Patent Images
1. A multiple object speed tracking apparatus comprising:
- a camera positioned to capture images of a monitored area;
a set of images of the monitored area that are generated by the camera;
a computer system that can analyze the set of images to detect at least two moving objects that are moving simultaneously within the monitored area;
wherein the computer system provides an on-site speed calibration process that includes a single process for transforming a single frame from the set of images into real world coordinates by considering, in a single step, the perspective of the image in a single frame from the set of images and the scaling of the image in the same single frame from the set of images; and
,an apparatus mount upon which at least one of either the camera or the computer system is positioned, wherein the apparatus mount is one of either a fixed mount or a mobile mount, and wherein a longitudinal axis of the camera may be positioned at any viewing angle in relation to a longitudinal axis of a roadway as long the viewing angle allows images of the at least two moving objects to be included in one of either the set of low resolution images or the set of high resolution images.

18. A multiple object speed tracking apparatus comprising:
-
a camera housing and a camera housing positioning unit; a low resolution camera operatively disposed near the camera housing; a high resolution camera operatively disposed near the camera housing; a computer system including a display wherein the low resolution camera communicates a set of low resolution images to the computer system, wherein the high resolution camera communicates a set of high resolution images to the computer system, and the computer system communicates with the camera housing positioning unit to tilt, pan, and achieve an alignment of at least one of either the low resolution camera or the high resolution camera wherein the alignment allows at least one of either the low resolution camera or the high resolution camera to capture at least one of either the set of low resolution images or the set of high resolution images of a monitored area in which a plurality of moving objects are moving; an apparatus mount upon which at least one of either the low resolution camera, the high resolution camera, or the computer system is positioned, wherein the apparatus mount is one of either a fixed mount or a mobile mount, and wherein a longitudinal axis of the camera may be positioned at any viewing angle in relation to a longitudinal axis of a roadway as long the viewing angle allows images of the at least two moving objects to be included in one of either the set of low resolution images or the set of high resolution images; and
,a software for; analyzing at least one of either the set of low resolution images or the set of high resolution images; utilizing a speed calibration process that includes transforming a single frame from the set of low resolution images into real world coordinates by considering, in a single step, the perspective of the image in a single frame from the set of low resolution images and the scaling of the image in the same single frame from the set of low resolution images; detecting at least one of the plurality of moving objects; determining a speed of travel for the at least one of the plurality of moving objects; determining if the speed of travel exceeds a predetermined speed value wherein the computer system includes a homographic calibration process of determining the calculated rate of speed of the at least two moving objects that includes a linear fit comparison of a set of elements related to a distance traveled by the at least two moving object to a time taken for the at least two moving objects to travel that distance, and wherein the computer system includes a process to ensure better accuracy of the calculated speed of the moving object by not indicating an object has exceeded the predetermined speed value until a determining that a value of a residue of the liner fit does not exceed a preset maximum value of the residue of the linear fit; and
,determining an identification of the at least one of the plurality of objects that has exceeded the predetermined speed value; and preparing a set of incident data related to the at least one of the plurality of objects that has exceeded the predetermined speed value wherein the set of incident data is usable by authorized law enforcement agencies to enforce vehicle speed limits on a roadway by notifying and penalizing the owner of the vehicle that was moving faster than the value of the predetermined speed. - View Dependent Claims (19, 20)
