MATLAB棋盘格角点检测算法转C++实现
以下是使用C语言实现固定分辨率制作棋盘格的示例代码:
```c
#include <stdio.h>
#include <stdlib.h>
#define BOARD_SIZE 8
#define PIXEL_SIZE 50
int main() {
// 计算棋盘格的像素大小
int board_pixel_size = BOARD_SIZE * PIXEL_SIZE;
// 分配内存用于存储棋盘格
unsigned char* board = (unsigned char*)malloc(board_pixel_size * board_pixel_size);
// 填充棋盘格
for (int y = 0; y < board_pixel_size; y++) {
for (int x = 0; x < board_pixel_size; x++) {
int cell_x = x / PIXEL_SIZE;
int cell_y = y / PIXEL_SIZE;
if ((cell_x + cell_y) % 2 == 0) {
board[y * board_pixel_size + x] = 255;
} else {
board[y * board_pixel_size + x] = 0;
}
}
}
// 保存棋盘格为BMP格式文件
FILE* fp = fopen("chessboard.bmp", "wb");
unsigned char bmp_header[54] = {
0x42, 0x4D, 0x36, 0x00, 0x0C, 0x00, 0x00, 0x00, 0x00, 0x00,
0x36, 0x00, 0x00, 0x00, 0x28, 0x00, 0x00, 0x00, 0x08, 0x00,
0x00, 0x00, 0x08, 0x00, 0x00, 0x00, 0x01, 0x00, 0x08, 0x00,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0xC4, 0x0E, 0x00, 0x00,
0xC4, 0x0E, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0xFF, 0xFF, 0xFF, 0x00
};
int file_size = board_pixel_size * board_pixel_size + 54;
bmp_header[2] = (unsigned char)(file_size);
bmp_header[3] = (unsigned char)(file_size >> 8);
bmp_header[4] = (unsigned char)(file_size >> 16);
bmp_header[5] = (unsigned char)(file_size >> 24);
fwrite(bmp_header, sizeof(unsigned char), 54, fp);
for (int y = 0; y < board_pixel_size; y++) {
for (int x = 0; x < board_pixel_size; x++) {
unsigned char color = board[y * board_pixel_size + x];
fwrite(&color, sizeof(unsigned char), 1, fp);
}
}
fclose(fp);
// 释放内存
free(board);
return 0;
}
```
该代码会生成一个大小为8x8的棋盘格,每个格子大小为50x50像素,生成的棋盘格会保存为BMP格式文件,并命名为chessboard.bmp。可以根据需要调整BOARD_SIZE和PIXEL_SIZE来生成不同大小的棋盘格。
