The expanding role of 3D cameras in industrial quality control

October 2025 Sensors & Transducers

Across factory floors, warehouses, mines and research centres worldwide, computer vision paired with 3D camera technology is revolutionising quality control. This powerful combination transforms inspections from reactive checks into proactive safeguards that catch defects early and ensure consistent product excellence.

“A lot of quality control still depends on human judgement,” says Dylan Naidu, business development engineer at TANDM South Africa, the official distributor of Basler’s 2D and 3D industrial cameras. “Humans can miss subtle details, and this is where computer vision and 3D cameras fill that gap with precise, consistent, real-time insights that drastically reduce errors.”

Basler’s latest 3D stereo cameras, combined with AI-powered image processing introduced this year, push defect detection even further. The AI accelerates identification while cutting false positives by distinguishing real issues from acceptable variations. The AI integration is a game changer, delivering faster, more accurate results, which in turn means less waste, downtime and recalls, and greater confidence in every product shipped.

While 2D cameras capture flat images effective for many tasks, they fall short in detecting subtle defects or depth variations. Three-dimensional technology adds a crucial layer of depth perception, spotting irregularities invisible to 2D systems.

“Catching defects early is critical. Errors in production cost millions; a faulty automotive part can trigger recalls and damage brand reputation, while food contamination risks fines and lost consumer trust. Real-time detection before products leave the factory reduces risk and expense dramatically,” adds Naidu.

This sort of quality control is essential across every production line, even in sectors like the fruit industry, where even if the smallest critical defect is a one-centimetre bruise or bite mark, you still need the right resolution, colour fidelity and shutter speed of a 2D camera to catch it. A 3D stereo camera plays a complementary role by measuring contour and depth to assist with size sorting, ensuring fruit meets exact grading standards before it leaves the line.

At the core of Basler’s innovation is computer vision that enables instant, precise image capture and interpretation. The company’s broad product range covers everything from high-precision monochrome cameras for fine contrast detection to ultra-fast colour models for complex inspections. Customisable lenses, lighting and mounts allow engineers to tailor solutions perfectly to their needs. The real strength is the seamless integration of advanced cameras, adaptable accessories and intelligent AI software. “Whether you need rapid colour analysis, high-speed video or accurate depth mapping, this synergy makes industrial automation smarter, faster and more reliable,” says Naidu.

Five sectors where computer vision and 3D cameras are making the biggest impact are:

Food and beverage: Quality control in food production requires stringent safety and regulatory requirements. Basler cameras can inspect products for size, colour and surface defects at high speed, ensuring compliance before goods are packaged and shipped. This reduces product recalls and protects consumer safety.

Automotive manufacturing: From checking paint finish uniformity to detecting microscopic leaks in engines, both Basler 2D and 3D cameras can help manufacturers identify faults before a vehicle reaches the customer, like spotting micro leaks during engine testing. Fixing these at the factory saves millions in recall costs and protects brand integrity.

Mining and heavy industry: In mining operations, safety is paramount. Machine vision systems can monitor conveyor belts, detect irregularities in material size and ensure proper safety compliance such as verifying helmet use, without slowing operations. This automation reduces human error and improves onsite safety outcomes.

Warehousing and logistics: In large-scale distribution centres, Basler’s 3D cameras can measure package dimensions instantly, optimise storage allocation and verify barcodes for order accuracy. This reduces labour requirements, speeds up fulfilment and prevents costly shipping errors.

Research and development: Universities and research institutes use Basler cameras for applications like hazard detection, digital image correlation and automation testing. From simulating autonomous vehicle responses to monitoring complex manufacturing processes, both 2D and 3D cameras are valuable tools for innovation, with the choice depending on the specific application.
