The technical requirements for the camera of the in-and-out stock scanning device

High resolution: The barcode scanner for warehouse entry and exit needs to process various types of information. A high-resolution camera can ensure that barcodes, QR codes, and cargo details are clearly distinguishable. It is generally recommended to have at least 5 pixels, corresponding to a resolution of about 2592×1944dpi, so that it can clearly present small barcode patterns and avoid information reading due to insufficient pixels. In warehouses dealing with precision electronic components, the QR codes on the components are very small, and a high-resolution camera can accurately identify themAccurate color reproduction: For some scenarios where cargo information or batches are distinguished by color identification, accurate color reproduction is essential. The camera needs to have excellent color calibration to ensure that the colors of the goods shot are consistent with the actual colors. The color bit depth is usually required to be 24 bits or more, thus reliable basis for subsequent recognition and classification based on color information.

Fast autofocus: The speed of goods during warehouse entry and exit is not consistent, and camera needs to quickly autofocus to capture clear images. The focusing speed should be within 0.5 seconds, which can quickly lock onto goods at different distances and ensure barcodes and QR codes can be clearly read at any position. For example, when the conveyor belt transports goods quickly, the camera can quickly respond and complete focusing.

depth of field: A larger depth of field range can ensure that goods of different thicknesses or stacked goods can be clearly imaged. The ideal depth of field should a distance from a few tens of centimeters to several meters, so that whether it is a single good or a multi-layer stacked good, there is no need to adjust the camera position to clearly shoot, which improves the scanning efficiency.

Low distortion lens: Lens distortion will cause the barcode or cargo shape in the to be distorted, affecting the accuracy of recognition. The camera of the barcode scanner for warehouse entry and exit should use a low distortion lens, and the distortion rate is controlled within 1%, to ensure that the barcodes and QR codes in the image maintain their original shape and are convenient for accurate recognition.

Good light adaptability: warehouse environment has complex lighting conditions, and the camera needs to work normally under different lighting conditions. With the function of automatically adjusting exposure, it can quickly adapt to light, weak light, backlight and other environments, ensuring that the image is clear and bright, without over-bright or over-dark areas. At the same time, low light environments, the camera's sensitivity should be high enough to reduce the generation of noise and ensure image quality.

High-speed data processing: camera needs to quickly process the acquired image data, and cooperate with the recognition algorithm of the barcode scanner to achieve fast and accurate recognition of barcodes and QR codes. built-in image processor should have powerful computing capabilities, and be able to complete image preprocessing, feature extraction, and recognition operations in a short period of time, ensuring that scanning response time is within 1 second.

Stable data transmission: It is essential to transmit data stably with other components of the barcode scanner. High-speed USB or Ethernet interface is usually used to ensure that the data transmission rate is not lower than USB3.0 standard (5Gbps), to avoid data transmission delay or, and to ensure that image data is transmitted to the main control system of the barcode scanner for subsequent processing in a timely and accurate manner.

Dust and water resistance: The warehouse environment may contain dust and moisture, so the camera should have a certain level of and water resistance, at least reaching the IP54 standard, to prevent dust from entering the interior and affecting the imaging quality, and to ensure normal operation in the of slight splashing, ensuring long-term stable operation in harsh environments.

Wide temperature operating range: To adapt to temperature changes in different seasons and within the warehouse, the temperature range is generally required to be between -20℃ and 50℃, ensuring that the camera can operate normally in both cold winter and hot summer, performance degradation or failure due to excessive high or low temperatures.

Hardware compatibility: Good compatibility with the mainboard, processor, and other hardware devices of the-and-out stock scanning device, ensuring stable coordinated operation of all components, without hardware conflicts or compatibility issues, and ensuring the stable performance of the scanning device as a wholeSoftware compatibility: Support for the operating system and recognition software used by the scanning device, and the ability to smoothly connect to the Warehouse Management System (WMS). At same time, it is convenient to upgrade the software and expand the functions in the later period, to adapt to the changing needs of goods recognition and management.
