So I would like to use the uniqueID created from datamatrix code as the DOI for every other metadata (e.g. I like the idea of using the codes every time someone take the physical slide.So either as a browser extension or a external tool or else? How do you think this kind of a tool should be included? (include this directly into the elab is impossible because it’s a proprietary system).But why to choose? Just take: “protocolName_userName_timestamp” as the initial sample name and let the user change it afterwards. What should be the name of the sample when added into the database? At this time we only got: protocol name (at least most of the time), user name, a timestamp and in by far the rarest cases we have a project or trial name.How to make the link between the physical world (datamatrix code glued to a slide) and the digital world (database behind the elab) immutable? Because a user can delete and change the datamatrix codes in the database without any security check or version management.In the next step it will check if a digital-sample already exist in the electronic lab book and create a new sample if necessary using the regular API of elab. Save the results as a csv file to push it into the elab using the official API: It checks if the code was already found in a frame before and stores only the unique codes and for sure it also checks if the codes found are valid (e.g. What’s even more interesting is a “real time scanner” function, where it scans a webcam signal to process every code in front of the camera. It can read out the 6 example codes in about 1 s. It tries to read the codes and can mark them: iPhone as a camera on macOS Monterey/Catalina/Mojave requires 3rd party iOS app such as EpocCam.As a first result for TA3 I build a system that reads Datamatrix Codes right from a webcam (either integrated or usb and also independed of the OS) as a batch scan. iPhone as a camera requires macOS 13 Ventura, iOS 16, and iCloud. ![]() Use additional light sources in semi-dark / poorly lit rooms. always ensure that your room is bright to improve scanning results. It is necessary to place the QR code at the correct distance so it appears sharp. iSight camera has no autofocus feature. use the button at the bottom of the screen to switch to the iSight camera. Phone camera significantly improves scanning performance. use your USB-attached webcam /iPhone or phone camera app (EpocCam) to quickly scan QR codes into your computer. *(7 codes limit that can be removed using in-app) Saves all successfully scanned texts in a local database Double click to open in the corresponding app (Safari, Contacts, Mail, TextEdit, FaceTime.) Quickly scan a selected area with the keyboard shortcut CMD+1 (also available from the top menu) Automatic copy to clipboard (enabled in preferences ) Export scanned QR codes / barcodes as CSV text Full-screen barcode scanning (File-> Full-Screen scan, App Icon-> Full-Screen scan) ![]() Scan your clipboard for a QR code / barcode Drag & Drop on the app icon to scan a QR code / barcode Code Scanner - scans QR codes (screen or camera*), scans other 2D barcodes (screen only) Works with iPhone & webcams (EpocCam.) and it natively runs on the new M1 processors. Capture QR codes like you would do on a phone. Use iPhone or webcam (EpocCam.) to capture QR codes. ![]() Capture QR codes like you would do on phone.
