The invention relates to a normal texture map generation method and device, a storage medium and electronic equipment, and aims to reduce the calculation amount in the normal texture map generation process so as to more quickly obtain a normal texture map. The method comprises the following steps: for each pixel point on an original image, determining a first pixel point and a second pixel point in different directions of the pixel point; Determining a first vector according to the first pixel point and the pixel point, and determining a second vector according to the second pixel point and the pixel point; Determining a normal vector perpendicular to a plane formed by the first vector and the second vector; And taking the coordinate of the normal vector as the RGB value of the pixel point, and generating a normal texture map corresponding to the original image.
