Down sampling required to find barcode
Karin Hellqvist posted a topic in Machine Vision and ImagingIn the attached image I have four Code 128 and two Code 39. I have problem detecting them without down sampling the image first. Since I want to grade the bar codes I don't want to down sample since the code quality is reduced then. I noticed this from that sometimes some of the bar codes are found without down sampling an then the grade is higher for those. Down sampling a factor 2 sometimes work, down sampling a factor 4 always works. I have tried croping the image around the bar code but this doesn't help. I'm using IMAQ Read Barcode 2, and have tried to change the parameter Min Bar Width with no result. Is there any other parameter I can change for the algorithm to find the barcodes, without having to down sample my image. Best regards Karin Hellqvist Certified LabVIEW Architect DVel
Change resolution image snaped by gigE camera
ASalcedo posted a topic in LabVIEW GeneralHello to all. First of all thanks a lot for reading this post and being able to help. I have noticed the next problem: My application has a camera, this camera takes images (snap mode) and application process them (detect some edges in the image). It works fine. But when I make the Display bigger my application takes longer to process images (and for me that is crucial). I think that this happens because my application in this case has to process a bigger image (bigger display = bigger image??) So maybe if My camera takes images with lower resolution I solve the problem. So how can I change image resolution captured by my gigE camera? In NI MAX or in Labview? Thanks a lot!
Fit objects in tab control in a lower screen resolution
ASalcedo posted a topic in User InterfaceHello to all. Thanks for helping me. I have developed an application in a laptop of 15.6 inches. Now I am creating a .EXE to deploy in a PLC of 15 inches. All my front panel is a tab control which has controls and indicators inside. The problem is that when I deploy de application I can not see a part of tab control (15 inches vs 15.6 inches). How can I fit tab control to 15 inches easyly? Thanks a lot.
