This article presents a pedestrian tracking methodology using an infrared sensor for surveillance applications. A distinctive feature of this study compared to the existing pedestrian tracking approaches is that the road network information is utilized for performance enhancement. A multiple model particle ...

13.The system of claim 1, further comprising an interaction component for collecting information concerning routes of other people and using the route information to update the direction set in real-time. 14.The system of claim 1, wherein the direction set includes a portion where a user travel...
Embodiments is disclosed to detect a locked heading direction of a pedestrian and to predict a path for the pedestrian using the locked heading direction. According to one embodiment, a system perceives an environment of an autonomous driving vehicle (ADV) using one or more image capturing devices...
In this work, we study the pedestrian position tracking problem using a foot-mounted inertial measurement unit (IMU). The IMU consists of a tri-axis rate-gyro, a tri-axis accelerometer and a tri-axis magnetometer. The magnetometer is used for constructing a global reference frame at the ...
The biggest challenge to adequately estimate stride length using IMU data is the significant bias derived from the use of IMUs, which leads to large drifts after the double-integration process. For that reason, the ZUPT method was used. Zero-velocity detection was done by evaluating a threshold...
These solutions include a dual-foot PNS, dual-IMU PNS on one foot and pedestrian tracking using an IMU array. The principle of the dual-foot PNS or the dual-IMU PNS is based on a physical constraint on the position and the attitude information in the course of a pedestrian movement. For...
In quite the opposite, we take the most advantage of encounters and consider them as an “enhancer” for iIPT instead. Figure 3. Indoor pedestrian encounter model for infrastructure-free indoor pedestrian tracking (iIPT). When the user walks arbitrarily with unstable speed, IMU data becomes ...
Additionally, it features raw GNSS data and IMU measurements for accurate positioning and motion tracking. To effectively interpret the nuanced data collected from this varied sensor array, we have developed three distinct sidewalk and pedestrian route segmentation models for the 4K images, stereo ...
The method involves the use of one IMU at the user’s foot. This enables PDR implementation with Zero-Velocity-Updates. This strategy is recognized for providing higher precision in the calculation of stride size and, therefore, in location tracking compared to others that use the IMU on other...
