The China International Welfare Expo and China International Rehabilitation Expo (CR EXPO) were held last week at the National Convention Center in Beijing.
At the first launch event of innovative assistive device products, China Mobile's Body Intelligent Industry Innovation Center released the "Lingxi" electronic guide dog body intelligent product.
The China Mobile Intelligent Industry Innovation Center stated that by 2025, the number of visually impaired people in China has reached 17.31 million. They long to step out of their homes and measure the world with their footsteps. The limited obstacle avoidance ability of traditional canes, the high cultivation cost and low coverage of biological guide dogs, all seriously restrict the smooth travel of visually impaired groups. Since the implementation of the technology assisted disability policy in 2017, the demand for intelligent services for the visually impaired has continued to rise, and there is an urgent need to solve their living and travel difficulties through technological innovation.
The China Mobile Intelligent Industry Innovation Center focuses on the five core needs of visually impaired people, including autonomous navigation, obstacle avoidance, effective guidance, visual assistance, and efficient communication, to create the "Lingxi" electronic guide dog. The highlights are as follows:
The "Lingxi" electronic guide dog uses the fusion technology of LiDAR point cloud and visual monocular 3D reconstruction to obtain real-time latitude and longitude information and construct high-precision maps. The map supports stitching and large complex indoor and outdoor spaces, with a mapping accuracy of centimeter level.
Based on high-precision maps, the "Lingxi" electronic guide dog has an active navigation and obstacle avoidance system, with the core capabilities of optimal path planning, multi-sensor fusion obstacle avoidance, and adaptive complex terrain. It can detect dynamic obstacles in real time and achieve flexible obstacle avoidance.
The "Lingxi" electronic guide dog carries a guide cane for physical guidance feedback, and obtains all movement intentions such as turning, acceleration, deceleration, and stopping of the guide dog through non delayed physical force; Equipping visually impaired individuals with bone conduction Bluetooth earphones to receive real-time feedback from robotic dogs does not affect environmental sound listening. In addition, guide dogs will briefly summarize information and broadcast it at the most suitable pace for the user.
The visual recognition ability of the "Lingxi" electronic guide dog can recognize specific objects and text, supporting a large number of general life service scenarios such as supermarkets and stations; Built in China Mobile's "Nine Days" large model, allowing the "Lingxi" electronic guide dog to carry natural language dialogue capabilities.
