4p-在一张图片中根据矩形四个点的坐标计算两个矩形是否相交
使用场景:勾选框提取字段值等。
def mat_inter(box1, box2): # box1,box2是否相交 x01, y01, x02, y02 = box1 # (x01,y01),(x02,y02) 对角线的点坐标 x11, y11, x12, y12 = box2 lx = abs((x01 + x02)/2 - (x11 + x12)/2) ly = abs((y01 + y02)/2 - (y11 + y12)/2) sax = abs(x01 - x02) sbx = abs(x11 - x12) say = abs(y01 - y02) sby = abs(y11 - y12) if lx <= (sax + sbx)/2 and ly <= (say + sby)/2: return 1 else: return 0
