The first Tango development contest in China, a foot three-dimensional measurement app won the championship

On October 12, 2016, the National Public Entrepreneurial Venture Innovation Week (Doublebreak Week) opened on schedule, and the Tango Maker Marathon Software Development Contest (Hackathon) hosted by Lenovo Accelerator also welcomed in the Shenzhen branch of the Double Innovation Week. The final day of the game came.

Lei Feng network learned that a total of 19 creators team passed the preliminary screening of the organizing committee to qualify for the competition. They have different backgrounds. Among them are entrepreneurs from Silicon Valley, engineers from the Netherlands, designers from Taiwan, and many domestic employees. In addition, they have designed a wide range of products, for the education industry, tourism industry and home improvement industry, but also the most simple and rough AR games.

The specific rules of the game are as follows:

First of all, all works must be based on the Lenovo Phab2 Pro phone.

In addition, there are strict restrictions on time. The competition lasted 4 days and 3 nights, and the plan to start a half-day start-up ceremony and the last day of the match day left the team actually able to use the development time of less than 72 hours. Regardless of whether they are finally formed or not, they all need to submit their works before the match day, and then conduct the morning half-day preliminary match and the half-day final match.

Finally, the appraisers will score 4 points in terms of innovation, commercialization, technology and team integration, and select 1 first prize, 2 second prizes and 3 third prizes. The first team will receive Lenovo Accelerator Free Acceleration Services and up to 1 million yuan in investment in seed ventures. At the same time, the final work will also have the opportunity to launch the Lenovo Phab2 Pro mobile phone.

After a fierce competition, the Bigfoot team finally came to the fore and they won the championship with a large amount of App, Bigfoot, which measured the accurate foot data through 3D modeling. After the match, they accepted an interview with Lei Fengnet (searching for "Lei Feng Net" public concern) .

It is understood that the "Bigfoot" team has two members. The team leader Yu Xiaodong is responsible for the processing after data collection, and another member Liu Dian is responsible for the foot data collection based on Tango technology. Both are from a company named Cloud Technology's startups are similar to most of the participating teams. They also hope to join the Lenovo Accelerator through this competition and get backing resources from Lenovo Group.

Yu Xiaodong introduced that this full-size App is easy to use. It only needs to open the mobile phone application and use Tango's unique motion tracking camera and infrared depth perception technology to perform 3D scanning of the foot and modeling, and then through the calculation of the cloud server. Can get detailed foot information. However, it is still in the Demo stage. There are still many places that need further optimization and improvement.

According to Xiaodong, the original intention of designing this product was that the demand for customization from consumers and enterprises gradually increased.

The overall development trend of the commodity economy in the future will most likely be Customer 2 Manufacture. For personalization and uniqueness, people will increasingly tend to customize products directly to manufacturers rather than standardizing operations in the assembly line. Therefore, manufacturers have always been trying to upgrade.

The Bigfoot app is based on a customized data acquisition application developed by Tango. The three characteristics of Tango's unique motion tracking, depth perception, and environmental learning, combined with its unique compactness and portability, allow users to Accurately measure all the data related to the feet through 3D modeling of AR. These data are required by third parties.

Yu Xiaodong also told Lei Feng that the Bigfoot app is not just measuring foot length. They also plan to join the foot width, toe height, foot height and arch circumference, and even promote to the height and height. Measurements of other parts of the body, such as head circumference.

We hope to use AR technology to assist the transformation and upgrading of China's manufacturing industry and create human body big data belonging to the Chinese people themselves.

However, at present, Yu Xiaodong thinks that Tango mobile phones or AR-enabled mobile phones have not been widely used, so it is still too early to rush to launch 3D measurement products for ordinary users. Instead, it is a more reasonable development direction for manufacturers to provide them with technical support behind industrial upgrading and transformation.

Yu Xiaodong also mentioned that it is not difficult to develop such a product based on the existing API of Tango.

Tango is a very good tool for the acquisition and modeling of 3D images has been very good support, we basically call the ready API interface in this demo, and then combine some of the subsequent noise reduction and human foot information The specific algorithm will get the result. Of course, we have to optimize in the later mature version.

When asked about the view of AR/VR technology, Yu Xiaodong said: "I'm a technical originator. For those of us who do technology, I think that since the advent of AR/VR technology, it was like development. The people have opened a new door. Many of the things that they had never even wanted to think about before are now achievable. This is a revolutionary event."

Liu Dian thinks: “Now, the entrepreneurship circle has a very bad ethos. Whatever it is to keep it fresh is not willing to do some basic technical accumulation. It wants to follow the latest outlets, but often overlooks it. This 'new' is actually in exchange for years of technological accumulation."

Talking about the feelings of this Tango Development Contest, Yu Xiaodong, now in his forties, demonstrated the unique enthusiasm of young people. He said: “It's just exciting! It feels like you’re bloody. Although only we two Personally, to develop, debug, prepare for PPT and occasionally deal with the company's business, it's just too busy to come, and it's hard to rest these days.But in the face of a new technology, a new door is open to you, you simply I can't help but live with that excitement. It's like saying: "Pain and be happy!"

Finally, the brand manager of Lenovo Accelerator Zhang Yuekai explained to Lei Fengnet why he chose the "Bigfoot" team.

We think that this team has certain technical barriers, and it is also more reliable in software creativity and business planning. What's more important is that we understand that the entire company team behind them is also relatively more complete and mature. Lenovo Accelerator and contest instructors were unanimously endorsed.

In addition, she also revealed that Lenovo will host a similar competition next year. The venues currently under consideration may be at the headquarter of Lenovo Venture Capital Group in Beijing, Phab2 Pro mobile phone research and development site in Shanghai, or Taiwan.

It is worth mentioning that before the finals began, the scene also ushered in a special guest: Premier Li Keqiang. He personally experienced a team's entries and highly appreciated Lenovo Ventures and all participating teams.
