What are the advantages and disadvantages of machine vision (video image detection) when compared with other forms of detection?
What will be an ideal response?
The greatest advantage of video image detection is that it is non-intrusive; detectors need not be installed in the roadway (as with inductive loops or magnetometers). Systems such as the Autoscope can detect traffic in many locations within the camera’s field of view. Because of this, a single camera can replace many inductive loop detectors, thereby providing a wide-area detection system. Unlike inductive loops, with video image processing traffic need not be disrupted to install the device and the detection configuration can be changed either manually or by using a software routine. Disadvantages of this method include higher initial costs and that cameras must be dedicated to this purpose and detection zones must be placed precisely for accurate detection.
