摘要:
A system mounted on a powered industrial vehicle for detecting classifying and tracking in real time at least one obstruction in the scene around the vehicle. The vehicle is capable of moving in multiple directions. The system includes a multiple cameras mounted on the vehicle, wherein the viewing zones viewed respectively by the cameras preferably encompass 360° horizontally around the vehicle. Each of the cameras is operatively attached to an image processor, which processes the image frames acquired respectively by the camera. When a pedestrian is present in the viewing zone viewed by one of the cameras, the image processor attached to the one camera identifies in at least one of the image frames at least a portion of an image of the detected pedestrian.

摘要:
A method in computerized system mounted on a vehicle including a cabin and an engine. The system including a visible (VIS) camera sensitive to visible light, the VIS camera mounted inside the cabin, wherein the VIS camera acquires consecutively in real time multiple image frames including VIS images of an object within a field of view of the VIS camera and in the environment of the vehicle. The system also including a FIR camera mounted on the vehicle in front of the engine, wherein the FIR camera acquires consecutively in real time multiple FIR image frames including FIR images of the object within a field of view of the FIR camera and in the environment of the vehicle. The FIR images and VIS images are processed simultaneously, thereby producing a detected object when the object is present in the environment.

摘要:
A classifier for determining whether an instance belongs to a particular class of instances of a plurality of classes, the classifier comprising: a plurality of first classifiers that operate on an instance to provide an indication as to which class the instance belongs, each of which classifiers is trained on a different subset of training instances from a same set of training instances wherein each training subset comprises a group of training instances that share at least one characteristic trait and different subsets have a different at least one characteristic trait; and a second classifier that operates on the indications provided by the first classifiers to provide an indication as to which class the instance belongs.
摘要:
Classification of an object in the field of view of a camera. A processor is configured to capture multiple image frames from the camera. A candidate image is detected in the image frames. Alignment of the candidate image is determined relative to at least one previously known training image by inputting the candidate image into a trained alignment classifier and outputting one or more alignment variables therefrom associated with the candidate image. The candidate image and the alignment variable(s) are input into a trained object classifier. The object is classified responsive to the alignment variable(s).
摘要:
A vehicle warning system that includes: a first camera mounted on the vehicle at a first longitudinal position along the length of the vehicle, which acquires consecutively in real time a plurality of first camera image frames; a second camera mounted on the vehicle at a second longitudinal position along the length of the vehicle, which acquires second camera image frames; and a processor configured to use information in both first and second camera image frames to determine whether there is a danger of a collision between the vehicle and an object shown in both the first and second camera images. The first and second longitudinal positions may be at different positions along the length of the vehicle.
