Abstract

The present invention relates to the technical field of aircraft, and in particular, the present invention relates to a method and device, a terminal and a mobile device for constructing a density distribution map of a target object. The method for determining a density distribution map of a target object includes: acquiring an image collected by a collection device in a target area; determining the density distribution information of the target object in the image to obtain a density distribution map of the target object; the spatial position information and attitude information of the image, and based on the spatial position information and attitude information, determine the projection relationship between the image and the plane coordinate system where the target area is located; The density distribution map is projected onto the plane coordinate system where the target area is located. Through the solution provided by the present invention, the position of the density distribution map of the target object corresponding to the image can be determined, which is beneficial to establishing the density distribution map of the target area.

Description

technical field

[0001] The present invention relates to the field of aircraft technology, in particular, the present invention relates to a method and device, a terminal, and a mobile device for constructing a density distribution map of objects. Background technique

[0002] With the development of science and technology, aircrafts, such as drones, are widely used in aerial photography, agriculture, plant protection, micro selfies, express transportation, disaster relief, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspections, disaster relief, film and television It is widely used in shooting and other fields. When the aircraft performs plant protection operations, mastering the distribution density of the target objects in the area to be operated, such as crops or pests, can pre-control the amount of liquid sprayed and the concentration of the liquid to achieve more efficient operations.
