Samsung FREE Camera FOV check (AR) version1.0 Download
'Camera FOV check (AR)' is an augmented reality application, which can help people to find proper surveillance camera parameters (position, rotation, field of view) before installing it in reality. A trackable MARKER can be placed somewhere near the future surveillance camera position but in place accessible without effort.
Application is a tool, which should be used to get some advices before serious security system parameters calculation or during presentation for customers.
what is needed ? 1. Android smartphone or tablet with BACKSIDE CAMERA - it will also work with front-side cams, but it will be far from convenience. 2. printed trackable MARKER - please download it from << http://goo.gl/xuJQG >> and print it (please follow printing tips below).
(!) printing tips - to have correct scale of position units (cm) MARKER has to be A4 or A3 full page size - do not set any margins and borders or minimize them. - A3 size of MARKER is recommended (A4 will work fine for distances less then 3 meters only) - use white, matte paper (any reflections can cause tracking errors)
How does it work?
When application is installed and running, MARKER is on its place (e.g. attached to the wall), not occluded and well illuminated, just point your device camera on it. Virtual camera will appear in the middle of the MARKER.
On the left side you can choose operation you want to perform with your virtual camera (move, rotate, vertical field of view angle change). To increase/decrease horizontal or vertical parameters just swipe your finger along screen X or Y axis.
(!) In this version only vertical field of view angle can be adjusted, horizontal FOV is calculated from vertical FOV and virtual camera screen aspect ratio, which is locked on 4/3.
To see what is in scope of virtual camera vision you can watch blue lines displayed along virtual camera field of view edges and change your observation position.
In addition you can use virtual camera view (left-bottom corner) where, in an artificial cubic space, an orange box is floating around in the air. This box is your device avatar seen from your virtual camera and the blue frame is this virtual camera field of view. It is easy to catch, when your device is crossing the blue lines, which means, you felt out of your virtual camera field of view.
Phew.. that's quite easy and obvious after 1 minute of testing.
