Abstract: A method and a biomechanical parameter determination system (BPDS) for determining biomechanical parameters of one or more target objects in a region are provided. The BPDS dynamically receives first data including temperature data and/or motion data of target objects in the region from first sensors and dynamically receives second data including optical images, sound data, amplitude, and/or distance of the target objects in the region from second sensors, over a network. The BPDS filters the dynamically received first data and second data of the target objects and identifies one or more target objects using the temperature data and/or motion data of the target objects. The BPDS determines one or more biomechanical parameters including, for example, positions, acceleration, walking speed, fall, posture, etc., associated with each of the identified target objects in the region using the filtered first data and/or the filtered second data for emergency alerting and/or health assessment.
