i wondering maximum distance of detection/recognition of image using surf method? has 1 tried. camera: logitech webcam pro 9000
in computer vision distance camera not matter. matters expanse size of object contour. example can place huge object 10km camera's object-glass , still cover whole visual field. cv point of view, same having small object right in front of camera.
known info:
- your camera's max resolution: 1600*1200px
- distance of object: 5m
unknown info:
- size of object - roger rowland's comment totally hit home ;)
- visual complexity of object
- environmental conditions between camera , object
- lighting conditions
you unlikely detect objects further ~2.9 million light-years earth without magnifier lenses, restriction has more kind of physical nature..
