使用Python编写的示例代码-ObjectDetectionProtos中anchor_generator_pb2生成随机锚点

发布时间：2023-12-11 12:00:13

import random

from anchor_generator_pb2 import AnchorGeneratorGridCells, AnchorGenerator

# 生成随机锚点的函数

def generate_random_anchors(grid_size, num_anchors):

anchor_generator = AnchorGenerator()

for _ in range(num_anchors):

grid_cell = AnchorGeneratorGridCells()

for _ in range(grid_size):

anchor_x = random.random() # 随机生成锚点横坐标

anchor_y = random.random() # 随机生成锚点纵坐标

grid_cell.anchor_x.append(anchor_x)

grid_cell.anchor_y.append(anchor_y)

anchor_generator.grid_cells.append(grid_cell)

return anchor_generator

# 使用例子

grid_size = 5 # 网格大小

num_anchors = 10 # 锚点数目

anchors = generate_random_anchors(grid_size, num_anchors)

print(anchors)
