Method and system for tracking people in indoor environments using a visible light camera and a low-frame-rate infrared sensor

摘要

A method and system tracks objects in an environment by acquiring a first sequence of images of the environment with a visible-light camera having a first frame rate and a second sequence of images with a thermal infrared sensor having a second frame rate. The second frame rate is substantially lower than the first frame rate. The objects are tracked in the first sequence of images to obtain tracks. Warm regions in the second sequence of images are detected to obtain detections. The tracks and the detections are aligned spatially and temporally, and verified to determine whether the tracks and detections coincide after the aligning.

1. A method for tracking objects in an environment, comprising:
acquiring a first sequence of images of the environment with a camera having a first frame rate, wherein the camera is a visible light camera; acquiring a second sequence of images of the environment with a sensor having a second frame rate, wherein the sensor is a thermal infrared (IR) sensor, and wherein the second frame rate is substantially lower than the first frame rate; tracking objects in the first sequence of images to obtain tracks; detecting warm regions in the second sequence of images to obtain detections; aligning spatially and temporally the tracks and the detections; and verifying whether the tracks and detections coincide after the aligning.
