coordinates

问题 I have a collection of items and some of them may have the same coordinates. As a result they are displayed as 1 marker in Google Maps since the markers are painted one on top of each other. To address this I tried to "move" those markers by a few meters so that the markers do not collide. I would like to move them to a 5 meters from where their location is. I did the following following another SO answer: double newLat = item.getLatitude() + (Math.random() - .005) / 15000; double newLon =

问题 given an image composed of a plain black field with a single white rectangle inside it somewhere, how can i extract the coordinates of the rectangle ? i've googled and googled and found numerous articles on edge detection using hough lines, convolution, morphology, etc., but all of these actually edge the image or convert it in some way. i don't want to change the image, all i want to do is find where the edges are. obviously, i could simply iterate over the entire width+height of the image

问题 As a newbie of pdfbox user, I plan to extract data in a table, but tables with special formats, say with merged column headers should be processed with the help of table's borderlines. Therefore, the coordinates of the text and at least the table's horizontal borderlines should be extracted. In order to extract the text from the table, I used PDFTextStripper to get the list of TextPosition objects; in order to extract the horizontal lines from the same page, I used PDFGraphicsStreamEngine to

问题 I want to map textures with correct perspective for 3D rendering. I am using barycentric coordinates to locate points on the faces of triangles. Simple affine transformation gave me that standard, weird looking result. This is what I did to correct my perspective, but it seems to have only made the distortion greater: three triangle vertices v1 v2 v3 vertex coordinates are v_.x v_.y v_.z texture coordinates are v_.u v_.v barycentric coordinates corresponding to vertices are b1 b2 b3 I am

问题 I got the following code. I'm trying to submit my coordinates to an email. But every time I press the button, the app closes. public LatLng getLocation() { // Get the location manager LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); Criteria criteria = new Criteria(); String bestProvider = locationManager.getBestProvider(criteria, false); Location location = locationManager.getLastKnownLocation(bestProvider); //double lat; //double lon; try { lat =

问题 In C# UWP, how to get current finger holding coordinates on mobile? I have been using this: private void mainGridHolding(object sender, HoldingRoutedEventArgs e) { var coordinateY = e.GetPosition(mainGrid).Y; } But, I don't want to execute it all the time whenever user holding the screen. And also, this event fire after the popup is shown, so I get the wrong informations. Like there is a property for Pointer location: var pointerPosition = Windows.UI.Core.CoreWindow.GetForCurrentThread()

问题 I am trying trying to find a new location(x,y,z) between two already existing locations (x,y,z). e.g. lets say the distance between locA and locB is 2500. locNew should always be the location with distance 300 and should be on the line of locA and locB. I have no issues finding the midpoint between locA and locB, but I keep banging my head trying to find locNew for this specific situation. I tried this, but it returns a point that is not on the line from locA to locB: locA = {x = 400, y = 400

问题 Im facing the next problem: I have an imageView that change the size programmatically because de density hdpi has a 480x800 resolution. I change the size with layoutParams. After I change the size, I want to position the imageView. When I position the view for example to the coordinate (0,0) I saw that between the imageView and the limit of the screen is a little space, like 25 inches. The imageView moves to other place and when I want to position it again to (0,0), the space between the

问题 I have square, I know the X,Y coordinate for the (A,B,C,D) each, coordinate for (E,F,G,H) and the position for the circle inside first box (I,J). so .. I want to find the coordinates for the same circle inside the second box .. base on all the data have. 回答1: You need to find the transform from the first box to the second B=T*A so you need to find T which is a 3x3 matrix if this is on the plane solve the equations as shown on this page http://andrew.gibiansky.com/blog/image-processing/image
