Perceptive dental robots are centered on the core goals of "high precision, rapid restoration, and AI-assisted diagnosis and treatment," focusing on complex scenarios in the oral cavity such as low light, narrow spaces, dynamic movements (patient movement), and multiple fluids (saliva, mouthwash). Their imaging systems must meet the key requirements of "strong penetrability, precise details, and adaptation to compact structures." The endoscope camera module equipped with the OmniVision OV02C10 sensor provides core imaging support for dental robots through its precise matching of parameters and performance. The specific advantages can be analyzed from the following dimensions:
The oral cavity has issues such as low light, large light-dark contrast (reflection on tooth surfaces and dark areas of gums), and fluid interference (saliva, treatment fluids), which directly affect imaging clarity and diagnostic accuracy. The core technology combination of this module specifically addresses this pain point: On one hand, the Nyxel™ near-infrared technology achieves a quantum efficiency of 60% at 850nm wavelength and 40% at 940nm wavelength. Combined with the high light-sensing capability of the 2.9μm×2.9μm large pixel size, it can penetrate oral fluids and superficial gum tissues to clearly capture details on tooth surfaces and subgingival areas (such as early caries and tooth enamel cracks), which highly aligns with Perceptive dental robots’ requirement of "imaging through the gingival margin and fluids." On the other hand, the HDR technology with a 120dB dynamic range effectively balances the light-shadow difference between tooth reflections and dark oral areas, avoiding detail loss caused by overexposure or underexposure. Additionally, the 6 integrated 9653 LED beads in the lens can flexibly supplement light in low-light environments, further improving imaging stability and providing a high-quality 3D data foundation for AI diagnosis.
The internal space of the oral cavity is narrow (limited distance between the upper and lower jaws), and the manipulator of dental robots must balance flexibility and compactness, placing strict requirements on the size and structural design of the imaging module. With a lens diameter of only 3.9mm and a compact 1/7.25-inch sensor, this module can be easily integrated into the end of the robot’s slender manipulator without interfering with core operations such as tooth preparation and restoration placement. At the same time, the 120° field of view and 2.78mm maximum imaging circle can cover the observation range from a single tooth to a local dentition, allowing comprehensive visual field acquisition without frequent lens position adjustments. Furthermore, the module adopts a Separated design, transmitting MIPI signals to the robot’s DSP board via a Type-C interface. Combined with USB 2.0 speed and UVC protocol, it enables plug-and-play efficient integration without complex secondary development, perfectly aligning with the design logic of dental robots for "compact structure + simplified integration."
The core advantages of Perceptive dental robots lie in "15-minute rapid crown restoration" and "100-micron-level operation precision," which require the imaging system to not only provide high-definition details but also adapt to AI-assisted diagnosis and treatment planning. The module features 2MP pixels and 1080P resolution, which can clearly present tiny details such as tooth enamel texture, caries boundaries, and pulp chamber positions. It provides precise image data for AI algorithms in caries segmentation and restoration geometric simulation, helping to improve diagnostic accuracy (aligning with Perceptive’s stated goals of "early diagnosis and high accuracy"). Meanwhile, the manual focusing function can accurately lock onto specific observation areas (such as interproximal caries and tooth preparation margins), avoiding the omission of tiny targets by auto-focus and ensuring the visual guidance precision of the robot in high-precision operations such as tooth grinding and restoration fitting. In addition, the 60FPS high frame rate can effectively reduce motion artifacts caused by slight patient movements (such as masticatory muscle contraction and slight head movement), ensuring imaging stability and providing real-time feedback for the robot to dynamically adjust its operation path.
Dental medical equipment must comply with medical safety and environmental standards in various regions worldwide and must have stability for long-term high-frequency use. This module has passed multiple authoritative tests and certifications such as FCC, CE, Reach, and RoHS, fully meeting the medical compliance requirements of dental robots and avoiding product launch delays due to compliance issues. At the same time, the module is manufactured using SMT process and Active Alignment (AA) process, ensuring the assembly precision of the lens and sensor as well as imaging consistency. It can cope with high-frequency startup and frequent movement scenarios in the daily diagnosis and treatment of dental robots, reducing equipment operation and maintenance costs. Furthermore, the 940nm near-infrared light is invisible, causing no irritation to patients’ eyes, and it does not rely on ionizing radiation such as X-rays. This complements the safety advantage of Perceptive dental robots of "no ionizing radiation," further enhancing the safety of diagnosis and treatment.
In summary, this endoscope camera module is not merely an imaging component. Through multi-dimensional empowerment including "low-light/fluid-penetrating imaging, narrow-space adaptation, high-definition precision support, dynamic stability feedback, and compliance and reliability assurance," it accurately matches the core needs of Perceptive dental robots. Its application not only improves the imaging quality and operation precision of dental robots but also simplifies the system integration process and reduces compliance risks. It provides key hardware support for "rapid, accurate, and safe" dental restoration diagnosis and treatment, helping dental robots achieve the transformation from prototype to clinical application.
