Wireless Camera Sensor With High Sensitivity Vehicle Detection For Sale
Wireless Camera Sensor
Wireless camera sensor. The wireless camera sensor is mainly composed of an external field camera, a data transmission device, and a video processor. The outfield camera captures the traffic image of a section of the highway and transmits it to the video processor via the data transmission device. The image processing hardware of the video processor displays the image on a computer monitor and then uses the interactive control software to set a virtual coil and a thick line on the traffic image with the mouse as a speed detector and a count detector. The size and number of virtual coils and thick lines can be adjusted at any time according to the situation of the traffic image. When the vehicle passes through the virtual coil and the thick line, a detection signal is generated. After analysis and processing by the video processing software, parameters such as vehicle speed and traffic volume can be obtained.
For wireless camera sensor, the biggest problem is the image source. For a wireless camera detection that can achieve the wireless camera detection requirements of an image source, there may be a serious drop in the index for another image source. The more obvious examples are day and night, with shadows and no shadows. Therefore, the image source should be a collection of typical images. The test of an indicator should be performed on all objects of a typical image collection. The ability of the tested product to adapt to engineering practice depends on the scientific and typicality of the image source set. And representative. For a typical image source set, the key parameters such as the lowest output signal-to-noise ratio, resolution, and dynamic range should be specified. Traffic flow parameter detection is a basic function of a video vehicle detector. Its essence is to detect the presence of a vehicle in a particular detection area and thereby measure other parameters of the traffic flow. These parameters may be instantaneous or instantaneous. The value calculates the statistical value. The time characteristic refers to the response time of the wireless camera detector, and its exact meaning of refers to the time interval from the moment the vehicle reaches the detection area set by the detector to the moment when the detector confirms that the vehicle exists. Reflects the time delay of the wireless camera sensor. For wired and wireless camera detector. The different customer has a different choice.
The accuracy of the speed measurement and the accuracy of the traffic volume are basically maintained at a high level. At present, the speed measurement accuracy of the commonly used video vehicle detectors in China is above 95%, and the traffic volume counting accuracy is generally around 98%. After many on-site inspections, it is found that after using a high-sensitivity camera with strong light suppression, the same detection accuracy as in the day can be achieved without road illumination at night.
