Embodiment Construction

[0022] A non-rotating insect detection radar based on area imaging lidar includes a plurality of area imaging lidars. The combined detection range of multiple surface imaging lidars is 360°, which is the entire detection plane. The detection range of a single surface imaging lidar is 60°-120°, and a combination of 3 to 6 surface imaging lidars is usually used. In this embodiment, the detection range of a single surface imaging lidar is 90 degrees, so four lidars are used to form a 360° detection range.

[0023] Such as figure 1 As shown, a non-rotating insect detection radar based on surface imaging lidar, including a first smooth imaging lidar 1, a second smooth imaging lidar 2, a third smooth imaging lidar 3, and a fourth smooth imaging lidar Imaging laser radar 4, fixed column 5 and data transmission module 6. The data transmission module 6 is arranged on the top of the fixed column 5; the first optical surface imaging laser radar 1, the second optical surface imaging la...

Abstract

The invention relates to a non-rotary type insect detection radar based on surface imaging laser radars and a method; the non-rotary type insect detection radar comprises a plurality of surface imaging laser radars, a fixed column and a data transmission module; the plurality of surface imaging laser radars are same in structure; the data transmission module is arranged on the top of the fixed column; the plurality of surface imaging laser radars are placed on one horizontal plane, and fixed on the top of the fixed column and below the data transmission module; signals formed by the pluralityof surface imaging laser radars are transmitted to a remote base station or a host computer in real time through the data transmission module. The surface imaging laser radar is in a non-rotary type,and can detect the whole optical surface in a large angle scope, thus realizing faster responses and providing more stable results; the non-rotary type insect detection radar can accurately record theinsect flew over time and positions, can determine the insect types, and is used for quantitatively analyzing the quantity, type and position information of insects flew over the laser radar detectedplane, thus providing data support for the ecology researches.

Description

technical field [0001] The invention belongs to the technical field of insect detection and laser radar, and relates to a non-rotating insect detection radar and a method based on area imaging laser radar. Background technique [0002] Insect pests have the characteristics of large-area migration and have a great impact on crop production. The use of radar, especially lidar for telemetry, can calculate the orientation, height, direction of movement, species and other information of insect migration, which can provide decision-making basis for ecological research on insect habits, control of regional insect populations, and suppression of pest outbreaks. Traditional lidar mainly detects the laser irradiation area at a single angle. The detection range is small. If you need to detect a surface, you need to use the motor to rotate, so the cost is high, the speed is slow, it is easy to damage, and it is easy to miss information. Based on these reasons, this patent proposes a n...
