Automatic Detection Method of Field Flying Pests Based on Machine Vision

Accurate statistics of pest number is of great importance to comprehensive pest management.It is difficult to calculate flushing away pests by traditional method of statistical pest which is to count number of pests on fixed plant.Place sticky board to catch insects and automatically identify in a fixed position，recognition in the normal life habit of pests，which could effectively solve problems of inaccurate statistics and inaccurate information of flying pests.At the same time，methods of automatic threshold segmentation，target adhesion processing，target recognition and biological feature interference removal were adopted to effectively calculate number of insect pests in the field.Recognition accuracy was above 85%，which provided basis for pest control.
