The naked eye 3D

holographic projection makes the internal structure of the protein clear, the sign language recognition system will realize the communication between the deaf and the sound, and the intelligent escort robot can monitor the change of the infant's emotion in real time, and the intelligent street lamp control system will save 25.9% of the energy consumption. A few days ago, the tenth session of Beijing University of Posts and Telecommunications's innovation and entrepreneurship achievements exhibition and innovation and Entrepreneurship Forum opened.
The exhibition and Innovation Forum has received more than 190 exhibition works, involving intelligent life, digital entertainment, media design, intelligent equipment, public service, medical health, robot, education culture and many other fields. The project covers VR, AR technology, holographic projection, deep learning and so on. Hot technology.
As a member of the "naked eye 3D holographic projection assistant teaching tool", Dong Yu Shun, 2015 of the North Post Communications Engineering major, said, "when explaining protein in a biological course, the previous projector can only show a flat picture. We present it by building a three-dimensional model of protein. The 3D structure can be rotated and zoomed by sliding screen control model to help students understand their internal characteristics.
The technology of computer recognition for speech is already mature, and the project developed by 5 undergraduate students at the 2015 level of North mail enables the computer to read "sign language", which brings new possibilities for the exploration of sign language translation and sign language teaching. Only when the team members made a hand stretching gesture in front of the camera, a stop word appeared immediately on the screen. At present, the sign language recognition system has been able to accurately identify 50-60 specific gestures, and facilitate the life and communication of hearing impaired people.
"We use the convolution neural network for facial expression recognition, we can analyze the emotional changes of infants and children, so that parents can understand the situation of children through mobile phones anytime and anywhere, and reduce the burden of the baby." Mao Kaining, a 2015 class student of Electronic Science and technology in North mail, developed a "intelligent escort robot based on Emotional Analysis" with 3 other team members, which can judge seven common emotions, such as joy, sadness and anger. It can also help the parents to respond to the parents' immediate feedback. .
