Abstract

The invention discloses a method for rapidly measuring insect ascending and descending rate based on Radon transformation. The method for rapidly measuring insect ascending and descending rate based on Radon transform comprises: performing binarization processing on the data matrix to obtain binarization processing After the data matrix, the data matrix after the binarization process is carried out linear Radon transformation, thereby transforming into the parameter domain, detecting the peak value of the parameter domain, extracting the parameter domain coordinates corresponding to the peak value of the parameter domain, according to the The corresponding relationship between the coordinates of the parameter domain and the slope of the target track, and the corresponding relationship between the slope of the target track and the rate of ascent and descent of the target are calculated to obtain the rate of ascent and descent of the target track in the data matrix. The invention extracts the slope of the straight line contained therein by detecting the peak value of the parameter domain, and quickly realizes the measurement of the insect ascending and descending rate. The invention provides an effective and fast measuring means for the measurement of the insect ascending and descending rate.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a method for rapidly measuring the rate of rise and fall of insects based on Radon transformation. Background technique [0002] Numerous insects, especially locusts, rice planthoppers, meadow borers and other pests migrate at night on a large scale and often bring serious economic losses to the places where they migrate. However, traditional optical equipment has limited observation capabilities at night, and radar is used as a long-distance detection tool. , can realize all-day and all-weather monitoring of the target airspace, provides a new method for observing airborne insect swarms, and plays an irreplaceable role in the study of insect migration. [0003] The rate of insect ascent and descent is an important indicator to reflect the direction and speed of insect movement during migration. The insect ascent and descent rate measurement algorithm in the prior art is mainly ba...
