我在两个角之间绘制了2条线，如果两条线之间的距离越来越近，我想将它们合并。但是问题是线条不是笔直的，因此，如果尝试将它们合并，则最接近的角落将合并，而另一侧则不是。例如，第1行和第2行的结束角彼此之间的距离更近，而开始角则没有。想知道您的意见。代码如下：
def mergeLineCorners(wallLines, _MERGE_TOLERANCE = 15):
for i in range(len(wallLines)):
lineA = wallLines[i]
for j in range(len(wallLines)):
lineB = wallLines[j]
if distance(lineA[0]['x'],lineA[0]['y'], lineB[0]['x'],lineB[0]['y']) < _MERGE_TOLERANCE: #A start B start
mid_x = float(lineA[0]['x'] + lineB[0]['x']) / 2
mid_y = float(lineA[0]['y'] + lineB[0]['y']) / 2
wallLines[i][0]['x'] = mid_x
wallLines[i][0]['y'] = mid_y
wallLines[j][0]['x'] = mid_x
wallLines[j][0]['y'] = mid_y
if distance(lineA[0]['x'],lineA[0]['y'], lineB[1]['x'], lineB[1]['y']) < _MERGE_TOLERANCE: #A start B end
mid_x = float(lineA[0]['x'] + lineB[1]['x']) / 2
mid_y = float(lineA[0]['y'] + lineB[1]['y']) / 2
wallLines[i][0]['x'] = mid_x
wallLines[i][0]['y'] = mid_y
wallLines[j][1]['x'] = mid_x
wallLines[j][1]['y'] = mid_y
if distance(lineA[1]['x'], lineA[1]['y'], lineB[0]['x'], lineB[0]['y']) < _MERGE_TOLERANCE:
mid_x = float(lineA[1]['x'] + lineB[0]['x']) / 2
mid_y = float(lineA[1]['y'] + lineB[0]['y']) / 2
wallLines[i][1]['x'] = mid_x
wallLines[i][1]['y'] = mid_y
wallLines[j][0]['x'] = mid_x
wallLines[j][0]['y'] = mid_y
if distance(lineA[1]['x'], lineA[1]['y'], lineB[1]['x'], lineB[1]['y']) < _MERGE_TOLERANCE:
mid_x = float(lineA[1]['x'] + lineB[1]['x']) / 2
mid_y = float(lineA[1]['y'] + lineB[1]['y']) / 2
wallLines[i][1]['x'] = mid_x
wallLines[i][1]['y'] = mid_y
wallLines[j][1]['x'] = mid_x
wallLines[j][1]['y'] = mid_y
return wallLines
从JSON文件传入的角和第1行的xy位置，例如第1行：x：330，y：530。和第2行。x2：330，y2：570
左侧是第1行，右侧是第2行 the output result after draw lines
如您所见，结束角已合并，但起点未合并。因为line2不像line1那样笔直
