Embodiment 1
[0174] Example 1. At the beginning of 2018, most areas of Qianwei County, Sichuan Province encountered a relatively severe drought, which had a negative impact on the production of rapeseed. Rapeseed agricultural insurance in some areas of Qianwei County is underwritten by the insurance company. There are 18 townships in the area covered by the insurance company, mainly located in the area east of the Minjiang River. In the stage of insurance claims, the degree of rapeseed production reduction is a key basis for claims. Accurately grasping the extent of the disaster, according to the conventional statistical method of rapeseed production, requires a lot of labor costs, and the statistical results are also affected by various uncertainties such as human interference, which weakens the reliability and accuracy of the results .
[0175] The project team, together with colleagues from the third-level institutions and the staff of the township government, conducted a preliminary s...

The invention discloses a crop scientific yield measurement method and system. The crop scientific yield measurement method comprises the following steps: preprocessing an acquired satellite image; identifying the preprocessed satellite image through a convolutional neural network model; processing the identification result, and calculating by combining the identification result with GIS geographic information to obtain data information of the vegetation planting area; calculating the vegetation index grade of each planting area and the proportion of each vegetation index grade in each planting area; and calculating the yield of each vegetation grade in each planting area. Multiple key data such as the rape planting area and distribution and the predicted yield of rapes can be efficientlyand accurately determined, and scientific data support is provided for claim settlement. The labor cost is reduced, the statistical result is prevented from being greatly interfered by human factors and other uncertain influences, and the reliability and accuracy of the statistical result are improved.
Description
technical field [0001] The invention relates to the field of crop yield measurement, in particular to a method and system for scientific yield measurement of crops. Background technique [0002] With the development of society, more and more people realize the importance of insurance. Most of the insurances are insured for themselves or their families; however, there are also some special insurance policies, such as insuring the output of their own crops, Guaranteed that if encountering natural disasters, the yield of crops (such as rapeseed) will drop sharply and cause great economic losses. [0003] In the stage of insurance claims, the degree of rapeseed production reduction is a key basis for claims. Accurately grasping the degree of disaster damage is an important data proof for subsequent claims settlement. Therefore, how to accurately, quickly and efficiently measure the degree of damage to crops is a problem that needs to be solved at this stage. Contents of the i...
