[0002] Binocular drones are based on dual cameras and imitate human vision. They have obvious advantages over monocular drones in target perception, target recognition and detection, and are now more and more widely used. Traditional binocular drones generally use MIPI to transmit images. The design and connection relationship of MIPI-based video transmission circuits are relatively complex. In order to adapt to various cameras, the design and implementation are very difficult and generally costly.

[0003] With the deepening of binocular drone applications, the demand for TOF (Time of Flight) sensors is increasing. TOF sensors are based on light reflection ranging, and combined with binocular camera image acquisition, they can achieve better target detection effects. However, at present, binocular drones lack a unified TOF interface, and the integrated circuit structure makes it very inconvenient when the TOF sensor fails or is replaced, which increases the difficulty and cost of maintenance. In addition, the application scenarios of a single type of TOF sensor are single, which is not conducive to expanded applications.

[0004] On the other hand, existing binocular drones generally do not have LED fill light circuits. When the ambient light is poor, they cannot provide fill light for the camera to achieve better shooting effects. Utility Model Content
