Bus Passenger counting device Door Size Parameter
Door height (counter camera install height) | Door width | Minimum test height | Counter camera lens focal length | note |
1.9M—2.1M | Less than 1.2M | 80cm-90cm | 2.8 | |
2.1M--2.3M | Less than 1.2M | 1.1M | 3.6 | |
2.4M—2.8M | Less than 1.2M | 1.1M—1.2M | 4.0 | |
Greater than 2.8M | Less than 1.2M | 1.2M | 6.0 |
Note：
1.door width less than 1.2M，counter camera height is within this range(1.9M—2.8M)，the bus passenger counter statistical accuracy is over 98%.
2. If counter camera height less than 1.9M, door width is within 1.2M-1.5M range,counter still can work, but accuracy is down.
3, Passenger height no limited, but Minimum height limited.
4.We must know the door height and the door width before use this device. In order to choose different lenses.
5.if door width is bigger than 1.6M , one door requires two cameras to work close together, This case is not common in bus. The accuracy less than 90%.
