Abstract

The invention provides an automatic intelligent obstacle avoidance design method for seismic exploration. The automatic intelligent obstacle avoidance design method for seismic exploration comprises the following steps: step 1, acquiring a ground object marking map and a satellite picture in a work area range; step 2, extracting obstacle information and a corresponding satellite picture pixel value in the ground object marking map, and constructing a training sample library of different obstacles; 3, performing neural network training on the sample library to obtain neural network model parameters; step 4, automatically identifying satellite pictures in the whole work area range; and step 5, carrying out automatic obstacle avoidance on a shot point according to the identification result. According to the seismic exploration automatic intelligent obstacle avoidance design method, the mapping relationship between the ground object marking information and the corresponding satellite picture pixel value is trained through the neural network; and then obstacle automatic identification and classification are performed on the whole work area satellite picture through the trained neural network so that the problem of the identification and classification of various obstacles in the satellite picture can be well solved.

Description

technical field [0001] The invention relates to the field of oil and gas seismic exploration data acquisition, in particular to an automatic intelligent obstacle avoidance design method for seismic exploration. Background technique [0002] Observation system design plays an important role in seismic data acquisition, and indoor observation system design can usually be carried out according to the geological requirements of exploration. Usually, the indoor observation system design does not consider the obstacle distribution in the actual construction area, which results in differences between the actual construction and the designed observation system. In order to design an observation system that is more in line with the actual situation, indoors can also design a variable observation system through satellite maps to avoid common obstacles such as buildings, factories, villages, and waters. At present, the design of obstacle avoidance is mainly through manual adjustment, ...
