1. A system for unmanned aerial vehicle (UAV) parachute landing, the system comprising:
a memory storing instructions;
a processor configured to execute the instructions to cause the system to:
determine whether to open a parachute of the UAV in accordance with a criterion; and
responsive to a determination to open the parachute of the UAV:
stop a motor of the UAV that spins a propeller of the UAV,
wait for a specific period after stopping the motor, and
open the parachute of the UAV; and
a detector configured to detect wind direction;
wherein the processor is configured to execute the instructions to cause the system to stop the motor of the UAV when the UAV flies against wind.
