如何从 Opencv lines 函数正确加入折线

Question

我正在尝试使用 opencv lines 函数复制我在 示例图像 上的内容。我已经能够在目标图像上画线了，但是线断了，

我想对齐虚线，以便它们可以显示为示例图像，请问我该如何实现。

下面是我用虚线输出的图像。

我的示例代码。

results = hr['matchedPoints1'].values.tolist()
results2 = hr2['matchedPoints2'].values.tolist()

for i in zip(results, results2):
    color = tuple(np.random.randint(0,255,3).tolist())
    (x1, y1), (x2, y2) = i
    print( (x1, y1), (x2, y2))
    cv2.line(img1, (x1,y1), (x2,y2),(255,255,255), 2)

    
img1 = cv2.cvtColor(img1,cv2.COLOR_BGR2RGB)

plt.subplot(121),plt.imshow(img1)
plt.show()

Answer 1

每组点对于相应的图像都是唯一的。

我已经展示了如何使用 MatchedPoints1:

获取第一张图像的可视化效果

MatchedPoints1 = [(89.6214953271028,368.64953271028),
(39.3785046728971,384.200934579439),

(269.060747663551,318.406542056075),
(269.060747663551,301.658878504673),
(632.724299065421,209.546728971963),
(587.266355140187,138.967289719626),
(578.892523364486,80.3504672897196),
(571.714953271028,128.200934579439),

(211.640186915888,189.210280373832),
(193.696261682243,240.64953271028),
(194.892523364486,264.57476635514),
(103.976635514019,292.088785046729),
(135.079439252336,331.565420560748)]


img = cv2.imread('house.png')
img2 = img.copy()

for e, i in enumerate(MatchedPoints1):
  color = tuple(np.random.randint(0,255,3).tolist())
  if (e < (len(MatchedPoints1) - 1)):
    img2 = cv2.line(img2, (int(i[0]), int(i[1])), (int(MatchedPoints1[e+1][0]), int(MatchedPoints1[e+1][1])), color, 2)
    img2 = cv2.circle(img2, (int(i[0]), int(i[1])), 5, color, -1)

结果：

The same can be done for the second image using MatchedPoints2.
