The development trends of smart turnstiles cover four core directions: lightweight structure, intelligent monitoring capability, contactless payment and big data analytics. To tackle the drawbacks of traditional turnstiles, LEGATE draws on its professional strengths and years of experience to conduct in-depth research on high-efficiency intelligent passage technology. Among various 3D computer vision recognition algorithms, the depth-image binocular stereo vision recognition technology originally used in navigation scenarios perfectly satisfies the application demands of high-efficiency intelligent passage systems.

We comprehensively upgrade the measurement logic for passenger passage with binocular depth vision detection technology:

• The VSM binocular vision sensor achieves precision 3,500 times higher than the second-generation passage logic based on 16 to 22 pairs of through-beam sensors.

•  The overhead binocular vision sensor can unobstructedly detect all objects within its field of view, calculate their 3D dimensions and contour shapes, and track the motion of up to 8 valid targets.

•  There is no mandatory physical length limit for the turnstile lane; virtual lanes can be fully realized for contactless payment scenarios.

Features of Binocular Vision Ticket Checking Gate

•  The minimum lane length of the equipment can be 1200 mm or even shorter, which effectively reduces the floor space occupied in station halls.

•  Customizable ticket checking policies for different passenger groups (e.g., extended release delay for wheelchair passengers).

•  Safety passage protection for vulnerable passengers such as pregnant women and travelers carrying oversized luggage.

• High-precision detection of fraudulent behaviors including reverse intrusion, tailgating, overlapping passage and side-by-side crossing, with video evidence recording function.

• Supports monitoring of card-swiping passengers and interception of non-card-swiping passengers (this function is subject to operational rules).

• Built-in child height detection; children can pass either in front of or behind adults without restrictions, with an ultra-low passenger omission rate.

• Self-learning and iterative evolution capability.
