Role of ToF Sensor Modules in People Counting

Time-of-flight (ToF) sensor modules have proven a revolutionary concept in people counting applications worldwide. With the utmost precision guaranteed and unique considerations in place regarding personal privacy and data protection, ToF sensors can enable people counting solutions which offer superb insights into a variety of key business metrics, from periodic footfall to space optimization.

A Brief Introduction to People Counting

The inherent value of people counting is often overlooked. Research has shown that global businesses are collectively wasting up to $1.5 trillion USD through inefficient use of space. Another study suggested that many businesses could effectively reduce their workspace by up to 30% through smarter utilization of the space available. However, achieving these savings requires a thorough understanding of how space is occupied and used in regular conditions. Counting systems based on ToF sensor modules excel in this area, but they are still relatively unknown to facility managers.

Some retailers still make use of clickers today; manually tracking footfall to gather data for statistical analysis. Yet this rudimentary technique is limited in both scope and reliability, running the risk of inaccuracies due to human error. As businesses have come to understand the value inherent in the relevant metrics, more sophisticated methods have arisen to assist with people counting in various sectors, including video CCTV with software integration and advanced WIFI capabilities.

In a previous blog post, we explored the potential cost savings – and some of the key technologies, such as thermal cameras, CCTV, stereo cameras and ToF sensors, of modern people counting applications:

What Part Do ToF Sensors Play in People Counting?

Although highly sophisticated, both modern CCTV and WIFI counting systems have problems that are difficult to overcome. The first of these is the issue of privacy. Counting algorithms, such as multi-layer background subtraction, conduct counts based on the color and texture of video feeds. CCTV is common in many commercial and retail installations, but its use is contentious where issues of personal privacy come into play. The second issue concerns the uncertain statistical significance of counts using WIFI management frames.

Consequently, the use of ToF sensor modules is nothing short of groundbreaking. They are class-leading technology in people counting solutions, providing simple 3D information with complete protection of personal privacy. Fully-compatible with a range of doorway dimensions, ToF sensor modules offer the most accurate insights into numerous business metrics. In commercial applications, they can assist in a range of analytical observations including conversion rates, customer visit durations, and footfall trends.

The same metrics can be applied to space optimization applications in busy workspaces and high traffic areas. Recently, we demonstrated the use of ToF sensor modules for people counting in our own offices with outstanding results. They provide actionable data to inform decisions about space utilization, optimization, and future real-estate decisions.
