The invention discloses an
agricultural machinery label identification method based on an image, and relates to the technical field of
label identification, and the method comprises the steps: obtaining an original image of an
agricultural machinery label, carrying out the
image enhancement preprocessing of the original image, inputting the enhanced image into a
text detection network based on adaptive Bezier curve regression, and carrying out the recognition of the
agricultural machinery label. And obtaining a preliminary
text recognition result, performing
verification, error correction and formatting conversion, generating a key-value pair data packet, and uploading the key-value pair data packet to a
remote management platform. According to the method, illumination unevenness and background interference are inhibited through
image enhancement preprocessing, the low-contrast character edge definition is improved, a character detection network of adaptive Bezier curve regression is adopted, a deformed text area is accurately fitted, robust detection of the agricultural machinery sign under the complex background is achieved, and the method is suitable for popularization and application. According to the method, the Bessel feature alignment and lightweight attention decoding mechanism are combined, the
processing efficiency is improved while the recognition precision is ensured, then
verification and error correction are performed by using a structured rule and a
semantic knowledge base, the accuracy of
text recognition is improved, and data are output.
