Embodiment Construction

[0023] The present invention will be further introduced below in combination with specific embodiments.

[0024] The present invention uses the measurement principle of laser radar to measure. The principle of laser measurement is as follows: the laser source emits a laser beam. When the laser beam encounters an object, part of the energy returns, and the laser receiver receives the returned laser beam. In this way, the laser beam Radar can calculate its distance value to an object. LiDAR scans objects in a two-dimensional area when beams of laser pulses are emitted in two dimensions. Using the characteristics of laser beam reflection to detect the distance between the object surface and the laser within the scanning range, according to the distance from different points on the object to the laser, the position and shape of the object on the scanning surface can be measured and calculated.

Abstract

The invention relates to a device and a method for measuring the sizes of running vehicles. A top laser radar which is used for emitting laser waves toward the direction of coming vehicles to scan the fronts of the bodies of vehicles to be measured is mounted over a vehicle-running lane, and the front end of the advancing direction of vehicles, a side laser radar and a laser rangefinder are respectively mounted within the plane of the entrance of a detection area perpendicular to the lane and at both sides of vehicles to be measured, the side laser radar is positioned above one side of vehicles to be measured, the laser rangefinder is positioned below the other side of vehicles to be measured, and moreover, the distance between the side laser radar and the laser rangefinder is a set distance. The invention can measure the sizes of vehicles as vehicles run, and has no special requirement on the running speed of vehicles, the final detection result is not affected even if vehicles run at non-uniform speeds and even stop for a short time, the detection efficiency is increased, the invention is highly applicable, and thereby the defect of other methods is overcome in terms of applicability; the cost is relatively low; and the precision is greatly increased in comparison with the precision of manual measurement.

Description

technical field [0001] The invention belongs to the field of optoelectronics and its laser technology, in particular to a method for volume measurement or recognition of irregularly moving objects, and in particular to a method for volume testing of running vehicles. Background technique [0002] In some occasions, it is necessary to perform measurement work such as volume testing on moving objects such as vehicles. The conventional method of vehicle volume measurement is to stop the vehicle to be measured and perform contour measurement manually or by instruments. The disadvantage is that the efficiency is low, and the accuracy of volume measurement will be affected when the vehicle is not loaded smoothly. Contents of the invention [0003] The object of the present invention is to provide a device for testing the volume of a running vehicle, so as to solve the problems of low efficiency and low accuracy of existing measuring methods, and at the same time provide a method...
