Embodiment Construction

[0057] figure 1 It is a flow chart of Embodiment 1 of the state detection method of the parking space of the present invention, and the state detection method of the parking space of this embodiment includes the following steps:

[0058] S11. The laser vehicle inspection equipment performs laser scanning on the parking area, and collects detection data, and the detection data includes a plurality of sampling points and distance data corresponding to each sampling point;

[0059] In this step, combine figure 2, the parking area includes four parking spaces set on the side of the road, and the laser vehicle inspection equipment 10 set on the other side of the road includes a single-point laser, a rotating pan-tilt, and a universal joint. The universal joint is used to adjust the laser emission angle of the laser, and the rotating pan / tilt is used to control the laser scanning. By rotating the pan / tilt and the universal joint, the scanning range can cover the parking space that...

Abstract

The invention relates to a parking spot state detection method and a laser vehicle inspection device. The parking spot state detection method comprises the following steps: a laser vehicle inspection device scans a parking area with laser, and collects detection data, wherein the detection data includes multiple sampling points and distance data corresponding to each sampling point; and the state of each parking spot is acquired according to the detection data and pre-stored background data, wherein the background data includes the sampling interval corresponding to each parking spot during parking spot calibration, multiple sampling points and distance data corresponding to each sampling point. Through the technical scheme of the invention, the detection precision is high, and the environmental adaptability is good. There is no need for pavement excavation in device installation, commissioning, maintenance and other work, the damage to the pavement and the impact on normal traffic behavior are reduced, and the labor cost is reduced. The average cost of state detection of parking spots can be reduced, and the number of devices installed can be reduced.

Description

technical field [0001] The invention relates to the field of parking space detection, in particular to a parking space state detection method and laser vehicle inspection equipment. Background technique [0002] At present, the main equipment used for parking lot status detection includes geomagnetic vehicle inspection equipment, ultrasonic vehicle inspection equipment, video vehicle inspection equipment, etc. The main problems of geomagnetic vehicle inspection equipment are that the road surface needs to be damaged during installation and maintenance, the short service life of the equipment leads to high maintenance frequency, the probability of misidentification is high, and one geomagnetic vehicle inspection device can only detect one berth, etc. Ultrasonic vehicle inspection equipment is only suitable for indoor parking lots, the signal weakens quickly and can only detect one berth, and the false recognition rate is high. Video vehicle inspection equipment does not work...
