Problems solved by technology

[0005] The above-mentioned technical applications can realize the measurement of vehicle size, but the above-mentioned technologies all default that the vehicle is driving straight into the test area. When measuring the vehicle size at the entrance of the smart parking garage, the speed of the vehicle is relatively slow. At this time, due to the road conditions, the vehicle is likely to There is a certain angle with the test area, which leads to deviations in the test results. The test value may be larger than the actual value. The size of the parking space in the smart parking garage is strictly limited, which will cause the vehicles that can be parked to be rejected.

Embodiment Construction

[0037]In order to express the present invention more clearly, the present invention will be further described below through specific embodiments and in conjunction with the accompanying drawings.

[0038] The method of the present invention is suitable for vehicle size measurement at the entrance of a smart parking garage. At this time, the vehicle speed is relatively slow, and due to road conditions, the vehicle is likely to have a certain angle with the test area. The existing test method defaults to driving straight in. If the existing test method is used, the test results will be biased. By adopting the method of the present invention, no matter whether the vehicle drives straight into the test area or enters the test area at a certain angle, accurate testing can be obtained.

[0039] The present invention adopts the following measurement system to test:

[0040] see figure 1 , the measurement system includes a front gantry 1, a rear gantry 6, a left lidar 3, a right lid...

Abstract

The invention provides a method for measuring the outer dimension of a slow-moving vehicle, which belongs to the technical field of measuring equipment. The measurement system used includes front gantry, rear gantry, left lidar, right lidar, rear lidar and processor. The measuring method includes the following steps: judging whether the vehicle enters the area to be measured, correcting calculation of the vehicle entering angle, calculating the vehicle width, calculating the vehicle height and calculating the vehicle length. The present invention corrects the angle of the existing laser radar to test the vehicle size, so that the test result is more accurate, so as to meet the strict screening requirements of the intelligent parking garage for the vehicle size.

Description

【Technical field】 [0001] The invention relates to the technical field of measuring equipment, in particular to a method for measuring the outer dimension of a slow-moving vehicle. 【Background technique】 [0002] At present, various forms of intelligent three-dimensional garages have been widely used, but if the size of the vehicle exceeds the suitable parking size of the intelligent three-dimensional garage during use, the vehicle needs to be stored in the garage, and the owner usually needs to back up and leave the garage. If there is a queue of vehicles at the gate of the garage at this time, it will cause great inconvenience. Even if there is no queue of vehicles, parking, measuring, judging non-compliance, and reversing out of the garage itself are very time-consuming, which greatly affects the parking experience of the car owner. Seriously Under certain circumstances, some three-dimensional garages with small suitable parking sizes are likely to cause the phenomenon of ...
