Embodiment Construction
[0035] In conjunction with the accompanying drawings, the block diagram of the human eye positioning and human eye state recognition method proposed by the present invention is as shown in Figure 1, and the specific implementation steps are as follows:
[0036] Step 1: face image preprocessing;
[0037]Step 2: Coarse positioning of human eyes;
[0038] Step 3: Precise positioning of the human eye;
[0039] Step 4: Human eye state recognition.
[0040] Wherein the specific implementation steps of Step 1 are:
[0041] The first step is to grayscale the face color image after positioning;
[0042] The camera collects color images with R, G, and B components. Based on the needs of subsequent image processing, the color images need to be converted into grayscale images. The color of each pixel in the grayscale image only has 256 grayscale levels from black to white, and there is no color. The conversion format is as follows: v=0.259R+0.587G+0.144B; where v represents the conver...
