Problems solved by technology

[0004] 1. Use the radar to collect the vehicle speed, the radar obtains the speed and then captures the video. The main disadvantage is: if the radar works on the roadside, the radar cone angle is 9-20 degrees, and the fixed-angle radar and the horizontal angle of the road surface are 27 degrees -30 degrees, basically the shooting distance is 30-50 meters. If two or more vehicles are driving side by side, it is impossible to judge w

Example Embodiment

[0043] Example: such as figure 1 with 2 As shown, the all-weather dual-camera laser speed measurement and photo proof equipment is composed of a laser speedometer, a color digital camera, and a controller 6 arranged in the chassis 1. The laser speedometer and the color digital camera are located on the same side of the chassis and are connected to each other through wires. The controller is connected, the angle between the laser speedometer and the axis of the color digital camera is 0.03~0.075 degrees in the working range, and the distance between the laser speedometer and the axis of the color digital camera is set to A. The distance between the measured objects is B, find arctgθ=A / B, according to the trigonometric function table to check the value of θ corresponding to arctgθ, you can determine the angle between the digital camera and the laser speedometer and the distance that can be clearly obtained Relationship, see Table 1:

Abstract

The disclosed all-weather dual-camera laser speed measuring and quoting device comprises: a laser speed velometer and a color digital camera both on one side of the case, and a controller connected with former pieces by wire, wherein the included angle between the velometer and camera is between 0deg and 0.075deg, the camera composes by a close-up digital camera and an overall digital camera arranged from upper to lower, and the velometer composes by a laser emitter and a receiver. This invention applies its controller to operate the cameras for fast and accurate images, and fit to all weather work.

Description

technical field [0001] The invention relates to a speed measuring device, in particular to a portable measuring device for measuring the running speed of a vehicle, and the device can also be fixed and installed on the roadside for use. technical background [0002] Due to the rapid growth of the number of vehicles, the casualty accidents caused by the vehicle speed exceeding the safe range are constantly increasing, causing huge casualties and property losses, so the vehicle speed is limited. In order to punish violating drivers, effectively supervise the driving speed of vehicles, and reduce the incidence of traffic accidents, it is necessary to obtain evidence by measuring the speed of driving vehicles. [0003] There are two main types of portable or mobile speed-measuring, photographing and evidence-collecting equipment commonly used: [0004] 1. Use the radar to collect the vehicle speed, the radar obtains the speed and then captures the video. The main disadvantage i...
