I think I know what you are asking for. Here is what you can do. first get the height of the person say h meters. if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android … Read more
Combining a few answers into a more digestible one because @VP’s answer, while technically clear, is difficult to understand if it’s your first time moving from Camera to Camera2: Using https://github.com/googlesamples/android-Camera2Basic as a starting point, modify the following: In createCameraPreviewSession() init a new Surface from mImageReader Surface mImageSurface = mImageReader.getSurface(); Add that new surface as … Read more

Besides the solution using the FileProvider, there is another way to work around this. Simply put StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder(); StrictMode.setVmPolicy(builder.build()); in Application.onCreate() method. In this way the VM ignores the file URI exposure.
As said before you need to find the correct preview size (the one with aspect ratio 1:1) and probably you have to use FrameLayout for the SurfacePreview. It seems that you have and aspect ratio problem maybe you have the right preview size but you are placing it in an incorrect layout. Another solution might … Read more
I accept the question has been answered adequately (with the obvious caveats of requiring level ground and possible accuracy problems) but for those who don’t believe it can be done or that it needs a video camera, let me explain the low-level math needed to do it…. The picture above shows me standing outside my … Read more
Updated to Swift 4 Hi it’s really easy to use AVCapturePhotoOutput. You need the AVCapturePhotoCaptureDelegate which returns the CMSampleBuffer. You can get as well a preview image if you tell the AVCapturePhotoSettings the previewFormat class CameraCaptureOutput: NSObject, AVCapturePhotoCaptureDelegate { let cameraOutput = AVCapturePhotoOutput() func capturePhoto() { let settings = AVCapturePhotoSettings() let previewPixelType = settings.availablePreviewPhotoPixelFormatTypes.first! let … Read more
As of 2017, WebKit announces support for WebRTC on Safari Now you can access them with video and standard javascript WebRTC E.g. var video = document.createElement(‘video’); video.setAttribute(‘playsinline’, ”); video.setAttribute(‘autoplay’, ”); video.setAttribute(‘muted’, ”); video.style.width=”200px”; video.style.height=”200px”; /* Setting up the constraint */ var facingMode = “user”; // Can be ‘user’ or ‘environment’ to access back or front … Read more
This code snippet will get the latest image from the camera roll (iOS 7 and below): ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; // Enumerate just the photos and videos group by using ALAssetsGroupSavedPhotos. [library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop) { // Within the group enumeration block, filter to enumerate just photos.
