A tactile sensing device for identifying the amount of partial planting of rice plants

Abstract

The invention relates to a device for identifying deflection of rice plants by tactile perception, which comprises an upper casing, a lower casing, a tactile perception system, a data processing system, a profiling rod and a power source. The upper casing and the lower casing are sealingly connected, the profiling rod is fixed on the upper casing, and the power source and the data processing system are installed in the lower casing. The tactile perception system comprises two sets of bending sensors before and after, wherein the two bending sensors in each set are symmetrically mounted on theleft and right sides of the lower casing, and the bending sensors extends in the left and right direction. According to the deformation response law of the bending sensor, the tactile perception system realizes the identification and localization of the rice plants through the data processing system, and on this basis, the statistics of the planting amount of the rice plants are completed. According to the device for identifying deflection of rice plants by tactile perception, the deflection of rice plants between adjacent rice plants is calculated, and further the corresponding regulation ofthe weeding parts is guided to realize the weeding operation of the seedling avoidance machine, and the invention belongs to the field of crop identification.

Description

technical field [0001] The invention relates to the field of field crop identification, and particularly discloses a tactile sensing rice plant offset identification device. Background technique [0002] In the field of agricultural weeding, due to the increasing public attention to food safety, mechanical weeding is becoming a key technology for the sustainable development of agriculture and the cultivation of "green food". At present, the technical difficulty in the field of mechanical weeding research mainly lies in how to reduce the damage rate of rice seedlings. Improving the planting uniformity of crops and the identification and positioning technology of crops are one of the important ways to solve the difficulties. Foreign crops are mainly grown in dry land, mechanized planting has good stability, the amount of crop partial planting is small, and the effect of mechanical weeding is ideal. However, a large part of my country's crops grow in paddy fields. The differen...

Problems solved by technology

However, the background of the rice growth environment is complex, the water surface is reflective, the top leaf crowns between adjacent rice holes (plants) have been partially covered by each other during the weeding period, and the grass weeds are similar in shape to rice, so it is very difficult to identify crop rows based on machine vision
