Description

Technical Field

[0001] The utility model relates to the technical field of smart parking lots, and in particular to an entry and exit gate of a parking system. Background Art

[0002] In parking management systems, traditional gates usually use a single recognition technology, such as license plate recognition cameras, to detect and identify vehicles entering and leaving. However, this single recognition method has many limitations. First, for license plate recognition, if the license plate is blocked, defaced, or there are other interference factors, the recognition rate will be greatly reduced, and even lead to misjudgment. Second, when a vehicle attempts to enter or leave the parking lot in an abnormal manner, such as using a fake license plate or rushing through the gate quickly, the traditional system often has difficulty responding in time, thus bringing safety risks to parking management.

[0003] The above patent documents and prior art have the following technical problems:

[0004] 1. Traditional systems often rely on simple sensors or manual confirmation to determine whether a vehicle has successfully passed through the gate. They lack reliable visual verification methods, which can easily lead to misjudgment or missed judgments.

[0005] 2. The cameras of traditional gate systems usually can only cover a limited field of view, have visual blind spots, and cannot fully monitor vehicles and their surroundings, affecting the system's recognition and judgment capabilities. Utility Model Content

[0006] The utility model aims to solve the shortcomings of low intelligence of gate detection and insufficient coverage of detection range in the prior art, and proposes an entry and exit gate of a parking system.

[0010] Preferably, the adjacent side connections on the outside of the gate body are rounded, and the bottom surface of the gate body is bolted to the external ground.

[0011] Preferably, the scanning field of view angles of the first binocular vision sensor and the second binocular vision sensor are both 150 degrees.
