Converting TrueDepth data to grayscale image produces distorted image

问题 I'm getting the depth data from the TrueDepth camera, and converting it to a grayscale image. (I realize I could pass the AVDepthData to a CIImage constructor, however, for testing purposes, I want to make sure my array is populated correctly, therefore manually constructing an image would ensure that is the case.) I notice that when I try to convert the grayscale image, I get weird results. Namely, the image appears in the top half, and the bottom half is distorted (sometimes showing the

What's the range of the TrueDepth camera?

问题 What's the minimum and maximum distance that the front facing TrueDepth camera can detect? When detecting depth data, if the value returned was normalized to the range 0 to 1, I'd be able to convert it to a grayscale image pretty easily. However, since the values returned are distance in meters, I could easily get a value such as 2.5. Therefore, knowing the theoretical minimum and maximum could help me normalize the values into the range of 0 to 1. Update: Very inaccurate estimates using

How to make a 3D model from AVDepthData?

问题 I’m interested in the issue of data processing from TrueDepth Camera. It is necessary to obtain the data of a person’s face, build a 3D model of the face and save this model in an .obj file. Since in the 3D model needed presence of the person’s eyes and teeth, then ARKit / SceneKit is not suitable, because ARKit / SceneKit do not fill these areas with data. But with the help of the SceneKit.ModelIO library, I managed to export ARSCNView.scene (type SCNScene) in the .obj format. I tried to

Can I require a user to have a True Depth camera to download my app from the App Store?

问题 An app I want to make only makes sense with a TrueDepth camera for ARKit and augmented reality face tracking capability. Can I require a user to have a True Depth camera(iPhone X only right now) to download my app from the App Store? 回答1: No. Apple's mechanism for segregating App Store listings by device capabilities does include a front-depth-camera key. However, that key is not enabled for use by third-party apps , and Apple doesn't include it in the list of device capabilities that third

Save depth images from TrueDepth camera

问题 I am trying to save depth images from the iPhoneX TrueDepth camera. Using the AVCamPhotoFilter sample code, I am able to view the depth, converted to grayscale format, on the screen of the phone in real-time. I cannot figure out how to save the sequence of depth images in the raw (16 bits or more) format. I have depthData which is an instance of AVDepthData . One of its members is depthDataMap which is an instance of CVPixelBuffer and image format type kCVPixelFormatType_DisparityFloat16 . Is
