請問 NI Vision 是否有 corner detection(角偵測) 的函式.
類似 :
i. 1988 年Harris-Stephens 角偵測法ii. 1978 年Hessian matrix 角偵測法iii. 2004 年EoH角偵測法iv. 1997 年SUSAN 角偵測法v. 2006 年FAST 角偵測器

Hey Simon,
NI Vision 似乎沒有直接做corner detection的function,
但是有一些間接的 方法可以做到basic corner detector ,
上圖是利用Vision assisant 做的結果圖,你可以看到可以找到左上與右下的角點,
如果是API 你可以用imaqconvolve來達到套用特定kernel的功能,
float kernel[9] = {0,0,0,0,-1,1,0,1,-1};
imaqConvolve(image, image, kernel, 3, 3, 0, NULL)
What do you need our team of experts to assist you with?
Thanks!
We'll be in touch soon!
