In the field of drones, you must have heard of DJI's AccTIve track intelligent follow-up function, which uses image recognition and machine learning techniques to achieve the purpose of target tracking; however, image discrimination is often done because of The weather, the darkness of the environment, and even the light is too strong. In order to avoid this situation, the University of Taiwan Electrical Engineering team developed the ifollow function, which allows any unmanned vehicle to receive radio waves for tracking purposes. This technology was exhibited at the Consumer Electronics Show in 2018 (CES 2018). Mao Shaogang, professor of electrical engineering and telecom engineering at National Taiwan University, explained that the current mainstream practice of UAV target tracking in the market is to follow the subject matter by means of image recognition, but such methods are often limited by environmental factors. Unable to work. For example, the car accident that occurred in Tesla a few years ago was caused by the strong obstruction of the obstruction in front, which made it impossible for the system to pass, which caused regret. Mao Shaogang takes the Dajiang UAV as an example. If the followers wear green clothes and walk into the turf, or walk behind the shade, the image tracking function of the drone will immediately become invalid. So he began to think about whether electromagnetic waves can be used to solve the pain points of image recognition technology. The ifollow technology demonstrated in CES 2018 is based on receiving radio signals from designated targets. In fact, there have been similar radio wave following techniques in the past, but users have to wear extra radio transmitters (such as belts) on their bodies. The technology exhibited at the National Taiwan University will allow the target to carry unnecessary items. Equipment allows unmanned vehicles to follow their footsteps. Mao Shaogang explained that this technology is not only suitable for the application of unmanned vehicles, but also suitable for import into the store cart; the concept is to install ifollow technology on the smart shopping cart, no additional sensors are needed on the shopping cart, consumers Simply turn on the relevant application on the mobile device to enable the ifollow function to detect and follow the relative position of the device to the user. Consumers do not need to install other hardware accessories on their mobile devices. Ifollow technology can be paired with the mobile network, Wi-Fi and Bluetooth. In addition, RFID can also be installed in the shopping cart to record which items the consumer has selected, calculate the total value, and immediately calculate and present it in the user's mobile device; at the same time, the purchase information will be synchronized. Pushed to the cloud, and then passed to the cashier counter, and finally use the gold stream to connect to the FinTech way of checkout, but also allows the store to calculate the current inventory on the shelf, and replenish the replenishment order.
Flexible LED Mesh Video screens also called Soft Led mesh curtain display screens give you the opportunity to take out your creativity to work. work with this series of products, there's no limit of creative idea and thinking They are hi-definition LED displays with outstanding contrast & brightness levels.
