The security millimeter wave radar module is perfectly combined with the vision system to build security. The vision system will make false positives in harsh environments, and false positives are a big challenge for vision. In the actual environment, the light changes, the complexity of target movement, shielding, the color of target and background is similar, the background is messy, and the environment is bad, leading to a large number of false positives and false negatives in video analysis. Clear images can be denoised and sharpened by computer. By adjusting the image size, with the help of the high resolution of the display, you can see clear and high-quality images, store them for a long time, and call them in real time.
The advantages of the security millimeter wave radar module are extremely applicable in harsh environments, while the disadvantages are that no clear image can be seen. Because the wavelength of the millimeter wave is between the centimeter wave and the light wave, the millimeter wave has the advantages of microwave guidance and photoelectric guidance. The security millimeter wave radar module can accurately detect the moving direction, distance, speed and angle of moving targets. Compared with infrared, laser, video and other optics, millimeter wave has the ability to penetrate fog, smoke and dust, and has all-weather characteristics.
The security millimeter wave radar module+vision system can give full play to their respective advantages, and integration is the trend of the times. The radar vision integrates intelligent warning products. The radar judges the accurate position of the target by target distance, angle and speed, integrates video analysis technology for target review, and uses artificial intelligence for target inspection (AI) algorithm to determine whether it is the target for alarm.
The security millimeter wave radar module is integrated with the signal level of the vision system, perfectly integrating the active detection of radar technology, data judgment and visibility of high sensitivity and video intelligent analysis, and greatly improving the detection and recognition rate of the system. Integrated comprehensive design, power supply and unified installation can effectively save material cost and installation cost.
The security millimeter wave radar module is fully integrated with vision, and vision provides clear images. The radar accurately detects the moving direction, distance, speed, angle, millimeter wave radar and vision integrated system make full use of the respective advantages of sensors, give full play to their respective advantages, integrate artificial intelligence technology, and make full use of the range, target coordinates, and range based moving targets given by radar location7 × 24-hour all-weather real-time protection, adapt to rain, snow, fog, haze, sand and dust and other bad weather, to prevent false positives to a large extent, and eliminate false positives.
Function of security millimeter wave radar module in the integrated lightning vision machine:
1. Defense area drawing and alarm track setting: freely draw alarm area, filter area and early warning area;
2. Alarm record: when an intrusion target is found, the alarm system will continue to send out pulse prompts and record alarm information;
3. Regional overlay: video coverage area and radar coverage area are uniformly stacked and coordinated;
4. Tracking target focus: provide real-time vision through radar target tracking track. Vision can track radar coordinates and adjust the optimal distance to achieve clearer and higher quality records.
How to select the appropriate security millimeter wave radar module?
1. Radar algorithm capability: low false positives and few false positives. At present, the domestic radar technology has gradually matured, and the radar has entered a period of rapid development. However, the algorithm capabilities of various manufacturers are still uneven, specifically, the shaking of trees, trees and shrubs. Our radar has achieved false alarm less than once a day on average through AI technology.
2. Look at the radar function: The important choice is to choose the radar according to your application needs, such as personnel detection range, vehicle detection range, radar coverage angle, etc. At the same time, the horizontal range of the camera shall be combined to overlap with the angle of the camera, and the area shall be covered with large angle, with the horizontal angle of 60 °~120 °。
