SI'S 3D ToF series boasts both iToF and dToF technologies, representing a domestically developed 3D vision sensing solution with complete independent intellectual property rights. Utilizing advanced processes such as back-illuminated and 3D stacking, the products achieve a ranging accuracy of up to 1%, exhibiting excellent detection efficiency. They also feature ultra-low power consumption, high frame rate, strong light interference resistance, and suppression of multi-device crosstalk. Compact size and outstanding cost-effectiveness ensure independent control over core technologies and the supply chain. iToF excels in high-precision imaging at short to medium distances, while dToF is suitable for medium to long distance ranging and spatial positioning, comprehensively covering diverse application needs. This series has a wide range of applications. In the consumer market, it can be used for 3D face recognition, AR interaction, portrait photography, AR/VR spatial modeling, and gesture recognition in smartphones. In the industrial and smart hardware fields, it supports SLAM navigation, obstacle avoidance, logistics volume measurement, and industrial visual inspection for service robots. It is also deeply applied in smart cockpits, vehicle sensing, security liveness detection, and smart home interaction, making it a superior alternative for domestically produced 3D vision sensing chips.
