All-weather two camera shooting laser speed measuring testification apparatus

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...

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 whether the triggering vehicle and the shooting vehicle are the same vehicle, that is, the uniqueness of evidence collection cannot be guaranteed.

But the disadvantage is that the general-purpose analog signal output is converted from analog to digital signal through an external acquisition card. The effective pixels are about 400,000, which cannot solve the resolution problem, and the ideal shooting effect cannot be obtained at night.
