¡¤ Ams Osram TMF8801 direct time-of-flight (dToF) sensor can trigger a facial recognition system with accurate distance measurement function;
¡¤ The ToF sensor's excellent anti-sunlight interference capability makes it adaptive to the environment, so that the Kaidis electronic lock can achieve reliable detection in various lighting environments;
¡¤ Through optimized algorithms, ToF sensors can provide intelligent human occupancy monitoring functions and greatly reduce power consumption.
The world's leading optical solutions leader ams Osram (SIX: AMS) and the world's leading supplier of smart locks jointly launched the latest smart electronic lock, using ams Osram's TMF8801 sensor, which can input distance information into the face Department identification system.
With the rapid development of smart locks and the introduction of the market, smart locks have become an indispensable part of the smart home ecosystem. Factors such as high performance, safety, multi-function, and intelligence have now become key attributes of electronic lock products.
Kadish K20 and K20 Max series products use the Ams Osram TMF8801 sensor, which integrates a VCSEL infrared transmitter, multiple SPAD (single photon avalanche photodiodes) light detectors, time-to-digital converters and histograms The processed on-chip microcontroller can provide excellent performance. Compared with the uniform distance measurement method used in the indirect ToF system, the direct ToF time measurement method used in the TMF8801 can provide higher accuracy and more realistic distance measurement results.
Ams Osram's TMF8801 ToF sensor enables a more accurate, more efficient, and more energy-saving solution for occupancy monitoring and facial recognition
TMF8801 has a solar anti-interference filter, so it has excellent anti-interference ability, and can achieve accurate ranging even in sufficient sunlight. At the same time, it also has a high dynamic range, measuring from 20mm to 2500mm. Whether indoors or outdoors, TMF8801 can detect the presence of people under various lighting conditions.
Utilizing the high-precision ranging performance of the TMF8801, Ams Osram and KDS have developed an optimized algorithm to prevent the electronic lock sensor from being triggered by mistake when it detects someone passing by the front door.
Barry Guo, Marketing Manager of Ams Osram, said: ¡°TMF8801 can provide more accurate distance measurement functions to help Kaidiz realize more reliable, more efficient and more energy-saving electronic lock solutions. TMF8801 can be used to realize user occupancy monitoring. Detect the presence or absence of the user, automatically wake up the system when the user is present, and automatically put the system into a low-power sleep mode when the user is absent."
