An imaging environment that greatly affects image recognition accuracy is recognized for applications in onboard systems of various sorts including imaging devices. An imaging device for imaging areas around the vehicle is mounted on a vehicle. Before executing image recognition processing, information is acquired on objects and texture, such as traffic signs and pedestrian crossings, present within a field of view of the imaging device. An object or texture present within the field of view is then recognized by an image recognition section. Degrees of distortion and defocus of a shape or texture of the object recognized are calculated based on the shape or texture of the object recognized and information previously acquired on the objects or texture. Imaging environment, such as water droplets or dirt on a lens, and whether fog occurs or not, is then recognized based on the degrees of distortion and defocus calculated from the shape or texture of the object recognized.

The invention discloses a real-time identification method of the live panoramic traffic signs. Aiming at the real-timely acquired large-resolution panoramic traffic images, a proposed data processingmethod is used to extract a training set, and a proposed TSNet network is trained and fine-tuned. In the detection stage, after the image is scaled based on an image pyramid, the sliding window processing method and a DS-NMS algorithm are used to ensure the real-time target identification and improve the accuracy, so that the traffic signs can be identified quickly and accurately in the panoramicstate.

Allocation of a wireless communications system channel resource is managed by utilizing traffic segment allocation. This is realized by partitioning the channel resource into an assignment channel and a traffic channel in a fixed manner. The assignment channel includes assignment segments and the traffic channel includes traffic segments. The traffic segment is the basic traffic channel resource unit used to transport traffic data and has a prescribed finite time interval and bandwidth. Each traffic segment is associated with a so-called assignment segment in a prescribed manner. One or more traffic segments may be associated with a particular assignment segment. A base station broadcasts via an assignment segment which wireless terminal is to use a particular traffic segment. This is realized by transmitting a simply identifier for the particular wireless terminal assigned to the particular traffic segment in the assignment segment. Then, each active wireless terminal monitors all of the received assignment segments to detect any traffic channel assignments. Once a wireless terminal detects its identifier in an assignment segment, it proceeds to receive/transmit the traffic data in the traffic segment associated with the assignment segment including the detected identifier.

A sign provided by the present invention comprises a base and a strut installed on the base, the strut is fixed on the base by a hemisphere arranged at its bottom and embedded in the base; the top side wall of the hemisphere passes through Four shear pins evenly distributed around the circumference are fixed to the base; the upper and lower sections of the strut are connected by joint bearings. The connection between the strut and the base is realized through the hemisphere. When receiving an external force, the hemisphere will break free from the shackles of the shear pins under the action of the external force and actively displace, thereby buffering part of the external force and effectively reducing the impact of the external force. The damage of the struts is easier to recover or replace after the external force is removed, and the normal traffic instructions can be restored in time.

This invention is a glass fibre-reinforced-plastic traffic tag and its produced method. On the one side of this glass fibre-reinforced-plastic tag there is a installing slip, on the other side of this tag there are traffic signs and words. The steps of produced method of this tag: 1) Selecting proper pattern of the glass fiber-reinforced-plastic tablet according to the demand of the road traffic safety; 2) To fix the installing slip onto the tag; 3) Produce the traffic signs and words on this tag.

The invention discloses a method for widening an expressway at an overpass. By constructing the wall-type underground continuous structure at the side of the original road, the method can maintain thestability of the original road after excavation, at the same time, it provides the possibility for reducing the height of widening pavement to meet the net height, and also increases the possibilityfor satisfying the demand of lateral widening, that is, it provides the possibility for direct widening. At the same time, through the reasonable marking, set up the same lane separation belt, supplemented by the necessary traffic signs, can guide vehicles to drive safely. A method accord to that invention has the advantages that: A wall-type underground continuous structure and a co-directional lane partition are arranged, In order to solve the problem of clearance caused by direct widening under the flyover, a beneficial method is provided for widening the expressway at the flyover. This method can avoid the problems such as more space, large project scale and large environmental impact caused by demolishing the flyover and rebuilding or separating a new road.
