The invention discloses a method and equipment for continuously detecting oranges and tangerines based on multispectral structured light, and belongs to the technical field of optical detection of agricultural products. Citrus is scanned based on linear array structured light to generate a spectrogram, a color map is generated based on visible light, and the spectrogram and the color map are subjected to pixel point mapping based on a reflection element. The spectrograms of the upper part and the lower part of the citrus are matched based on the characteristics of the citrus navel and the stem, and a complete three-dimensional spectrogram is formed. Pixel filling is carried out on the three-dimensional spectrogram in combination with pixel point mapping and the color image to form a complete orange-shaped three-dimensional color image. According to the invention, the coverage area of the linear array structured light is improved by adjusting the distance between the adjacent detection stations, and the accura
