The invention discloses a crop hyperspectral image monitoring device, which comprises a base, a control chip and a plurality of indication columns; the indication columns are uniformly distributed onthe base in a rectangular array, the control ends of the plurality of indication columns are connected with the control chip, and each indication column comprises a transparent cylinder, a first indication lamp, a second indication lamp, a first hydraulic rod and a second hydraulic rod; the lower ends of the transparent cylinder, the first hydraulic rod and the second hydraulic rod are fixedly connected with the base, two vertical through grooves are formed in the side wall of the transparent cylinder, the first hydraulic rod and the second hydraulic rod are located on the outer sides of the through grooves respectively, the first indicator lamp is fixedly connected with the telescopic end of the first hydraulic rod, and the second indicating lamp is fixedly connected with the telescopic end of the second hydraulic rod. By means of the two layers of indicator lights sliding up and down on the transparent cylinder, a 3D display structure can be achieved according to specific images, omnibearing monitoring images of crops can be visually displayed conveniently, meanwhile, colorful images are displayed through the color-changing LED lamps, and the colors of the crops are further displayed.
