Problems solved by technology

[0003] The present invention mainly solves the technical problems in the prior art that it is difficult to clearly photograph and measure the speed of a high-speed vehicle in the occasion where the light is not strong, and the ability to freeze the image is weak.
[0004] At the same time, the present invention also solves the technical problem that the existing night capture technology in intelligent transportation cannot capture one frame expressing the color and vehicle type, and another frame expressing the color and license plate at a sufficiently high shooting frequency.

Embodiment

[0026] Embodiment: Two or more white lines are drawn on the ground at the appropriate position of the expressway, and a high-speed camera and a narrow pulse generator are arranged directly above the direction of travel of the road, and the optical axis of the camera faces the travel of the vehicle Direction, and not far from it is provided with a dedicated industrial computer connected to it, which is provided with an RCC card connected with a narrow pulse generator, and an image acquisition card and a MOXA card connected with a high-speed camera (see attached figure 2 ); the angle between the optical axis of the high-speed camera and the vertical line is about 68 °; the high-power annular high-voltage pulse lamp is arranged next to the high-speed camera, and the power supply is powered by a high-voltage electronic circuit without a transformer. The specially designed RCC card composed of large-scale integrated circuits generates ultrashort pulses from several microseconds to h...

Abstract

This invention relates a method for high-speed grasp shoot of intelligent traffic and its dedicated system device, which comprises following steps: Judging whether it need grasp shoot, controlling CCD high speed cam, fixing the shot picture of automobiles by scanning the background characteristic pattern of the road and computing passing automobile speed by computers; then inputting the picture into picture collecting card, into RAM for digital picture processing; logging in time, place, speed which is stored in hard disk through picture compression; real-time conveying the video picture to remote monitoring center. The light axis of said cam is exposed to the automobile proceeding direction, connected to the special engineering machine set near by and controlled by the machine.

Description

technical field [0001] The invention relates to a high-speed video capture method for intelligent traffic and its dedicated system and equipment. The method and its system can be used in occasions such as expressways, especially mainly used for intelligent management of vehicles on the road, including remote real-time monitoring and management of roads including automatic video monitoring of overspeeding vehicles. Background technique [0002] With the rapid development of economy, the construction, operation and management of expressways are becoming more and more important. However, the existing technology represented by ordinary cameras has the following obvious deficiencies in taking pictures of high-speed moving targets (such as high-speed vehicles): ① The "freezing" ability of the image is not enough: if you want to take a clear picture of a high-speed moving vehicle, its capture The method and system must have sufficient "freezing" ability, otherwise the captured ima...
