Intelligent laser tracking system and method for mobile and fixed position traffic monitoring and enforcement applications
An intelligent laser tracking system and method for mobile and fixed position traffic monitoring and enforcement applications. The system disclosed herein can autonomously track multiple target vehicles with a highly accurate laser based speed measurement system or, under manual control via a touch screen, select a particular target vehicle of interest. In a mobile application the police vehicle speed is determined through the OBD II CAN port and updated for accuracy though an onboard GPS subsystem. The system and method of the present invention simultaneously provides both narrow and wide images of a target vehicle for enhanced evidentiary purposes. A novel, low inertia pan/tilt mechanism provides extremely fast and accurate target vehicle tracking and can compensate for geometrical errors and the cosine effect.

Folded path laser rangefinder architecture and technique incorporating a single circuit board for mounting of both laser emitting and detecting elements
A handheld, folded-path, laser rangefinder architecture and technique incorporating a single circuit board for mounting of both the laser emitting and detecting elements is disclosed. The architecture disclosed provides an efficient and low cost design for a laser rangefinder, and by eliminating the conventional provision of separate circuit boards for the laser transmitting and receiving elements, reduces the overall size of the unit and its cost of manufacture by concomitantly eliminating unnecessary interconnecting cables and the like.
Devices capable of capturing still and motion imagery are integrated with an accurate distance and speed measuring apparatus. By measuring the changing distance of the target over that time, a target's speed can be determined. At substantially the same time as the target's speed is determined, imagery of the target is captured in both a still and moving format. Using a queuing mechanism for both distance and imagery data along with time stamps associated with each, a target's image, both in motion and still, can be integrated with its speed. In situations in which a still image is unavailable, a target's speed can be associated with a portion of a continuous stream of motion imagery to a point where a positive identification can be captured with a still image.

Vehicle classification by image processing with laser range finder
An image capture device captures a plurality of sequential images of a vehicle in motion. At substantially the same time a collocated rangefinder determines the distance between the vehicle and the image capture device. Each of the plurality of images may be segmented based on the rangefinder point of reference. The portion of each image representing the vehicle is extracted based on its motion with respect to a stationary background. Knowing the size of the vehicle with respect to the image and the distance that the vehicle is from the image capture device, the image data is converted to real world dimensions. Using these real world dimensions a vehicle classification is determined.
Error introduced by analog to digital conversion of a set of laser pulses can be reduced by shifting the clock reference time associated with the firing of the laser pulse. A timing offset module shifts the timing reference of each laser pulse. Digital codes generated by the ADC from the received signals are realigned and summed eliminating systematic error introduced by clock driven operations of the ADC. A comparison of the total ADC output of detected laser pulses over a select number of clock intervals enables a return signal to be distinguishable over the systematic error.

A high precision, high performance optical system and beam pathway design for laser-based distance measuring, or range-finding, devices includes an etched, or etched and filled, aiming reticle in the image plane which does not require daytime use illumination, and only minimal auxiliary illumination during nighttime operation, thereby conserving available battery power. In a preferred embodiment, a low power consuming back-lit liquid crystal display provides high contrast distance or other operational information to a user superimposed upon a black-appearing field stop thereby further providing operational power savings.

Efficient optical system and beam pathway design for laser-based distance measuring device
An efficient optical system and beam transmission and reception pathway design of particular applicability in the implementation of a cost effective, compact laser-based range-finding instrument. The design is one in which the visual pathway may be made coincident with either the laser transmission or laser reception pathway and may conveniently be implemented in conjunction with a low cost liquid crystal display (LCD) aiming reticle and head up (HUD) information display or in conjunction with a light emitting diode (LED) element. In accordance with the present invention, relatively inexpensive plate mirrors may be used to replace more conventional and costly prism-based implementations.
