With the rapid advancement of machine vision, artificial intelligence, and human-computer interaction technologies, the concept of high-intelligence robots, once confined to the realm of science fiction, is now becoming increasingly tangible. Consumer-grade robots are slowly making their way into our homes and stores, helping us handle various physical tasks. However, in recent times, some netizens have expressed frustration over the seemingly "mentally challenged" behavior of their robotic vacuum cleaners. This has sparked extensive discussions among the public regarding the current state of robotic applications.

While it’s amusing, it also highlights a pressing issue—when robots malfunction due to technical hiccups, it not only frustrates users but also poses a significant challenge for manufacturers. Such incidents can lead to costly product recalls, necessitate production line adjustments, and severely damage brand trust. Consumers’ faith in these products can quickly erode, making it crucial for companies to focus on enhancing their product reliability.
Despite these challenges, the widespread interest from both the public and media has underscored the immense potential of the robotics market. For companies operating in this space, adopting cutting-edge machine vision technologies to enhance product functionality and user experience has become a necessity. In the robotics sector, the current standard for intelligent recognition relies heavily on 2D image processing through sophisticated algorithms. However, since 2D images inherently lack depth and comprehensive spatial data, even the most advanced algorithms face limitations. This is where the integration of 3D imaging technologies proves invaluable, offering richer spatial information that allows for more accurate object recognition, navigation, and tracking.
One promising approach involves leveraging 3D depth cameras as part of machine vision systems. These cameras enable functionalities like Simultaneous Localization and Mapping (SLAM), obstacle avoidance, target tracking, human-computer interaction, and automated object manipulation—all while balancing cost considerations. This combination of affordability and effectiveness has earned 3D depth cameras recognition within the industry as a practical and cost-efficient solution.
Currently, there are three primary types of 3D depth camera technologies:
1) **Structured Light**: This technique projects a pattern of light onto an object's surface, capturing how the light interacts with the object to determine its position and depth. By analyzing the deformation of the projected pattern, the system reconstructs the object's 3D structure.
2) **Time-of-Flight (ToF)**: ToF sensors measure the time it takes for infrared light to travel from the emitter to the object and back, calculating the distance based on this time difference.
3) **Stereo Vision Systems**: These use two cameras to simulate human binocular vision, calculating depth based on the disparity between the images captured by each camera.
As shown in the diagram below, structured light stands out due to its technological maturity, ability to produce high-resolution depth maps, and relatively low hardware costs. Compared to other 3D camera technologies, it requires less complex algorithm development. Moreover, ongoing advancements, such as improvements in anti-interference capabilities, continue to bolster its appeal.
International tech giants like Apple, Microsoft, and Intel have already embraced structured light technology in their products, signaling confidence in its long-term viability. Despite setbacks, such as PromeSense losing its license from Apple and Intel RealSense products being prohibitively expensive, one domestic company has emerged as a leader in delivering affordable, mass-produced structured light solutions. Their Astra series of 3D depth cameras—including models like Astra, Astra Pro, and Astra Mini—can perform SLAM mapping, enable obstacle avoidance, track moving objects, facilitate human-computer interactions, and automate object grasping.

The Astra series depth cameras consist of an infrared camera, a laser, and an RGB camera. The module measures 165mm x 38mm x 30mm, with a detection range of 0.6 to 8 meters and an accuracy of ±1mm to ±3mm. The field of view spans 58.4 degrees, with a maximum resolution of 1280x1024@7FPS. The Astra Mini is even more compact, measuring 80mm x 20mm x 19.3mm, with identical detection parameters but better portability for diverse applications.
What truly sets the Astra series apart is its proprietary 3D computing chip, depth algorithms, and system support SDK—all developed in-house. Since its founding, the company has filed nearly 300 patents. Its R&D team boasts expertise spanning底层芯片ã€æ·±åº¦ç®—法ã€ç³»ç»Ÿæž¶æž„以åŠä¸Šå±‚应用, enabling them to offer consumer-grade solutions at significantly lower costs than those offered by foreign competitors.
Looking ahead, Obi Vision is set to release a next-generation structured light 3D sensor camera with enhanced compactness, superior resolution, and reduced power consumption. These improvements make it ideal for integration into robots, smartphones, tablets, laptops, and other small devices requiring 3D vision capabilities. This launch is expected to revolutionize the design of smart terminals and create substantial ripple effects across industries.
Obi Vision’s commitment to advancing structured light 3D sensing technology has already seen applications in areas like gesture-controlled TVs, robotics, and security systems. As a pioneer in integrating hardware and software technologies, Obi Vision aims to empower every terminal device to "see" and understand the world around it.
