Tsingtao license plate recognition factory, system recommendations
It is recommended to install a speed bump before triggering the recognition sense to ensure that the vehicle slows down before reaching the trigger sense. It is recommended to install at least one speed bump, and it is recommended to install about 80 cm before the trigger sense. It is recommended that the installation location of the equipment should be avoided in environments where the brightness of the internal and external light is very different, such as the underground garage entrance, the outside is the outdoor environment, and the inside is the indoor environment. It is recommended that the equipment be installed in a flat position. At the same time, the camera installation needs to have a tilt degree to avoid the high light and direct sunlight of the car. If the lighting conditions on the site are better, auxiliary light sources are usually not installed to save costs Channel planning 1, the width of the lane should be limited to 3 meters, and use the plastic warning column(isolation column) to plan the car route, out The access channel should be separated from the passenger and vehicle passages. As far as possible, security or pedestrians stay in front of the camera to ensure that there are no objects blocked by pedestrians, electric cars, umbrellas, etc., to ensure that the recognition camera has a good identification environment. Equipment installation 2 The distance between the camera stand and the edge of the cement island must be controlled within 0.2 meters(as shown in Figure 4). The closer the distance, the better. The angle between the optical axis direction and the road direction of the identification camera should be less than 25 degrees(as shown in Figure 5). matters needing attention 3, the license plate recognition camera grabs the ground sensation trigger place, the ground is preferably the horizontal plane, the license plate recognition camera triggers the ground sensation place The party should reserve a straight road of 2 meters(as shown in Figures 1 and 2) and install a isolation column to ensure that the vehicle remains straight after turning. (Gangting terminal entrance) Figure 1 Qingdao plate recognition factory (Single Channel Entrance) Figure 2 Note: If the site is a ramp, it is necessary to adjust the distance triggered by the camera(if the vertical bar can be telescopic or adjust the height of the vertical bar) to properly reduce the height of the vertical pole when going up the slope, and the trigger sense can be set to 4.5 M when going downhill., To make sure the plates the cameras recognize are horizontal, Figure 3 4, the width of the lane should be limited to 3 meters, and the use of plastic warning columns(isolation columns) to plan the car route, out The access channel should be separated from the passenger and vehicle passages. As far as possible, security or pedestrians stay in front of the camera to ensure that there are no objects blocked by pedestrians, electric cars, umbrellas, etc., to ensure that the recognition camera has a good identification environment. The distance between the camera riser and the edge of the cement island must be controlled within 0.2 meters(see Figure 4). The closer the distance, the better. The angle between the optical axis direction and the road direction of the identification camera should be less than 25 degrees(as shown in Figure 5). * Figure 3 4, the width of the lane should be limited to 3 meters, and the use of plastic warning columns(isolation columns) to plan the car route, out The access channel should be separated from the passenger and vehicle passages. As far as possible, security or pedestrians stay in front of the camera to ensure that there are no objects blocked by pedestrians, electric cars, umbrellas, etc., to ensure that the recognition camera has a good identification environment. The distance between the camera riser and the edge of the cement island must be controlled within 0.2 meters(see Figure 4). The closer the distance, the better. The angle between the optical axis direction and the road direction of the identification camera should be less than 25 degrees(as shown in Figure 5).
