"The "Hybrid Vision" technology of RISZ is independently developed by our team. This technology integrates the team's understanding and accumulation of various advanced visual sensing technologies and event camera technologies in the past 15 years, and is formed by fusing some advanced visual sensing technologies with bionic event camera technologies at the sensor pixel level. At present, our first chip ALPIX-Pilatus based on "Hybrid Vision" technology has been successfully taped out, which also verifies the feasibility of our technology. Our success at the first tapeout is also due to the team’s past experience in the field of chip design.
We currently have applied for more than 30 domestic, PCT and other countries or regions patents around the "Hybrid Vision" technology, and are still applying for it.
Our chip has three main advantages:
(1) Compared with the existing bionic event camera chip that requires a dual-camera solution with a traditional image sensor in most scenarios, one chip of the ALPIX series can replace two chip functions, which not only has a system cost advantage, but also has more data. Rich.
(2) Solve the problem of dual-camera heterogeneous registration. In the dual-camera system of event camera chip + traditional image sensor, due to the difference in viewing angles of the two cameras, real-time registration of event camera data and image data is required. Event data and image data are two completely different types of data, and spatial registration is difficult, which brings great difficulties to the realization of the underlying fusion algorithm. The ALPIX series chips naturally solve the problem of difficult spatial registration because the two types of fusion signals are generated by the same pixel.
(3) ALPIX can output image signals and is compatible with existing image processing algorithms and architectures.
Most of the current event camera field is based on the core architecture design of Professor Tobi Delbruck of ETH. It has the advantage of ultra-low latency. The chip can reach an equivalent frame rate of 100,000 frames per second. Therefore, It has advantages in some high-end special scenes such as industry. However, it is also difficult to output high-quality traditional image signals.
We mainly follow the technical route of integration. The goal is that the chip can output two channels of event stream signals and high-quality traditional image signals to meet application scenarios that require two types of signals, mostly consumer electronics. Therefore, our application goals and technical logic are quite different."
