Baby Footprint Scanner Product specification manual

Describe：

Product Introduction

Product Features

Ultra-high image quality: Optical distortion-free imaging system that captures images with high fidelity for easy extraction

Capture function is powerful: capture window size is large, support the capture of foot print, single finger, multi-finger image

fast acquisition speed: acquisition speed of at least 7 frames per second, support real-time pattern detection

Footprint and fingerprint processing algorithms: support for generating and comparing footprint and fingerprint features.

Adaptable: Applicable to various types of grain, automatically removes residual grain marks and halo effects, higher imaging quality

Durable and shock-resistant: sturdy shape, wear-resistant, shock-resistant and anti-vandalism, anti-static interference, long service life

secondary development is simple: provide Windows and Android platform SDK development kit
