3D Line Laser Sensor

Description

“3D Line Laser Sensor | High-Precision Micron-Level Measurement for High-Speed Online Profiling and Weld Inspection”

By using an image sensor to capture the laser line projected onto the surface of an object in real time, the system extracts the precise contour positions from the image. Through analysis of these contour positions, it derives the X- and Z-axis position data for each individual contour, whilst simultaneously capturing and recording the reflected brightness data at the corresponding positions. By utilising the relative motion between the object under test and the sensor, the system acquires and fuses a series of contour data points, ultimately outputting a depth map with sub-micrometre precision and a clear, sharp brightness map.
This core data constitutes the key information driving industrial vision for inspection, recognition, positioning and guidance!
It is particularly suitable for applications involving the detection and measurement of Z-axis height information, such as the measurement of product height differences, flatness, positional accuracy, contour accuracy and volume. As it is minimally affected by ambient light, it is widely used in the field of industrial inspection within smart manufacturing.

Dimensional inspection, appearance inspection, shape inspection
Resistant to the effects of colour and ambient light; simultaneously captures reflected luminance information
Not only can it detect height, width, area and volume,
but it can also perform geometric dimensional inspection and measurement
based on point, line and surface features
Utilising a single-wavelength line laser light source and
capturing 3D information via height sensing, it can reliably and clearly
detect height differences in objects of the same or different colours, whilst being largely unaffected by ambient light
By collecting reflected brightness information, it generates
clear and sharp brightness maps suitable for 2D
inspection, with height and brightness data corresponding at the pixel level
Applications of line laser 3D inspection:
Height, volume, presence/absence
Width, foreign objects, angle
Depth, burrs, orientation (front/back)
Thickness, cracks, warping
Height differences, dents, lifting
Flatness, defects, counting
