Additionally, ensure that targets
appear in the middle of the video image and the image covers the
entire detection area.
合适的摄像机高度和光照强度能保证图像质量；同时避免目标重叠遮挡，保证不同高矮人员经过时能正常抓拍。确保
目标出现在摄像机画面中央位置，检测画面能完整覆盖到抓拍通道。

Illumination
intensity
光照强度
• The recommended illumination ranges from 200 lux to 900 lux.
•
建议
200lux~900lux
。
• The outdoor direct sunlight intensity may exceed 900 lux. If the capture effect is
unsatisfactory, add a sunshield for the camera.
•
室外太阳直射光照强度可能超过
900lu
x，若抓拍效果不理想，需增加遮阳设备。
• To capture images at night, install an illuminator for the camera or select a bullet camera
with a built-in illuminator.
•
若需夜间抓拍，要安装补光灯或者选用自带补光灯的筒机。

Pedestrian requirements
行人要求
Moving speed
行进速度
• Normal walking speed, neither cycling nor vehicle driving
•
正常步行速度，无骑行，无人车混杂。
Moving
direction
行走方向
• Pedestrians travel direction. For instance, at the turnstile or campus entrance and exit,
pedestrians walk through a designated path to facilitate image capture.
•
行人的行走规律，比如闸机、园区出入口，行人按照约束的通道行走，以便于抓拍。
Camera installation requirements
摄像机安装整体要求
Camera
installation
location
摄像机安装位置
• The recommended camera installation height ranges from 2.5 m to 3.5 m.
•
摄像机安装高度一般为
2.5
米
~3.5
米；
• The width of the optimal capture area is generally less than or equal to 3 m.
•
最佳抓拍位置覆盖宽度一般不超过
3
米；
• The camera should directly face pedestrians to ensure a better capture effect. Therefore,
it is essential to consider the installation position and image coverage width during scene
selection.
•
摄像机需正对行人，角度越正抓拍效果越好。建议在场景选择时，考虑架设位置和画面覆盖宽度。
