Data acquisition based on existing drawings is an important part of basin modeling.But the digital acquisition faces the trade-off between efficiency and accuracy.Combining the target detection and Particle Swarm Optimization (PSO) technique,an improved Snake curve extraction algorithm based on particle density was proposed.The algorithm maintained a certain distance between particles to avoid the premature of PSO algorithm,and optimized convergence speed by modifying the model parameters.Compared with the traditional PSO algorithm,the experimental results show that the proposed algorithm is efficient,and has been applied in practical project.
