Background
Traditional crops insect pest monitoring system relies on artifical several worms, and not only working strength is big, and the rate of accuracy is low, still can't report in real time, has fallen behind the development level of modern science and technology far away. Although the crop pest image automatic identification technology appearing in recent years can realize the automatic identification and reporting work of crop pests, the accuracy rate is still not high, and the key problem is in insect image taking.
At present, a high-definition camera shooting method is adopted for insect image taking in a crop insect condition monitoring system. Because the insect volume is generally small, even a high-definition camera hardly reflects the detailed characteristics of the insect under the environment of shooting at a certain height from the insect, the accuracy of automatic identification of the insect image is greatly influenced, for example, rice is taken as an example, the body of the brown planthopper is 2.5-4 mm, but the shooting height of the camera is at least more than 150 mm, and the details of the planthopper can be faded.
The problem that the image taking of the small insects is not ideal due to the fact that the shooting lens and the insects have a certain object distance can be solved through the scanner. When the scanner is used for capturing images, the camera is very close to the insects, so that the detailed characteristics of the insects can be embodied, and the accuracy of automatic insect image identification is greatly improved. However, the existing scanners are designed and manufactured in an indoor conventional environment, cannot normally work in an outdoor field high-temperature and humid environment, and are not suitable for outdoor field operation.
Therefore, how to provide a scanning device for insect image capture of an automatic monitoring system for field crop insect pests, which has high accuracy and good imaging effect, is a problem that needs to be solved urgently by technical personnel in the field.
