摘 要：Bird flocking is a paradigmatic case of self‐organised collective behaviours in *** camera systems are employed to observe flocks of starlings,jackdaws,and chimney swifts,mainly on a spot‐fixed basis.A portable non‐fixed stereo vision‐based flocking observation system,namely FlockSeer,is developed by the authors for observing more species of bird flocks within field *** portable flocking observer,FlockSeer,responds to the challenges in extrinsic calibration,camera synchronisation and field movability compared to existing spot‐fixed observing systems.A measurement and sensor fusion approach is utilised for rapid calibration,and a light‐based synchronisation approach is used to simplify hardware *** has been implemented and tested across six cities in three provinces and has accomplished diverse flock‐tracking tasks,accumulating behavioural data of four species,including egrets,with up to 300 resolvable *** authors reconstructed the trajectories of a flock of egrets under disturbed conditions to verify the practicality and *** addition,we analysed the accuracy of identifying nearest neighbours,and then examined the similarity between the trajectories and the Couzin *** results demonstrate that the developed flocking observing system is highly portable,more convenient and swift to deploy in wetland‐like or coast‐like *** observation process is reliable and practical and can effectively support the study of understanding and modelling of bird flocking behaviours.
