Which security industry technology trends did you miss during the Spring Festival? 【full text】

The time of science and technology dynamics it is always silent, inadvertently quietly slipped away. In the shortest of February of the year, it was on the warmth of the spring and it was switched to March. Goodbye in February, Hello in March! The security industry is an industry that is constantly evolving and changing. So, in the past few months, what new technology trends in the industry? What new products are worth our attention?

Scientists invent crawl robots for search and rescue or medical use

According to the British "Daily Mail" on February 23, in the latest batch of robotic development projects, Harvard researchers used artificial scales to invent a robot that could crawl like a snake. This robot can be used for medical aid and search and rescue missions.

According to a new study published in the "Science" magazine's robotics magazine, scientists at Harvard University have realized the use of artificial scales to create a robotic robot that can crawl like a snake. It can slide in water and open doors. Lift objects more than 1,000 times their own weight. The researchers designed this software robot using a paper-cut art called "kirigami". Kirigami is a variation of the origami art that relies on cutting rather than folding.

Harvard University's research team believes that this robot can be used for medical assistance. Researcher Katia Bertoldi said, “The kirigami sensing structure we used in this robot opens the way for the design of new software robots.” He also emphasized that “one day, these soft robots that can adapt to any terrain can cross difficult environments. , conduct exploration, inspection, monitoring and search and rescue missions, or perform complex laparoscopic medical procedures."

Japan develops LED display with attached body

According to reports in the Japanese media, the research team of professor Yokoguchi Takashi (Electronic Engineering) of the University of Tokyo has successfully developed a thin LED display that can be flexibly attached to the human body and is trying to apply it to fashion and medical related fields.

The team also tried to make a film that fits with sensors that also attach to the human body to show the ECG curve. Sugoku said: "It can also be used to replace smartphones and tablets to display information."

The display is 1 mm thick. Because of the retractility, the length of the video that can be displayed is 3.8 to 6.4 centimeters, and the width is 5.8 to 9.6 centimeters, which corresponds to the size of the business card. The rubber film stretched to a very thin level is equipped with 384 small red LEDs. Because after wrinkling processing, after 10,000 telescopic experiments, the LED is not damaged, and the video can be displayed normally.

Israel develops anti-facial recognition technology

According to the report of Japan's livedoor news network, although facial recognition technology has provided us with convenience, many people also feel fear. To counteract this concern, the “D-ID” company, headquartered in Tel Aviv, Israel’s second largest city, has developed a new technology that can protect image data and prevent it from being recognized by facial recognition technology without permission.

D-ID wants to overcome facial recognition security by creating a facial data that is exactly the same as a particular person. However, breaking through security in this way is quite troublesome. Because faces and passwords are not the same, they cannot be easily changed. This technology of D-ID Company can finely rewrite the face photo data, and the human eye can't see the difference, but the processed photo cannot be detected by the facial recognition algorithm.

CRA develops multi-sensor "flybar" intelligent road system

The International Design and Innovation Agency (CRA) recently cooperated with the Italian highway operator ANAS to develop an intelligent road system with a multi-sensor "flying bar". Sensors installed on the two poles of the system will detect environmental variables in the road coverage area, including air pollution, wind speed, and humidity. The manager uses the data collected by the sensors to notify the driver of the real-time traffic conditions in front of the driver's mobile phone or on-board display so that the driver can plan the route in advance.

SICK Launches New TIC502 Lidar Sensor System

SICK, a German sensor technology developer, has recently launched the TIC502 Lidar sensor system, which can be installed in a highway control room to achieve all-weather traffic control in any climate zone. The system detects vehicle speeds up to 100 times per second, generates 3D contours for each vehicle and integrates them into the display, and automatically derives traffic flow information by moving vehicle data. In addition, the TIC 502 can also be used as a trigger for DSRC and ANPR cameras to enable integration with different traffic management systems.

Cloud from the technology first 3D structured light face recognition technology

Cloud Technology officially announced the launch of "3D structured light face recognition technology" on February 7, 2018. It has achieved a significant improvement in security, recognition accuracy, and recognition speed. Its accuracy rate is one in 10 million. With 99% or more released, the speed is reduced from 1-2 seconds to milliseconds. In addition, it is better protected against frauds such as masks and videos.

It is reported that the new 3D structured light face recognition system of Yunzi Technology is based on "Dragon II" deep learning structured light algorithm and 3D structured light depth camera. The structured light camera includes an infrared transmitter, an infrared camera, a visible light camera, an internal point cloud reconstruction unit, and an image processing unit. The infrared emitter emits an infrared light source such as a bitmap (speckle)/stripes, etc. to acquire single-frame/multi-frame images with speckles/stripes; the infrared camera receives infrared IR image information on the surface of the object for reconstruction of the 3D point cloud; The point cloud rotates through the space coordinates to obtain 3D face point clouds in various angles. These 3D face point clouds can be complemented with RGB color face images to get a more accurate 3D face model.
