    摘要: A method and device for planning spraying operations, a control terminal and storage medium are provided. The method includes: obtaining and displaying a flight route of a UAV, and controlling the UAV to execute a spraying operation along the flight route, where the flight route includes a plurality of segments including spraying segments and non-spraying segments; obtaining an interruption position of an interruption segment; based on a position of the UAV, determining whether there exists a projection position within the first preset number of spraying segments that have not been executed after the interruption segment without determining whether there exists a projection position of the UAV within the non-spraying segments; and displaying indicator(s) to indicate the position of the return position(s) on the flight route. The present disclosure can meet the user's expectations and conserves electrical energy consumption, thereby improving the efficiency of executing spraying operations.

    摘要: A seismic weight dropper arrangement for a drone. The arrangement comprises a winch assembly attachable to a drone and comprising an actuator and spool with a cable windable thereon. Arrangement also includes a seismic source assembly comprising a housing and a mass suspended within the housing via at least one resiliently elastic biasing element, such as a coil spring. The seismic source assembly is fast with the cable and the actuator configured selectively to eject the seismic source assembly from the drone under the influence of gravity. The resiliently elastic biasing element has a predetermined modulus of elasticity to facilitate the mass impacting the housing when the housing impacts a surface after such ejection from a predetermined height above the surface.
