X Ray Scanner Camera
Alexina Jurs
Hello! I am building an application - scavenger hunt for a museum. It contains various quests. Some of them use personal image classifier and others qr code scanner. So, when i run the first 2 quests which require scanner it works perfectly. Then two image classification quests follow and after that another scanner quest. And here comes the problem. When i call the third qr scanner do scan, it shows black screen with message "Scanner: Camera framework bug". After a long time of tries I am almost sure that it has to do with personal image classifier. But still not sure. Anyone with similar problem? Thank you in advance.
to test it when load press button "φωτογράφισε το" and take photo of the picture with the door i have uploaded. when you do this correctly then in the next page press the button "σκαναρε" and scan the picture with the qr code. if it works normally it will let you scan it otherwise it will show the message "scanner: camera framework bug" which shows to me.
Thank you for the directions. "scanner: camera framework bug" does NOT appear.
I got three 'matches'; one about 30% next about45% then finally 75% . Then the app went to a screen with a soldier with a sword.
Oh sorry forgot to mention the page with the soldier. I finally found a way to fix both of the problems by changing the code. i added "camera" block and then changed some blocks

Replication: Deconstructing, lets say only by 1 percent, then reconstructing a scanner room spawns 2 drones as it should, but any old drones floating around outside of the room stay, allowing the player to duplicate as many drones as they want
It works, but here's what I want to do:The user can navigate between screens, one of them being a QR code scanner.While scanning, I need to debounce the scanner so it doesn't keep generating onRead events. The user could a) start a scan in the scan screen without reading a QR code and navigate manually to another screen.b) read a QR and automatically move to another screen for processing, then go back to scan again.For this reason I need to re-enable the scanner after some reasonable time.I can't just set reactivate to false because then the QR scanner is inactive until I restart the app.The problem is that when the user stays in Another screen, the QR scanner re-activates after the timeout and tries to scan when it is not desired. What I ideally would like to do is to deactivate the QR scanner while the user is not in the scan screen, and re-activate it with the above mentioned parameters whenever the user enters the scan screen.Is there any way to do this? Thanks!
For example, If I scan 35mm black and white films with these devices, can I get the quality that rivals a Flextight scanner?
I am particularly curious about the sharpness and gradation(tonal transitions) quality.
We currently run 3 Square registers and 2 ipads for our retail store. I love the Square smartphone app. However, as far as I can tell, it's missing a feature that it really needs. I would like to be able to scan barcodes with an android smartphone CAMERA (like you can with the ipad app). Am I missing something or is this feature not available? I do understand I can connect a bluetooth barcode scanner but that's not what I want to do. Thank you!
Ryan Kojima tells PetaPixel that his project is not new and first built the Frankenstein camera 10 years ago. However, he has extracted more and more performance from it, recently capturing a 514-megapixel image.
They appear in all of my fluorescence channels and at many z-positions, and in live view they seem to fade in and out so that sometimes the sample looks normal. Others have had this problem occasionally before on our scope, and closing and restarting LAS X fixed it in the past, but neither restarting the software alone nor turning off the microscope, scanner, lamp etc. and trying again a few hours later is fixing the problem for me now. I also have had this happen before in the first slice of a z-stack but not in the others, whereas now it is happening in many slices. Any advice on what this is or how to fix it is much appreciated!
As the name implies, laser scanners have a scan head that passes over the gel or membrane section by section. The light is detected as the scan head moves to produce the individual pixels of the image.
CCD camera-based imaging, on the other hand, works by detecting the entire sample at once, either with chemiluminescence or fluorescence. Varying the exposure time can improve detection or reduce noise.
Laser scanners, can image at near-infrared wavelengths and perform phosphorimaging. These features make it possible to detect light at longer wavelengths than systems that only work in UV or visible light, and detect signal from radioisotopes.
Protein detection using a laser scanner lets you carry out high-throughput analysis of even the lowest protein levels (as low as 3 pg). Laser systems can have a linear dynamic range of more than five orders of magnitude and typically a resolution of around 10 µm.
Fig 2. Components of a typical CCD camera-based imaging device. The sample can be illuminated in a variety of ways depending on the nature of the labels to be analyzed. The sample is then viewed by the camera. The camera includes focusing optics to accommodate samples at different heights. Emission filters can be inserted in the light path to select specific wavelengths and significantly reduce background.
Again, basic usage of QR code is (least for my case) that we generate Virtual Column where we construct the dynamic URL to generate the qr and display it as Image. The variable within the URL is basically IDs for the row in question.
Then attach action for LINKTOVIEW expression. The user captures the QR code and it is convered to text, i.e. it will capture the IDs for the row. Then pass that value to the linktoview action. By doing so, user will scan the code and without saving it, the user will be prompted to the targed view easily. It works perfect. However, some of my clients gave me a feedback, it is troublesome. They dont want to open the appsheet app for scan. They just want to open their camera over the mobile phone (cell phone in US term?) and scan the code. Then the Appsheet app to open up to display the target view.
And set the data type to Image. It is possible Thumbnail type may work, but sometime the scanner will not recognize the strings propertly with the tiny QR code, so better to stay with image type as my suggestion.
On IOS, when QR code is found by the camera, tapping on the link, it will launch APPSHEET, IOS will omit part of the string, deletes anything after the APP ID, it would take you to any part of the app, not the intended view.
The Instant Scan Adapter V2 helps you to scan your Polaroid 600, SX-70, and i-Type images easily, efficiently, and completely eliminates the dreaded Newton rings that usually come when scanning polaroids on a flatbed scanner. This Scan Adapter is *also* able to accommodate Fuji Instax Wide and Fuji Instax Square images.
Since the Code Scanner is a separate camera output (just like photo or video), it cannot be attached simultaneously with photo and video enabled.You need to disable either photo, video, or the codeScanner.
However those of us familiar with using a flatbed scanner for scanning negatives know that sometimes it really can take a lot of time going through even one roll of film if you want or need to make the necessary corrections to get the best out of the images.
4) Put other roll of tape on top of the film and position the image you want to scan. This might require some moving around as most of the cameras on our phones are not placed in the center of the phone itself. The tape roll also acts as support to keep the phone steady.
Firstly thanks for helping. When I rotate the phone camera show a little bit. But I could not show on using transparency. I recorded my phone screen while rotating phone .I stop the video and take a screenshot. When I rotate, camera was showing behind the app
Windows XP users can use the PTP (Picture Transfer Protocol) function. The PTP function allows you to download JPEG images stored on a CF card in the camera to your computer without having to start the software provided on the SOLUTION DISK.
