The invention discloses a method for identifying fruits and vegetables in a complex environment based on computer vision. The method comprises the following steps that firstly, an image of the fruits and vegetables to be identified is obtained; secondly, the obtained image of the fruits and vegetables is pre-processed, and the pre-processed image is divided into a fruit and vegetable area and a background area; the features of the pre-processed image of the fruits and vegetables are extracted, wherein the extracted image features comprise the color features and the texture features; then, the features of the fruits and vegetables are fused through the self-adapting weighting method; finally, the fruits and vegetables are identified through the nearest neighbor sorting algorithm. Compared with an exiting fruit and vegetable identification system, the method for identifying the fruits and vegetables in the complex environment based on the computer vision has the advantages that the algorithm complexity is low, the identification rate is high, a high usability is achieved, and the method can be effectively applied to daily life.
