Recently, Hikrobot launched the 3D Laser Profile Sensor in India for a variety of use cases. It is anticipated to significantly boost the PCB, lithium battery, and consumer electronics manufacturing ecosystem. The state-of-the-art 3D Laser Profile Sensor from Hikrobot is intended for high-precision, non-contact measurement applications.
The 3D laser profile sensor can produce high-frame point clouds, depth images, and intensity images at the micrometer level in real time based on laser triangulation measurement.
It is widely relevant to high-precision, non-contact online 3D measurement scenarios in the PCB, lithium battery, and consumer electronics industries.Â
Real-time output of high-precision point cloud data
The laser profile sensor precisely extracts the contour line of the observed object using ultra-uniform fine blue light at 405 nm. Extremely high MTF resolution is guaranteed by the specially designed large-iris lens.
In addition, it works flawlessly with a high dynamic range sensor and unique Scheimpflug optical design to provide clear imaging throughout the whole range in incredibly complicated situations.
With its high-speed processing unit, the camera’s integrated computing design allows for a maximum processing speed of 19 KHz/s. The high-speed image capture module gathers the laser line on the surface of the measured item with diffuse reflection using the triangulation concept.
The three-dimensional contour data of the measured object’s surface is computed using the high-precision image processing algorithm integrated into the hardware. The relative movement between the camera and the measured object is then used to restore the three-dimensional spatial information of the target object.
Large pixel size, high frame rate, and broad dynamic range are characteristics of the high-speed image acquisition chip. The camera can reach a maximum frame rate of up to 49K Hz thanks to hardware acceleration provided by the SOC processor.
The extraction accuracy is increased to 0.05 pixels by combining the center point extraction approach with the subpixel super-resolution processing algorithm.
- Multi-exposure fusion: Retain the valid grayscale information under different exposures, applicable to scenes with both high and low reflections.
- Single-frame HDR: Achieve high-precision reconstruction of complex reflectivity scenes under high-speed scanning.
By extracting the halo features, different optical signals are filtered to suppress the influence of stray light halo on center point extraction.
Adopts built-in rich post-processing algorithms, including spatial filtering and time domain filtering, convenient for users to choose, without occupying the host CPU resources.
