英文摘要：

According to the construction needs of the smart city wireless video sensor network, a three-valued quantum genetic algorithm is proposed for solving the deployment problem of optimized network coverage algorithm. The monitoring region is depicted by two-dimensional discrete grid model, and the discrete grid model is represented by a code description matrix. The directional wireless video sensor is described by a seven-tuples. The three-valued quantum genetic algorithm with reasonable chromosome coding and optimized three-valued quantum rotation gate parameter is used to search the solution space, which has a good convergence rate and a fast computation speed. Two limit values of ideal coverage rate and ideal weighted coverage rate are introduced to evaluate the algorithm by the way of relative comparison. The result of simulation experiments show that the node deployment solutions worked out by the algorithm can well approximate the ideal limit value.
