According to official data, Huawei's R&D expenditure in 2021 was RMB142.7 billion, accounting for about 22.4% of its annual revenue, far exceeding that of other technology companies. According to the "2021 Patent Index" report released by the European Patent Office, Huawei applied for 3544 patents in Europe in 2021, surpassing Samsung to rank first. Recently, a number of Huawei patents have also been exposed, covering a wide range of fields, such as face images, unmanned driving and chips that everyone pays more attention to, so what are the specific achievements? Let's take a look!
Chip stacking packaging and terminal equipment patent
In the face of the restrictions of consumer business, Huawei has also increased its research and development efforts in the chip field. Recently, it was learned from the official website of the State Intellectual Property Office that Huawei has published a patent for chip stacking packaging and terminal equipment, and the application number is CN114287057A, which can ensure the power supply demand while solving the problem of high cost caused by the use of silicon through-hole technology.
This patent may be related to the chip design scheme of the multi-core structure previously revealed by Guo Ping, Huawei's rotating chairman. In simple terms, it is possible to use a less advanced process to enhance the competitiveness of Huawei products, at that time, someone revealed that the way Huawei uses is to increase the area, use the stacking method to improve performance, and its CPU package stacking technology can use 14nm packaging technology to stack the performance effect of the 7nm process.
Although chip stacking is not a new technology, since Huawei has published relevant patents, we have reason to believe that it has completed basic tests and experimental tests. According to the director of the factory is Guan Student blogger revealed that the stacked chip will meet with us in 18 months, Huawei's use of its own architecture of the stacked chip is really not far away.
Patents related to autonomous driving
According to the patent of the State Intellectual Property Office, Huawei recently published a patent related to autonomous driving, which is "the detection method and system of the vehicle driving area and the autonomous vehicle using the system", which includes the use of a neural network to distribute the first probability of the obstacle to the envisaged device, and then obtain the second probability obstacle distribution according to the radar echo signal.
This patent is actually a vehicle driving process obstacle detection method, with the camera and radar two sensors on the obstacle information fusion, to see if the vehicle can pass, the previous data show that Huawei has announced 54 automatic driving related patents, which also proves that Huawei will be on automatic driving in the future.
Method and device for removing glasses in face image
Huawei also recently announced a patent related to face image recognition technology, which is "a method and device for removing glasses from face images." The technique first extracts facial features from the human face, then determines the features of the human eye area, filters the parts with glasses, and obtains an image without glasses. Simple understanding, that is, to be able to supplement the pixels where the glasses are located, to avoid the loss of face information.
This patent will most likely be used in face recognition, improving the accuracy and safety of the use of facial recognition by people wearing glasses, regardless of whether glasses are worn or not, the device can carry out more accurate recognition. There is also speculation that the patent will be used in mobile phone image editing, somewhat similar to the one-click removal of glasses function.
