  • Patent number: 10635929
    Abstract: The present invention belongs to the field of machine vision. A saliency-based method for extracting a road target from a night vision infrared image is disclosed. The method combines saliencies of the time domain and the frequency domain, global contrast and local contrast, and low level features and high level features, and energy radiation is also considered to be a saliency factor; thus, the object of processing is an infrared image and not the usual natural image. The extraction of a salient region is performed on the raw natural image on the basis of energy radiation, and the obtained extraction result if the salient region is more accurate and thorough, and the contour of a target in the salient region is clearer.

  • Publication number: 20190263399
    Abstract: Provided is an intelligent vehicle safety driving envelope reconstruction method on the basis of integrated spatial and dynamic characteristics. Starting from simulating an actual driver's estimation of potential collision risks in the forward driving area, a prediction result of a front vehicle driving behavior is introduced to an environment perception link of the intelligent vehicle; on the basis of the prediction result of the front vehicle driving behavior, a safety driving envelope of the intelligent vehicle is reconstructed by integrating spatial and dynamic characteristics (a safety environment envelope reconstruction and a stable control envelope reconstruction), so as to improve the safety and stability of intelligent vehicle.

  • Publication number: 20190156668
    Abstract: A driving service active sensing system and method in an Internet of Vehicles environment in the field of road traffic safety. A sensor device and an intelligent vehicle-mounted terminal arranged on a vehicle and connected to each other. The intelligent vehicle-mounted terminal communicates with roadside equipment in 4G and DSRC modes, and communicates with a driving service information processing center in 4G mode. The roadside equipment communicates with the driving service information processing center in 4G mode. The roadside equipment is provided on both sides of a road. The sensor device outputs obtained vehicle traveling information to the intelligent vehicle-mounted terminal, which processes and integrates the received vehicle traveling information and then transfers integrated information to the roadside equipment and the driving service information processing center.

  • Patent number: 9088102
    Abstract: The present invention relates to an anti-loose socket and a pull-out locking mechanism thereof, wherein inside the anti-loose socket, there are a pull-out locking mechanism composed of a bevelled sleeve (15) and two cylinders (16) arranged in a symmetrical manner at two sides within the bevelled sleeve; an inside longitudinal section of the bevelled sleeve has a cone angle in an umbrella shape, the middle portion of the bevelled sleeve allows a plug pin (61) to pass through; the cylinder is mounted on a floating block (14) movable up and down, and can move up and down along the inside conical surface of the bevelled sleeve by the floating block. When the plug (6) is pulled out upwards, the cylinder moves upwards, however due to the limiting action of the bevel surface, the cylinders stick to the two bevel surfaces more and more tightly.
