奇怪的现象

with 2 comments

在不同物距标定光心,竟然晃动能有40-50pixel,图像的尺寸是2820×1876.
检查了数据好几遍,算法的稳定性挺好的,稍微有点噪声抖动在10pixel以内。直接看数据光心也确实是动了。

不同的物距,magnification 和distortion的弯曲度也是不一样,这倒是不奇怪。

camera control的几个trick

with one comment

在拍照前要确保写进去的新文件原来不存在,也就是不能overwrite
因为overwrite速度会偏慢,然后程序又送新的命令进去,camera太busy了整个控制程序就崩溃了…

单纯refocus不拍照需要打开liveview,否则不work…

用的program基本和canon sdk给的那个例子一样
