从路径拼接图片 - ImageStitchFromPath ​

函数简介 ​

从目录批量读取图片并进行拼接，可返回拼接轨迹数据。

接口名称 ​

ImageStitchFromPath

DLL调用 ​

int64_t ImageStitchFromPath(int64_t instance, char* path, int64_t* trajectory);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
path字符串图片目录（如 C:/imgs/）
trajectory长整数型指针输出参数，可为0；返回轨迹数据的字符串指针

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.ImageStitchFromPath("C:\\test.txt", "value");
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long handle = ola.ImageStitchFromPath("C:\\test.txt", "value");
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
handle = ola.ImageStitchFromPath("C:\\test.txt", "value")
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long handle = ola.ImageStitchFromPath("C:\\test.txt", "value");
cpp
var ola = com("OlaPlug.OlaSoft")
var handle = ola.ImageStitchFromPath("C:\\test.txt", "value")
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
handle = ola.ImageStitchFromPath("C:\\test.txt", "value")
text
.局部变量 ola, OLAPlug
ola.创建 ()
handle ＝ ola.ImageStitchFromPath("C:\\test.txt", "value")
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var handle = ola.ImageStitchFromPath("C:\\test.txt", "value");
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 handle = ola.ImageStitchFromPath("C:\\test.txt", "value")
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.ImageStitchFromPath("C:\\test.txt", "value");

原生 DLL 调用 ​

cpp
ImageStitchFromPath(instance, "C:\\test.txt", 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int ImageStitchFromPath(long ola, string path, int trajectory);

ImageStitchFromPath(instance, "C:\\test.txt", 0);
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
ola.ImageStitchFromPath(instance, "C:\\test.txt", 0)

返回值 ​

长整数型：返回拼接后的图像句柄，失败返回0。

注意事项 ​

  • 轨迹数据指针需调用 FreeStringPtr 释放内存。
  • 返回的图像需调用 FreeImagePtr 释放内存。
