The Gemini 435Le is a high-performance industrial-grade binocular 3D camera launched by Orbbec. Utilizing a master-slave fusion stereo vision technique, it consistently delivers high-quality depth images in both indoor and outdoor scenarios, ensuring reliable operation for robots in complex and demanding environments.

Its core strengths are primarily reflected in three aspects:

• Long-Range, High-Precision Perception: Comprehensively optimized for depth performance, it provides low-noise, high-density, and high-integrity environmental depth data during movement. It particularly enhances depth effectiveness at long distances, aiding large equipment in stable navigation and precise obstacle avoidance within complex environments.
• Accurate Edge Restoration Capability: Accurately restores the contour edges of complex objects. It can effectively identify objects made of various materials such as plastic, wood, and metal, meeting the requirements of high-precision identification and measurement tasks.
• Flexible Multi-Scenario Adaptation: Features multiple built-in preset depth modes. Users can flexibly switch between them via software (e.g., AMR perception mode for obstacle avoidance, dimension measurement mode for identification). A single camera can handle multiple tasks, significantly reducing hardware costs and system integration complexity.

Furthermore, the Gemini 435Le boasts an IP67 protection rating, exhibits excellent electromagnetic interference resistance, and can operate in a wide temperature range from -10°C to 50°C, ensuring stable performance even under harsh industrial conditions.
