Massachusetts-based Analog Devices has introduced an algorithm for people detection and counting in indoor spaces such as meeting rooms or office cubicles.

The EagleEye ADSW4000 PeopleCount is the first in a series of application-level software algorithms forming part of the company’s EagleEye platform that includes a hardware subsystem based on its Blackfin embedded digital signal processor (DSP) and a set of application-level software building blocks helping users quickly develop their own people counting system.

The algorithm provides system edge node analytics that unlock insights to improve space use, people safety through distance monitoring, and energy efficiency of spaces within intelligent buildings.

The people counting algorithm for indoor areas, such as meeting rooms or office cubicles, can provide occupancy state and location of a person using x and y coordinates.

Zoned performance allows it to check multiple areas for larger coverage. Edge processing allows metadata output over uart. No captured images are transmitted.

The coverage area for an optimal accuracy of 90 per cent is a three-metre radius. Maximum coverage area for an accuracy of 80 per cent is a five-metre radius.

The EagleEye platform enables a complete, end-to-end hardware and software installation to help solve occupancy problems. Combining the proprietary ADSW4000 algorithm and Blackfin DSP enables efficiency of indoor space while maintaining security and privacy as images are processed but not transmitted from the edge node.

From meeting rooms to cafeterias, and lobbies to open desk people counting, it can solve workspace problems and increase worker wellbeing and productivity.

Analog Devices has a suite of analogue and mixed signal, power management, radio frequency (RF), and digital and sensor technologies. It serves 125,000 customers worldwide with more than 75,000 products in the industrial, communications, automotive and consumer markets. Its headquarters are in Wilmington, Massachusetts.
