Triple Lens AI Depth Sensor Offers Advanced Object Recognition
Kyocera Corporation has developed a Triple Lens AI-Based High-Resolution Depth Sensor for close imaging. The camera utilizes three lenses and proprietary AI to recognize semi-transparent, thin, and fine line-shaped objects that were previously difficult to detect with the human eye and traditional stereo cameras. The new Triple Lens AI-Based Depth Sensor accurately measures the distance to and size of such objects with more precision than ever before, tripling its precision measurement of tiny objects from 1 mm to 0.3 mm. The triple lens is expected to help with inspection processes in manufacturing.
The triple lens configuration enables precise measurements, including distance and size, of thin, linear objects positioned parallel to the direction between the left and right lenses. This capability allows the measurement of ultra-fine wires and different objects, such as:
- Thin, irregularly shaped linear objects, such as harnesses or ultra-fine wires
- Reflective objects like metal
- Translucent objects like plastic
Labor shortages can be a challenge in many countries, particularly developed nations, driving the need for further productivity improvements to compensate. As one solution, advanced vision sensing technology capable of object recognition as a substitute for the human eye is gaining attention.
In 2024, Kyocera developed a Dual Lens AI-Based High-Resolution Depth Sensor for Close Imaging capable of high-precision distance measurement with 100μm resolution at a 10cm range, allowing distance measurement of tiny objects around 1mm in size, even from reflective or semi-transparent objects, which was difficult for conventional stereo cameras.
However, distance measurement with a dual lens sensor can be challenging for objects with limited surface features or in environments where part of the object is obscured, preventing full recognition. Kyocera’s new Triple Lens AI-Based Depth Sensor was created to solve these challenges.
Kyocera’s new Triple Lens AI-Based Depth Sensor acquires three sets of parallax information—’left-center’, ‘center-right’, and ‘left-right’ – from a close distance of 10 cm through the combination of three lenses and proprietary AI. Combining multiple parallax data sets virtually eliminates mismatches and reduces blind spots, significantly improving measurement reliability. It also enables accurate distance measurement for objects that were difficult to measure with a single lens, specifically those with repetitive patterns, partially reflective metals, translucent plastics, and other surfaces lacking distinct features. Kyocera’s new AI-Based Depth Sensor can accurately measure distances to thin, irregularly shaped linear objects and ultra-fine wires with diameters as small as 0.3mm.
The technology will be exhibited CES 2026, held in Las Vegas, Nevada, USA, January 6 – 9, 2026.
