    Abstract: A vehicle detection system 200 comprises: a receiver 202 arranged to receive data transmissions from a vehicle 210; a camera 204 arranged to capture an image of the vehicle 210; and a processing subsystem 206 arranged to implement a trained model for detecting and/or classifying vehicles in an image.
    The system 200 is arranged to operate in a first mode wherein: the camera 204 captures an image of a vehicle 210 and the receiver 202 receives a data transmission from the vehicle 210; and the processing subsystem 206 is arranged to use information resulting from the data transmission received and the image to train the model further. The system 200 is also arranged to operate in a second mode wherein: the camera 204 captures an image of a vehicle 210 and the receiver 202 does not receive a data transmission; and the processing subsystem 206 is arranged to use the image and the trained model to detect and/or classify the vehicle 210 in the image.

    Abstract: The disclosed embodiments provide a method performed at a computer system that is in communication with an electric vehicle charging station (EVCS). The EVCS includes a camera for obtaining images in a region proximal to the EVCS. The method includes capturing, using the camera, a plurality of images of electric vehicles, each image in the plurality of images being an image of a respective electric vehicle. The method further includes, for each respective image of the plurality of images of electric vehicles: determining, without user intervention, a characteristic of the respective electric vehicle; and tagging, without user intervention, the respective image with the characteristic of the respective electric vehicle. The method further includes training a first machine learning algorithm to identify the characteristic of other electric vehicles using the tagged plurality of images.

    Abstract: A method of detecting traffic passing a camera overlooking a roadway. The method comprises receiving video frames by a traffic analytics engine from the camera, determining a mask that defines a lane detection region by the traffic analytics engine based on an assumed average length of a vehicle and based on analyzing lane boundary markers in the video frames; determining a background reference frame by the traffic analytics engine by applying the mask to the video frames and by averaging the pixels of the masked video frames; determining that at least some of the masked video frames differ from the background reference frame by more than a detection threshold; and incrementing a traffic count associated with the lane detection region stored in a memory of the computer system based on the masked video frames that differ from the background reference frame by more than the detection threshold.
