Hikrobot unveils 3D Laser Profile Sensor for Indian manufacturing sector

Hikrobot has launched its 3D Laser Profile Sensor in India, a move expected to give a significant boost to the country’s consumer electronics, lithium battery, and PCB manufacturing industries.

The new sensor leverages laser triangulation technology to deliver micrometre-level precision, enabling non-contact, high-speed, and high-accuracy 3D measurement. Designed for real-time industrial inspection, it can output high-frame-rate point clouds, depth images, and intensity images with exceptional clarity and speed.

Advancing high-precision, non-contact measurement

The 3D Laser Profile Sensor employs 405 nm ultra-uniform fine blue light to capture contour lines of measured objects with remarkable accuracy. A custom large-iris lens ensures superior MTF resolution, while a high dynamic range sensor and Scheimpflug optical design deliver clear imaging even in complex industrial environments.

Equipped with a built-in high-speed computing module, the system reaches processing speeds of up to 19 KHz/s, ensuring seamless operation for demanding production lines. Its high-speed image acquisition module uses diffuse reflection to collect data, reconstructing the 3D contour and spatial information of the object in real time.

The high-speed image acquisition chip supports large pixel size and wide dynamic range, achieving frame rates up to 49K Hz through SOC hardware acceleration.

A combination of centre point extraction and subpixel super-resolution algorithms further enhances measurement accuracy, achieving precision down to 0.05 pixels.

Robust optical performance in complex conditions

To handle varied lighting conditions, the sensor supports multi-exposure fusion, retaining valid grayscale data across different exposures. Its single-frame HDR technology allows accurate reconstruction of scenes with mixed reflectivity, ensuring consistency under high-speed scanning.

Advanced halo feature extraction helps filter stray light, improving accuracy and reliability in centre point detection.

The device also includes built-in post-processing algorithms such as spatial and time-domain filtering — optimising performance without relying on external CPU resources.
