The 2-megapixel wide dynamic dual-camera used in the Hikvision access control all-in-one machine achieves three-dimensional stereoscopic perception through binocular disparity calculation. Its core value is reflected in the following aspects:
Depth Learning Algorithm Support:
Based on the binocular disparity principle (the formula Z=BF/D), depth information is constructed and combined with convolutional neural networks to achieve millisecond-level facial feature comparison. This makes it possible to have an identification speed of 0.2 seconds and a verification accuracy rate of 99%.
**Enhanced Environmental Adaptability**:
The starlight-level sensor (with a minimum illumination of 0.0001Lux) combined with wide dynamic range technology (120dB) effectively deals with complex outdoor scenarios such as backlighting and low light, meeting the IP65 protection requirements.
Anti-Counterfeiting Security Mechanism:
By synchronously capturing live micro-expressions and texture details with dual cameras, it can identify forged attacks such as electronic photos and videos, with a false recognition rate of less than 0.001%.
