Problems solved by technology

[0003] The remaining problems and shortcomings of the speeding capture system of the prior art: one is that the clear image of the driver cannot be obtained, especially when the speed of the vehicle is high at night; Trigger, it is difficult to obtain clear images (license plate and model); the third is the front-end control with industrial computer, Windows operating system
Its disadvantage is that the hardware resource utilization rate of the industrial computer is low, and the inherent defects of the Windows system appear after one year of continuous operation, that is, the running speed becomes slower and the control accuracy is lowered, which is fatal to the stability and reliability of the system; four is Communication of images and data is not ideal in terms of simplicity, reliability, real-time, and low cost

Embodiment Construction

[0017] The present invention will be described in detail below with reference to Figs. 3 and 4. As shown in Fig. 3, the present invention includes a controller 21 designed and manufactured without the control of an industrial computer. The pulse generator 23 and the high-speed camera 24; the controller 21 is a high-speed controller HCR composed of embedded software and hardware designed by a large-scale integrated circuit using a Linux software operating system.

[0018] The high-speed controller 21 is connected with at least one color high-definition digital high-speed camera 24 using a megapixel CCD color image sensor, and the high-speed camera 24 is connected to an image memory or monitoring center 25 through a network or an optical fiber.

[0019] The central part of the CCD color image sensor is marked with 300,000 pixels, used for continuous video recording, with a frequency of 25 frames per second, and is connected to a multi-channel hard disk video recorder, or is used for...

Abstract

An over speed catch-shooting system of network high-speed video camera in embedded mode is prepared as connecting radar and pulse generator as well as high-speed shooting head to controller, applying high-speed HCR controller as said controller, connecting said high-speed shooting head with CCD color image transducer to image storage through network and connecting central part of CCD color image transducer to multi-path hard-disc video recorder.

Description

Technical field [0001] The invention relates to a road monitoring equipment-embedded high-definition, digital, network high-speed camera over-speed capture (including bayonet) system, which belongs to the technical field of intelligent transportation (ITS). Background technique [0002] In road monitoring, the existing technology uses ordinary camera technology (25 frames per second), and the system consists of an industrial computer 11, several cameras 12, a light supplement 13, a radar 14 or a coil (or video detection) and a set of corresponding software. , As shown in Figure 1, its working principle is: the radar 14 (or coil or video) detects that the vehicle has come to the detection area and measures its speed. If it is overspeed, it will take a snapshot. Generally, four cameras are used for one-way and two-lane roads. 12. Three of them record the license plate image (ensure the size and number of images of the license plate image) and color, and one records the vehicle type...
