1. A police speed detection Lidar measurement device for vehicular traffic surveillance in environments having multiple target vehicles, the device comprising:
a video circuitry portion for acquiring video of a field of view having a target vehicle therein, the video including an image of the target vehicle; a steerable laser for performing first and second scans on the field of view, data collected from the first and second scans being stored in first and second target data buffers, wherein reflected laser range-finding signals from the target vehicle are received at the device; a processing circuit portion for identifying target data by performing a best fit analysis comparison on the first and second target data buffers to identify reflected laser range-finding signals belonging to the target vehicle in each of the first and second target data buffers, the target data being data selected from the group consisting of speed measurement of the target vehicle, range measurement of the target vehicle, and heading of the target vehicle; the processing circuit portion executing the best fit analysis comparison utilizing a range measurement, a time measurement, and position in the field of view of the reflected laser range-finding signal the target data being determined based upon the range and time measurements associated with the reflected laser range-finding signals of the first and second target data buffers; the processing circuit portion integrating the target data into the video such that the target data is associated with the image of the target vehicle; and a display in communication with the processing circuit portion, the display for displaying the video including the image of the target vehicle having the target data associated therewith. |
