Did you scan the exhibits on your smartphone 3D?"Wonder Festival" (One Festival) held at Makuhari Messe on February 6.Exhibitors and operations are raising a sense of crisis in a garage kit festival, which is produced with arms, regardless of professional amateur.
2月6日に幕張メッセで開催された「ワンダーフェスティバル」（画像提供：ワンフェス実行委員会）The starting point was the tweet of one of the exhibitors, 44K."Three men holding a smartphone on a strange screen in one festival (I didn't speak Japanese) came to our booth, but I understand now. It's a depth sensor. It was Lidar ...... "It is said that a characteristic pattern of the scan app was seen on the smartphone screen.
Lidar (LIGHT DETECTION and Ranging) is an sensor that irradiates laser light to the target, and measures the distance from the time to reflect and return to the object.It began to be used around 19 years to improve the autofocus performance of smartphone cameras, for example, the iPhone series is equipped with the iPhone 12 or later released in 20.
In fact, this is not the first time that the act of scanning the exhibits 3D has attracted attention at one festival.Around 2018, it became a hot topic on the Internet as "digital shoplifting" and has been featured in the media.
At that time, however, the commercially available 3D scanner was large, and the battery operating portable machine was low accuracy, so it was stopped in some problems.The One Fes Executive Committee said, "If excessively restricted to visit the visitors, it will be a burden on the exhibitors."
However, the situation is different now that the number of smartphones and 3D scan apps equipped with LIDAR has increased.It is a situation that anyone can perform highly accurate 3D scanning, and it cannot be denied the possibility of being used in pirated printing in combination with 3D printers.
According to the One Fes Executive Committee, "In consideration of the progress of the current equipment, it is necessary to alert the exhibitors. We cannot overlook the fact that dealers are anxious or uncomfortable."There were several similar contacts in addition to the tweets.
On the other hand, he analyzed that "the current scan accuracy can be viewed, but it is not realistic to output with a 3D printer and commercialize it."Even scanning for appreciation requires a scan from all directions, and depending on the coloring situation, light is reflected or absorbed, so it cannot be scanned well.In addition, it is difficult to scan when the back and feet of the figure are made into the mirror, or there is glass or acrylic in front of the work, and these characteristics are said to be a measure against scanning.
The One Festival Executive Committee plans to promote the exhibitors with alerts in the future."If you see scanning shooting, please contact the dealer reception or the secretariat," he said.
The next one festival will be held on July 24 at the international exhibition hall of Makuhari Messe.Participation manual will be released in mid -February.
