What is the experience of using face recognition system and the world's first "sneak shot" drone?

The newspaper reported that the face recognition system will be used for 300,000 to 400,000 people, including athletes, service personnel, security department staff and journalists. If they are given a pass to enter the Olympic facilities in advance, the computer will automatically recognize their faces with the help of the camera.

It is expected that this will also prevent malicious elements who steal other people's passes from illegally entering the facility.

Tokyo plans to host the Olympic Games from July 24th to August 9th, 2020. It is reported that the system will be installed in about 40 facilities of the 2020 Tokyo Olympic and Paralympic Games, on the one hand, as a measure to strengthen anti-terrorism security, and on the other hand, to simplify the procedures for passing through checkpoints.

The world's first "sneak shot" drone came out: it can capture underwater scenery.

According to Singapore's Lianhe Zaobao (65438+February 25th), Guillaume Nery, a French master of free diving, recently dived into the sea off the coast of Nice in southern France, and with the help of the "submersible" drone "iBubble", he could easily capture the surrounding underwater scenery without hands.

This is the world's first civilian drone specially designed for underwater photography. It was developed by a French startup and is still a prototype. Its target users are diving enthusiasts, scientists, resorts and diving centers. It is equipped with seven engines, four propellers, a yellow shell, a camera lens and a lighting lamp, which can automatically follow the user and shoot.

AR Optical Technology Company Lingxi Microlight announced that it has obtained Sequoia China100000000000000000 A round of financing.

On 25th, Lingxi Microlight, a provider of AR optical display technology, announced that it had obtained and completed tens of millions of RMB Series A financing from Sequoia Capital China.

Linxi twilight was established at the end of 20 14. Different from the strategy of technology giants to lay out the whole industrial chain of AR, Linxi focuses on the bottleneck technology of AR equipment-optical display technology, focusing on the optical engine, the core device in AR products.

JUNG WOO, founder and CEO, said that optical display is the most important puzzle in the augmented reality industry chain.

Optical display is the most difficult and influential core device in AR equipment. Because it is thick and opaque, AR equipment is difficult to meet the needs of consumers. Both international giants and startups seem to be waiting for an optical solution suitable for consumer-grade AR products to release the "first generation iPhone" in the industry.

JUNG WOO, CEO of Lingxi LLL, said: Optical waveguide technology is the foundation and core of consumer-grade AR display technology. After overcoming many technical problems, the next generation of products we will release soon will meet the needs of the first generation of consumer-grade AR products in terms of cost, volume and display effect. In the future, the combination of optical waveguide and MEMS can further improve the AR display effect, and the digital light field technology based on optical waveguide can also solve the problem of visual convergence adjustment conflict (VAC). These are the technological breakthroughs we are concerned about.

Linxi's core R&D team mainly comes from the top optical laboratories in Peking University and Tsinghua, with an average of more than 20 years of industry experience. After Round A, the company plans to use the funds mainly for cutting-edge technology research and development, product iterative optimization and preparation of its own production line. At the same time, we will also invest more in the introduction and training of professionals.
