Passive velocity measuring device

摘要

The presented invention provides the velocity of a moving target from a remote location. A CCD camera receives the image of the target vehicle and records this information on CCD array. The camera then outputs this information in a standard video format such as RS-170, NTSC, or equivalent to the frame grabber circuit card assembly located in the main computer. Custom software along with commercial frame grabber imaging software operates the computer in a Windows or DOS environment. The system will correlate the image of multiple frames stored in the frame grabber circuit card, along with the overlain reference lines and determine the velocity of the target vehicle in miles or kilometers per hour. The image data will be stored in the computer on removable media, along with all pertinent data of the incident including the time/date/location stamp, along with calibration factors and an image of the vehicle operator.
