The invention relates to the technical field of
computer vision and image recognition, in particular to an image recognition method based on
edge computing, which comprises the following steps: dynamically capturing an original image through a plurality of edge nodes, rejecting redundant regions through a multi-
modal perception triggering mechanism, and establishing a cooperative
processing group. Illumination
equalization,
noise filtering and resolution self-
adaptive compression tasks are distributed according to dynamic role election, a standardized preprocessed image is generated, a lightweight
convolutional neural network is operated in parallel to extract a dual-channel
feature vector, and after entropy coding
lossless compression and equipment identity tag and
time sequence stamp attachment, the dual-channel
feature vector is transmitted to a cloud end by adopting a lightweight
encryption protocol. The cloud end analyzes the data packet, reconstructs a feature
topological graph based on space-time relevance, loads a depth residual error recognition model to execute
feature fusion and classification decision, feeds back and updates the weight of an
edge node model, solves the problems of low collaborative efficiency and feature
distortion, and improves the efficiency and precision of image recognition.
