The invention relates to the technical field of
food processing, and discloses an intelligent stir-frying control method and
system based on sour soup hotpot condiment, and the method comprises the steps: obtaining real-time image data in the stir-frying process of the sour soup hotpot condiment, and segmenting the real-time image data into reaction sub-region nodes; obtaining gray values and local texture entropies of nodes of the reaction sub-regions, mapping the gray values and the local texture entropies into virtual
elevation data, and constructing a three-dimensional topological geomorphic curved surface of the liquid level; calculating geodesic
path cost between adjacent reaction sub-region nodes on the three-dimensional topological geomorphic curved surface, constructing a geometric connected graph, and clustering the reaction sub-region nodes to obtain
browning clusters; and calculating the
turning radius of the maximum connected subgraph, identifying a
phase change critical point based on the
turning radius and the
browning cluster, and generating a stir-frying equipment control instruction. According to the method, nonlinear transition of the topological structure is captured by using the
gyration radius and
percolation characteristics of the maximum connected subgraph, the critical point of the
Maillard reaction is accurately locked from the perspective of geometric evolution, and the monitoring sensitivity in the heterogeneous fluid environment is improved.
