HOperatorSet.Connection 有内存泄漏或缓存

开发环境

Win7 VS2002 halcon12，直接运行Debug的exe

宽高5000，单格1*1的棋盘占用内存

手动释放region regionConnect

private void butTemp_Click(object sender, EventArgs e)

{

butTemp.Enabled = false;

HOperatorSet.SetSystem("clip_region", "false");

{

HObject region;

HOperatorSet.GenCheckerRegion(out region, 5000, 5000, 1, 1);

HObject regionConnect;

HOperatorSet.Connection(region, out regionConnect);

region.Dispose();

regionConnect.Dispose();

}

butTemp.Enabled = true;

}

大约占用200M，两者的顺序不影响结果。

都不释放

private void butTemp_Click(object sender, EventArgs e)

{

butTemp.Enabled = false;

HOperatorSet.SetSystem("clip_region", "false");

{

HObject region;

HOperatorSet.GenCheckerRegion(out region, 5000, 5000, 1, 1);

HObject regionConnect;

HOperatorSet.Connection(region, out regionConnect);

//region.Dispose();

//regionConnect.Dispose();

}

butTemp.Enabled = true;

}

大约占350M

只释放region

private void butTemp_Click(object sender, EventArgs e)

{

butTemp.Enabled = false;

HOperatorSet.SetSystem("clip_region", "false");

{

HObject region;

HOperatorSet.GenCheckerRegion(out region, 5000, 5000, 1, 1);

HObject regionConnect;

HOperatorSet.Connection(region, out regionConnect);

region.Dispose();

//regionConnect.Dispose();

}

butTemp.Enabled = true;

}

大约占用200M

只释放regionConnect

private void butTemp_Click(object sender, EventArgs e)

{

butTemp.Enabled = false;

HOperatorSet.SetSystem("clip_region", "false");

{

HObject region;

HOperatorSet.GenCheckerRegion(out region, 5000, 5000, 1, 1);

HObject regionConnect;

HOperatorSet.Connection(region, out regionConnect);

// region.Dispose();

regionConnect.Dispose();

}

大约占用200M

其它版本

换了halcol18 halcon12的 debug release都如此。

先释放regionConnect和先释放region 都如此。
