Page 15: Facial Registration Image Quality Requirements
• The whole face should be in the camera frame and the aspect ratio of the face must not be distorted. • Face contours should be clear and the light must be even. • The facial expression should be natural without obvious exaggeration. P a g e | 15 Copyright© 2022 ARMATURA LLC. All rights reserved.
Page 16: Palm Recognition Algorithm
In this appoach, the robustness and pass rate are considerably improved. The algorithm applies to various palm postures as shown in Figure 3.3: Figure 3.3 Definitions of palm postures P a g e | 16 Copyright© 2022 ARMATURA LLC. All rights reserved.
Page 17: Palm Recognition Specifications
• The whole palm (including the wrist) should be in the camera frame and the aspect ratio of the palm must not be distorted. • The palm angle tolerance for pitch, roll, yaw, and bend should be ±5 degrees. P a g e | 17 Copyright© 2022 ARMATURA LLC. All rights reserved.
Page 18: Application Scenarios
Figure 3.4 Example of a palm registration image Application Scenarios The AMT-FAPVS-21 dual-camera modules are optimized in structure based on the design and usage of built-in modules, facilitating quick integration into the host device. Due to the profoundly integrated design, the dual-camera module can be connected to a platform device using a single USB cable.

Page 23: Cable Requirements
Figure 7.1 Specifications of a double-plug cable (Unit: mm) Hardware Design and Integration Guide Optical Design AMT-FAPVS-21 are built-in dual-camera modules. The optical design is included when the modules are integrated into devices. To avoid mistakes in optical design and improve development efficiency, use the following specifications: For the transparent material used in front of a module, such as glass and acrylic, the transmittance should be greater than 85% with a wavelength coverage of 400 nm to 900 nm.
Page 24: Heat Dissipation Design
When a module is integrated into a device, the heat dissipation performance is improved by using a thermal conduction design. Similarly, the AMT-FAPVS-21 dual-camera modules are equipped with structural metal components capable of heat dissipation. A thermally conductive silicone pad is added to the back of the structural component.
Page 25: Installation Guide
Figure 8.4 Thermal conduction design Installation Guide Installation Modes Considering the built-in design of the AMT-FAPVS-21 dual-camera modules, it is recommended to use either rear-locking or front-locking mode to install and mount a module. Figure 9.1 shows a rear- locking mode.
Page 26: Installation Height And Angle
User Manual Installation Height and Angle When you install an AMT-FAPVS-21 dual-camera module, you need to consider the influence of the installation angle and height on the field of view for image collection. If the mixed face/palm recognition algorithm is used, you need to consider the field of view that faces can adapt to, the range requirements of palm recognition, and the convenience and speed of man-machine interaction.
Page 27: Horizontal Installation Mode
1.45 m. If a person can be recognized at a distance of 0.5 m to 0.8 m, the module can adapt to individuals with height is between 1.45 m and 2.18 m, as shown in Figure 9.4. Figure 9.4 Slant installation P a g e | 27 Copyright© 2022 ARMATURA LLC. All rights reserved.
