Description

Technical Field

[0001] This utility model relates to the field of network camera technology, specifically a black light zoom camera based on the Hisilicon HISI3516DV500. Background Technology

[0002] A black light camera is a photographic device capable of capturing clear images in extremely low light or even no light environments, typically combining infrared light sources or other light enhancement technologies. Its applications and demands primarily stem from the following aspects:

[0003] 1. Security monitoring

[0004] Blacklight cameras are widely used in public safety and traffic monitoring, especially in nighttime or low-light environments such as streets, parking lots, airports, and border surveillance. These scenarios require 24 / 7 video surveillance capabilities, and traditional cameras perform poorly in low light conditions, while blacklight cameras effectively solve this problem.

[0005] 2. Intelligent Transportation Systems

[0006] In intelligent transportation systems, high-definition images are required for vehicle detection, license plate recognition, and road condition monitoring at night. Black light cameras can provide accurate image data in low-light scenarios such as night or tunnels, which helps improve the efficiency of traffic management.

[0007] 3. Military and law enforcement fields

[0008] In military reconnaissance, border surveillance, and police patrols, nighttime or dark environments are often the primary scenarios. Blacklight cameras can help law enforcement or military personnel acquire critical image information under covert conditions without using flash or other visible light sources.

[0009] 4. Industrial Applications

[0010] In some industrial environments, such as mines, submarine pipeline inspections, and underground construction, lighting conditions are poor, yet high-quality image recording and inspection are still required. Blacklight cameras can help acquire clear visual data in such complex environments.

[0011] 5. Home and commercial applications

[0012] In areas such as smart homes and shop security, the demand for nighttime surveillance is also widespread. Blacklight cameras can provide high-quality nighttime video to ensure the safety of homes and shops. Utility Model Content

[0013] In view of the shortcomings of the existing technology, this utility model discloses a black light zoom camera based on the Hisilicon HISI3516DV500, which can make up for the shortcomings of traditional photography technology in low light environment.

[0014] To achieve the above objectives, this utility model is implemented through the following technical solution: a black light zoom camera based on the Hisilicon HISI3516DV500, including a Hisilicon HISI3516DV500 main control chip. The Hisilicon HISI3516DV500 main control chip interface is connected to a video acquisition and processing module, a power management module, a storage module, a video encoding / decoding module, a network transmission module, a clock module, an audio input / output module, and an infrared module. The video acquisition and processing module communicates with the image acquisition module via the Hisilicon HISI3516DV500 main control chip's video access interface. The sensor in the image acquisition module is an IMX464LQR-C. When the light intensity is lower than a preset threshold, the infrared module provides infrared light to supplement illumination and generate a color image.

[0015] Preferably, the power management module consists of a DC-DC chip and a low-noise LDO chip, wherein the DC-DC chip is of model TMI3253 or TMI3255S, and the LDO chip is of model RT9065.

[0016] Preferably, the preset threshold is 0.0001 lux.

[0017] Preferably, the video encoding / decoding module performs H.265 encoding and video compression using HISI3516DV500 to form video packets, which are then transmitted via a wired network.

[0018] Preferably, the network transmission module is composed of a 100 Mbps PHY circuit, and the 100 Mbps PHY chip used is RTL8201F-VB-CG.

[0019] Preferably, the DDR4 in the memory module is an H5TQ4G63EFR-RDC-BGA96 with 4Gbit of memory, used to store currently used data and programs; the FLASH in the memory module is an H26M52103FMR_MISC chip with 16Gbit of storage space, used for fast data retrieval.

[0020] Preferably, the audio input / output module is a built-in module of the HISI35I6DV500 main control chip, wherein the left audio output channel is connected to a Class D power amplifier, the chip model is SN2006 / CS5260, and the right audio input channel is connected to a microphone.

[0021] This utility model discloses a black light zoom camera based on the Hisilicon HISI3516DV500, which has the following beneficial effects: It uses an IMX464LQR-C as the image acquisition module, and simultaneously utilizes an infrared module to actively supplement illumination, projecting infrared light onto the object, which then reflects the infrared light into the lens to form an image. This allows for the acquisition of clear nighttime images while reducing light pollution at night, meeting the needs of some night vision scenarios. Compared to older network cameras, this black light zoom camera based on the Hisilicon HISI3516DV500 has significant advantages, generating high-quality color images in extremely low illumination environments (as low as 0.0001 lux or lower), unlike traditional night vision cameras that can only capture black and white images. This function is very useful in nighttime surveillance or low-light scenarios, such as streets, parking lots, and forests. The black light camera has a built-in intelligent noise reduction function. Especially under low-light conditions where the image signal is weak, noise reduction algorithms (such as 3D noise reduction and spatiotemporal noise reduction) can effectively reduce noise, improve image clarity, and make details more distinct.
