是什么导致此图像中使用opencv-py生成的条带

我正在尝试使用opencv制作一种波长图像。在大多数情况下,我都做对了,除了一些会在图像中产生条纹​​的平滑性问题

这是代码

#make ChroMAX torus
#diametre of torus
dia = 1000
#size of steps to circle torus
degstepsize = 360 / dia * pi
#number of steps
degstepno = int(360 / degstepsize)
#a third of degstepno
third = int(degstepno / 3)
#number of steps for 255 in a third
colstep = 255 / third

#making base colour ring
baseCol = []
#blue to green sector
for i in range(third):
    baseCol.append((int(colstep * (third - i)),int(colstep * i),0))

#green to red
for i in range(third):
    baseCol.append((0,int(colstep * (third - i)),int(colstep * i)))

#red to blue
for i in range(third):
    baseCol.append((int(colstep * i),0,int(colstep * (third - i))))

baseCol = tuple(baseCol)

torus = np.ones((degstepno,100,3), np.uint8) * 30

for i in range(len(torus)):
    for y in range(100):
        torus[i,y] = baseCol[i]

gui.add(cv2imgload(torus),'Torus')
gui.update()

这是图片:

Image with banding

最终,图像将被包裹成甜甜圈。我用圆环的周长而不是360度划分圆环的原因是,我可以确保填充每个像素,因为圆环将从中心抽出(我不确定您是否会理解)
