The newspaper reported that the facial recognition system will be used on 300,000 to 400,000 people, including athletes, service personnel, security staff and journalists. If they are given a pass into Olympic facilities in advance, computers will automatically recognize their faces using cameras.
It is expected that this will also prevent malicious individuals from illegally entering facilities using stolen passes.
Tokyo plans to host the Olympic Games from July 24 to August 9, 2020. It is reported that about 40 facilities at the 2020 Tokyo Olympics and Paralympics will install this system, on the one hand as a measure to strengthen anti-terrorism security, and on the other hand to simplify the procedures for passing checkpoints.
The world's first "submersible photography" drone is launched: it can capture underwater scenery
According to Singapore's "Lianhe Zaobao" report on December 25, French free diving master Guillaume Nery ) recently dived into the waters off the coast of Nice in southern France. With the help of the "submersible photography" drone "iBubble", he could easily capture the surrounding underwater scenery without using any hands.
This is the world’s first civilian drone designed specifically for underwater photography. It was developed by a French start-up company and is currently only a prototype. Its target users are diving enthusiasts, scientists, resorts and diving centers. wait. It is equipped with seven engines, four propellers, a yellow casing, a camera lens and lights, and can automatically follow the user and take pictures.
AR optical technology company Lingxi Micro-Light announced that it has obtained tens of millions of Series A financing from Sequoia China
On the 25th, AR optical display technology provider Lingxi Micro-Light announced that it has obtained and completed the financing of Shan Capital China Fund raised tens of millions of yuan in Series A financing.
Lingxi Micro-Light was established at the end of 2014. Different from the strategy of technology giants in laying out the entire AR industry chain, Lingxi focuses on the bottleneck technology of AR equipment - optical display technology, focusing on the core device optical engine in AR products. .
In the view of founder and CEO Zheng Yu, optical display is the most important missing piece of the AR industry chain.
Optical display is the most difficult core component in AR equipment and the most affecting user experience. Because it is thick and opaque, AR devices have been difficult to meet consumer demand. Both international giants and start-up companies seem to be waiting for an optical solution suitable for consumer-grade AR products to release the "first-generation iPhone" in the industry.
Zheng Yu, founder and CEO of Lingxi Micro-Light, said: Optical waveguide technology is the foundation and core of consumer-grade AR display technology. After overcoming multiple technical problems, the new generation of products we are about to release will meet the needs of the first generation of consumer AR products in terms of cost, size and display effect. In the future, the combination of optical waveguides and micro-electromechanical systems can further improve the AR display effect. Digital light field technology based on optical waveguides can also solve the problem of visual vergence accommodation conflict (VAC). These are technological breakthroughs we are focusing on.
Lingxi’s core R&D team mainly comes from the top optical laboratories of Peking University and Tsinghua University, and has a process team with an average of more than 20 years of industrial experience. After the A round, the company plans to use funds mainly for cutting-edge technology research and development, product iteration optimization, and preparation of its own production lines. At the same time, it will also invest more in the introduction and training of professional talents.
