On December 19th, Jingdong’s “Tianji Project 2.0 Annual Ceremonyâ€, uSens, a human-computer interaction technology solution provider, exhibited its independently developed mobile phone AR solution based on a monocular RGB camera for the first time. Unlike ARKit and ARCore, the uSens mobile AR solution not only runs smoothly on high-end mobile phones, but also adapts to low-end mobile phones and performs well.
At the event, uSens technicians demonstrated the same AR's effect on the Samsung S8 high-end machine and a low-end machine that sells for less than 1,000 yuan. Ma Shengyu, vice president of uSens technology, explained that ARKit and ARCore have very high requirements for mobile phones, and they basically match the top models. For low-end and middle-end mobile phones, on the one hand, the chip's computing power is limited. On the one hand, the built-in IMU has poor performance and has many limitations. In order to run SLAM smoothly, the algorithm requires a relatively high algorithm. uSens' mobile phone AR adopts self-developed SLAM algorithm combined with IMU and computer vision, and is optimized for low-end and mid-range mobile phones. It can now achieve precise and stable results.
Open the AR app developed by uSens and Spreadtrum, and quickly construct the plane by moving left and right, and then click the left button, such as the Little Yellow 3D model, to place the virtual object on the real plane. The experience is tested on the low-end mobile phone. Through fast frequency jittering and displacement, blocking the camera, and testing around the rotation, the virtual objects can all remain in place. The position accuracy is in the millimeter range, and the position tracking effect is stable. Similar to the ARCore effect. The CPU usage is even better, compared with 12% for the ARcore CPU on the S8 and only 3% for the uSens. The experiencer can also move, zoom in, zoom out the 3D model, view details, and shoot and share.
uSens said that in 2018, it plans to combine with AR e-commerce, AR photography, and AR live broadcast scenarios to apply uSens' mobile phone AR in different vertical areas to adapt to a wider range of mobile phone models and to allow uSens' mobile AR technology to further land. Change, scene, and commercialization. According to reports, currently uSens' mobile AR solution has established cooperation with Spreadtrum's upstream SOC vendors, and the number of pre-installed devices in 2018 will reach several hundred million units.
