indoor-positioning-system

问题 I am trying to create an android smartphone application which uses Apples iBeacon technology to determine the current indoor location of itself. I already managed to get all available beacons and calculate the distance to them via the rssi signal. Currently I face the problem, that I am not able to find any library or implementation of an algorithm, which calculates the estimated location in 2D by using 3 (or more) distances of fixed points with the condition, that these distances are not

问题 I am trying to make an indoor map of a hospital , when i click on certain buildings it would open their respective indoor maps and when i select a certain area of their respective floor it would show me further details.How can I achieve this? Any suggestions would be appreciated. P.S I have tried using image view but i can't get the image to scroll freely like a real map or a webview (pinch zoom in/zoom out ,rotation etc). 回答1: As you wanted your "floor" to have the behavior of a map you

问题 I'm using indoorAtlas SDK. I already succed to show current location and floorplan using indoorAtlas. But it has some weird result. If i'm inside building that i listed the floorplanid and venue id, it gives the correct current location. But when i'm outside that building and i'm trying to locate current location it gives the result in the floorplan map but it gives some random location. Is there any way to give some notification or action that i'm outside in area that i'm listed floorplanid

问题 I'm developing an application that will use iBeacons for indoor navigation, and I found that the rate the function locationManager:rangingBeaconsDidFailForRegion:withError: is being called is not high enough, so I'm going to add the RSSI data from CoreBluetooth's centralManager:didDiscoverPeripheral:advertisementData:RSSI: . And I found a curious fact: when I listen to the iBeacon with CoreLocation and log the peripheral id: - (void)centralManager:(CBCentralManager *)central

问题 I'm trying to implement a trilateration algorithm into my Android app to determine a user's indoor location. I'm using ultra-wideband beacons to get the distances to fixed points. I was able to adapt the method suggested in Trilateration Method Android Java as follows: public LatLng getLocationByTrilateration( LatLng location1, double distance1, LatLng location2, double distance2, LatLng location3, double distance3){ //DECLARE VARIABLES double[] P1 = new double[2]; double[] P2 = new double[2]

问题 I should be developing an indoor positioning system for some place , so I started by gathering info about how to develop such a system , the question I am up to now is : what controls the accuracy of positioning and how to improve it ? I found different APIs and projects with various accuracies , for example : ericsson indoor positioning API provides an accuracy within 10 meters , while Qubulus API provides an accuracy within 4 meters , and I met some projects like iDOCNET which claims to

问题 So...., I want to use Picasso image loader library with an existing custom imageview class to load,resize,and rotate my image. The problem is I am unsuccessful with it as if I use this code: "Picasso.with(this).load(url).into(custom ImageView)" ,it gives me an error and suggests "cast parameter to target" . After casting the parameter "custom imageview" to target, when I test the application it gives me error saying "custom imageview cannot be cast to target" in the Logcat. After this problem

问题 As a part of my ibeacon based ios application i have to find the current location of the user in my indoor map offline, I am using mapbox SDK for displaying my offline indoor map there is any way to calculate the user location with the help of near by beacons.Thanks in advance. 回答1: Yes! You can use Radius Networks' NavigationKit framework to do offline indoor navigation. There is a reference app that shows you how to use it with an image-based map, but you can modify it to work with mapbox

问题 How to map in real time using indoor beacons on Android? Did tests using the SDK Estimote however, they do not have support for Android in indoor and do not have a method that returns the distance to the beacon. With that, I'm using Alt SDK that returns me the distance. But not her how to solve these doubts: 1) create a map (2D or 3D Google Maps type) with the location map of the inside of a room or shop for example. 2) show the location of the user's route to the beacon. 3) how to deal with
