Industrial machine-vision maker Hikrobot has rolled out its DP Series of 3D laser profilers, a line of non-contact sensors aimed at giving manufacturers finer control over quality checks on fast-moving production lines. The sensors use laser triangulation to build micrometre-level 3D point clouds, depth maps and surface profiles in real time — and, according to the company, are already in use across electronics, EV battery, automotive and PCB manufacturing operations, including in India’s expanding electronics and EV supply chains.

A notable design choice is where the processing happens: the sensors carry their own edge-computing hardware, so measurement data is crunched on the device itself rather than routed through a host PC’s CPU. Hikrobot says this lets the DP Series hit scan speeds of up to 49 kHz without adding load to a factory’s existing computing infrastructure — a detail likely to matter to plant engineers weighing sensor upgrades against limited compute budgets.

A Tiered Product Line

The DP Series is split into four tiers, each apparently targeting a different point on the cost-versus-precision curve. The DP2000 series is positioned as the standard workhorse, offering 3,200 profile points, scan rates up to 23.9 kHz and IP67 protection; its MV-DP2240-01P model, for instance, is rated for Z-axis resolution down to 6.47 micrometres. The DP3000 series sits above it, promising higher scan rates (up to 46.7 kHz), stronger light sensitivity and what Hikrobot describes as 95% laser uniformity with ultra-low noise. At the top, the DP4000 series is billed as the flagship, pairing a 2000×2000 sensor array with telecentric optics and scan speeds up to 49 kHz. A separate Binocular Single-Line series uses two cameras with a single laser projector, intended to capture blind spots and complex geometry that a single-camera setup might miss.

Technical Details Worth Noting

Several of the underlying techniques point to problems that commonly trip up laser-based inspection systems. Sub-pixel center extraction — tracking the laser line’s reflection to a claimed accuracy of 0.05 pixels — is meant to sharpen measurement precision at the hardware level. Stray-light halo filtering targets the optical noise that shows up when scanning reflective, metallic or wet surfaces, a known weak point for triangulation sensors. A single-frame HDR mode is designed to handle parts that mix highly reflective and deep matte-black materials in one pass, while a multi-camera stitching feature lets several sensors merge their views into one unified point cloud for larger objects. Spatial filtering, time-domain filtering and empty-point interpolation are all handled on-device as built-in post-processing.

Where the Sensors Are Being Used

Hikrobot points to three main application areas. In lithium-battery production, the sensors are used to inspect blue-film battery surfaces for air bubbles and droplets, and to detect dents on soft-pack batteries. In consumer electronics assembly, they’re applied to Z-axis height checks, coplanarity testing and gap/flush measurements. And in automotive parts manufacturing, the company cites use cases spanning black rubber seals, welding seams, safety-belt weave inspection and detection of micro-scratches on metallic casings — all areas where manual or camera-only inspection can struggle to catch defects reliably at line speed.

The launch adds to Hikvision India’s broader push beyond its core security business into industrial automation and robotics, part of a stated expansion strategy that also touches smart-home products. The company manufactures a range of video security products locally near Mumbai under the ‘Make in India’ framework, and has said it intends to back the new sensor line with technical support through its existing pan-India branch network.
