What you can do with 人数计数器

Everything this tool helps you accomplish — no learning curve, no setup.

  • Count people in a photo or crowd automatically
  • Estimate event attendance from a single image
  • Tally heads in classrooms and gatherings
  • See each counted person marked on the image
  • Include people facing away from the camera
  • Turn on max accuracy for dense crowds
  • Fine-tune detection for small or distant faces

Settings information

Every control in 人数计数器, explained — what it does and when to use it.

数量

ConfidenceSliderRange: 0–1 · 默认: 0.05
计数完成后重新筛选已标记的人物——滑向「仅高置信度」可剔除存疑的标记,滑向「显示更多」则纳入不明显的人;人数即时更新。
Overlay style预设
设置已计数人物在预览中的呈现方式——打点、密度热力图、两者兼有,或不加标记的干净图片——方便你直观核对人数。选项: 两者DotsHeat
Include people facing awayOn / Off
Counts people turned away, in profile, or whose face is hidden — not just visible faces — while never counting one person twice and never counting legs alone as a person. For genuinely dense crowds it escalates to a density estimate.
最高精度(速度较慢)On / Off
在照片上运行全部计数引擎并交叉核对结果,得出最可靠的人数,处理时间会稍长一些。
识别灵敏度SliderRange: 0–1 · 默认: 0.5
控制标记人物的积极程度,从“严格”到“宽松”——若小群体中的人被漏掉请调高,若非人物体也被计入请调低。

常见问题

It picks the right engine for your photo. In small groups every visible face counts as exactly one person — someone sitting, crouching or partly hidden is never counted twice — and people facing away from the camera are added from a full-body check, each with a numbered box you can verify. Dense gatherings switch automatically to an AI crowd-density engine, trained on crowd datasets, that keeps counting where bodies overlap and detectors lose track.

usage

可以——密集人群由专为此类场景打造的人群密度引擎处理,配有热力图和点位显示计数的来源。为获得最佳效果,请使用更高视角、更宽的拍摄画面,让人群完整入镜。

quality

可以——使用物体计数器即可统计硬币、药片、零件、商品等物品。

features

Yes, free with no signup. Free downloads of the marked-up image carry a small “Counted with Pixoate” badge; with Premium that same download is watermark-free. Photos are uploaded only to process and deleted automatically afterwards — we never keep or share them.

privacy

是的 — 它可作为单张图片的人群计数器使用。上传一张从高处拍摄的宽幅人群照片,它会把检测到的每个人框出来并报告人数,让你无需手动数人就能估算活动、演唱会、教室或集会的到场人数。为获得最佳估算,请从高处拍摄,以减少人与人之间的重叠。

usage

将其保持为“自动”,它会逐人检测小群体,并在拥挤场景下切换到人群密度引擎。如果密集人群被数少了,就调高灵敏度滑块,让相互重叠的头部仍被数到;如果稀疏场景被数多了,就调低它。把结果叠加切换为热力图可查看密度集中在何处,或切换为打点以逐一核对检测结果与总数。

人数计数器 如何助您完成任务

它每天都在解决真实的问题——服务企业、创作者和日常任务。找到适合您的用例,几秒即可开始。

活动

活动与会议出席对账

拍下房间或场地,即时获得人数统计以核对票务销售或出席回复名单,无需门口计数器或手工计数。

出版

集会与抗议活动的人群规模估算

使用 AI 人群密度引擎,从一张俯拍或广角照片中获得客观的人群估算——它正是为手动计数失效的密集、人体重叠场景而打造的。

面向企业

零售客流和排队快照

通过一张照片清点排队或店面前的顾客,以抽查特定时刻的客流量或排队长度,无需摄像头系统。

教育经历

教室与会议考勤登记表

拍一张房间的照片,即可立即得到人数用于考勤登记,而不必人工点名。

法律

场地容量与消防安全抽查

从一张照片核对房间或场馆是否符合其额定容纳人数上限——在向公众开门前做一次快速的合规抽查。

旅行

交通站台与候车区人流检查

拍下火车站台、公交站或候车区,即时获得人数统计或密度估算,用于运力和拥挤程度的决策,无需安装专门的人流计数摄像头系统。
