Auxiliary Focus

With the rapid development of fields such as intelligent recognition, attendance tracking, security, surveillance, and epidemic prevention, the need for precise target recognition has become increasingly urgent for projector manufacturers, temperature measurement device manufacturers, and camera manufacturers. Benewake has launched a LiDAR-assisted focusing application solution to help camera manufacturers, projector manufacturers, and temperature measurement device manufacturers achieve precise distance measurement and focusing. Additionally, it can detect whether there are individuals approaching within the attendance machine area, measure the distance between the attendance machine and the individuals, and assist in focusing.

The distance sensor emits infrared light or ultrasonic waves to the target being measured. The returned measurement values are provided to the camera, projector, or temperature gun systems to achieve assisted focusing functionality.

Some infrared thermal imaging cameras have lenses with shallow depth of field and limited focusing accuracy, making it difficult to measure the human iris. Therefore, by installing Benewake LiDAR on the device, the distance between the device and the human iris can be accurately measured to assist in focusing. This integrated device for surveillance is flexible in deployment and can accurately identify individuals even when wearing masks. With the precise ranging function of Benewake LiDAR, the product can quickly focus on the human iris for temperature measurement within 1 second.

Installing a thermal imaging camera automatic temperature measurement and attendance integrated machine in office buildings, parks, and other work areas can quickly achieve functions such as "iris face recognition + long-distance temperature measurement + attendance recording," thereby eliminating contact-based infections.
