The system comprises a controller, a driver, an encoder, a gyroscope and an inertial sensor, wherein the controller is respectively connected with an external upper computer, the driver, the encoder, the gyroscope and the inertial sensor, the driver is connected with an external motor, the controller, the driver, the encoder, the gyroscope and the inertial sensor are mounted on an external rotation table, the controller is used for receiving a control instruction sent by the upper computer, controlling the driver to generate a first driving current according to the control instruction, receiving feedback information, used for feeding back the working state of the rotation table, sent by the encoder, the gyroscope and the inertial sensor and controlling the driver to generate a second driving current according to the feedback information, and the driver is used for sending the generated first driving current and the generated second driving current to the motor. According to the scheme, the pointing stability of the optical axis center of the photoelectric sensor during target tracking can be ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photoelectric sensor control, in particular to a control system and method for a vehicle-mounted photoelectric sensor. Background technique [0002] In the detection and recognition of "low, slow and small" targets, in order to facilitate the transfer and use of equipment, the servo turntable equipped with photoelectric sensors is installed on the car body, and the servo turntable controls the photoelectric sensors to realize target search and tracking when the car body is moving. , Compared with the fixed base system, it has strong environmental adaptability and can quickly move to a certain position to complete the task. [0003] However, under the condition of vehicle body movement, due to the shaking caused by the movement of the vehicle body, relative to the fixed base system, the speed and position accuracy of the photoelectric sensor in the inertial coordinate system are relat...

Problems solved by technology

[0003] However, under the condition of vehicle body movement, due to the shaking caused by the movement of the vehicle body, relative to the fixed base system, the speed and position accuracy of the photoelectric sensor in the inertial coordinate system are relatively large, and the optical axis center of the photoelectric sensor is tracking It cannot be guaranteed to point to the center of the target (that is, the pointing stability is poor), which reduces the accuracy of target detection and recognition
