Binocular 3D regional passenger flow heat map product specification -万服科技

Chapter One Product introduction

1.1 Product Overview

The product of passenger flow and heat area in binocular 3D area obtains 3D depth information in real time through binocular AI sensor, identifies the head and shoulder features in complex scenes based on the head and shoulder feature algorithm, and realizes accurate 3D human tracking through the human body tracking algorithm. Based on this technology, the information of passenger flow, stop and heat in the set area is statistically analyzed. So as to realize the passenger flow statistics and thermal analysis function of the region.

1.2 Product Features

(1) High statistical accuracy

Based on the leading binocular stereo vision technology, it gets rid of the limitations of traditional 2D products which are easily affected by light and scene.
Based on the leading fisheye binocular imaging technology, the available field of view Angle is increased to 140x120 degrees, and the coverage range of 9mx6m can be realized at 3.5m.

(2) The reference frame of the visual view is clear

Thanks to the 3D human body detection and tracking technology, the thermal map reference system refers to the ground instead of based on the human head, so it is easier to use in the secondary development of the data. At the same time, the data is accurate and not affected by different heights of people

(3) Provide both thermal map and thermal data;

It not only provides the thermal data after rendering, but also provides the accurate data behind the thermal map. Customers can do qualitative research or quantitative analysis;
It provides multi-dimensional data such as duration, number of people and number of people who stop, with richer data.

(4) Edge computing, simple deployment

Benefiting from leading 3D tracking technology, no more scene optimization is required after product deployment
Adopting the all-in-one mode, there is no need to add edge computing boxes and other devices

1.3 Function Description

This product contains four sub-functions, as shown below:

1.3.1 Definition of regional passenger flow

Regional passenger flow is divided into two data dimensions: total regional passenger flow and regional stopping passenger flow.

(1) Total regional passenger flow

For each customer, from entering the observation area to leaving the observation area, the total number of passenger flows will be +1.

(2) Passenger flow in the area

If a customer entering the observation area stops at a point in the area for more than the set time (currently 3S), the number of passengers stopping in the area will be +1.

1.3.2 Duration Heat map

The floor is divided into grids. Each grid, as a unit, accumulates the total time spent in the grid by all customers. This data dimension reflects the heat passed through each small area on the floor.

1.3.3 Heatmap of head count

Each grid on the ground, as a unit, accumulates the total number of customers that have appeared in this grid, which reflects the specific distribution of the number of people data.

1.3.4 Stop heat map

Each grid on the ground is used as a unit to accumulate the total number of customers who have stopped in this grid, so as to analyze the degree of interest of customers in different locations.
