Beschreibung
Zusammenfassung:	The invention provides an airflow field measuring device, an airflow field measuring method and a plant protection spraying operation machine, the device comprises an air supply device, a particle emitter, a laser radar detector and a processor, the air supply device is used for supplying air to generate a target airflow field; the particle emitter is used for emitting particles to the target airflow field under the air supply action of the air supply device; and the processor is used for determining the wind speed of the target airflow field based on the point cloud data of all the target particles in the target time period. According to the airflow field measuring device provided by the invention, the particle emitter is controlled to emit particles under the action of the air supply device, so that the movement and distribution conditions of air-blown spray particles in the airflow field can be simulated, and then the air speed of the target airflow field is determined according to the point cloud data of
