Abstract：At present， underground regional personel restriction algorithms based on video monitoring mainlyrelyon multi-object tracking，which has problemssuch ascomplexcomputation that makes low-power embedded deployment dificult and susceptibilityto environmental light interference.To addresstheabove issues， alightweight algorithm for coal mine regional personnel restriction basedon object detectionand tracking was proposed.Multiple binocular structured-light cameras wereused to colect color and depth images at key entrancesand exits.Based on the improved lightweight object detection model GF-YOLOv8，worker image localization wasachieved.An Intersection-Over-Union priority strategy wasadopted to match objectsand trajectories，which reduced the number of matches compared with traditional tracking algorithms and improved thecomputational speedof tracking.Basedontracking trajectories，the total number of people inkey areas was counted through the cros-line counting method with multiple cameras.When the number of people in the area reached thepersonnel limit，alarm information was generated.The experimental resultsshowed that binocular structured-light cameras effectively overcame the influence of illumination. The AP@0.5 and AP@0.5：0.95 of the improved detection model GF-YOLOv8 increased by 0.24% and 3.42% respectively compared with YOLOv8， while the number of parameters and floating point operations per second decreased by 17.29% and 2.58% respectively.The Intersection-Over-Union priority strategy achieved accuracy close to the DeepSort algorithm but with lower matching complexity. Regarding the count of personnel restriction alarms， there were 17 true alarms; the Intersection-Over-Union priority strategy correctly reported 16 and missed 1 alarm.
