body-in-white, wheels (lug nut location)
  • Robot-mounted inspection applications that require stitching of multiple scans to generate complete 360-degree models of larger parts and assemblies for surface measurement and inspection
  • Robot-mounted applications where the sensor provides XYZ coordinates to the robot for precision pick-and-place (e.g., structured/semi-structured bin picking)
  • ​General factory automation applications that require large fields of view and high-density 3D point cloud generation


The sensor’s larger field of view and shorter clearance distance allow users to minimize the travel distances of the robot arm, increasing overall inspection coverage as a result. This design also offers a greater range of robot movement to support various scan angles.

High-Intensity LED Projector and Stereo Camera Design

Gocator 3520’s high-intensity LED projector delivers the short exposure times and fast scan rates required to generate high-quality scans with minimal motion blur caused by target vibration or movement jitter. The sensor’s 5-megapixel stereo camera design maximizes data capture by triangulating three ways to minimize occlusion.

The Gocator 3520 is a new addition to our 5Mp stereo snapshot series that expands the field of view while maintaining high XY resolution and leveraging brighter projector output. This combination delivers smart 3D inspection into many new applications including robot-driven quality control and stop-and-go part verification,” said Terry Arden, CEO, LMI Technologies.

And like all Gocator 3D smart sensors, the 3520 doesn’t require an external controller or PC. Built-in 3D inspection software allows for out-of-the-box measurement and seamless integration with existing systems. By installing the sensor on a robot arm, customers can perform built-in hand-to-eye calibration between robot and sensor to easily achieve smart robot inspection leading to a path of greater factory automation.
