Abstract: The present invention discloses a time-sequential multi-spectrum image acquiring device structure which uses a single camera module to achieve multi-spectrum image acquiring in a time-sequential architecture, thereby providing a simple, lightweight telemetry system and reducing the development and operation costs thereof. For example, a visible and near infrared (VNIR) imaging system reduces the use of four camera modules (each including an optical lens, filter, sensor, and image signal processing unit) to single camera module, the VNIR imaging system acquires multi-spectrum images having the same image geometric parameters for image calibration and can simplify the calibration process.The present invention is implemented by introducing a multi-spectrum filter wheel capable of rotating in high speed in the camera module and controlling the image acquiring frequency of the sensor and the synchronicity of the wheel rotating speed for multi-spectrum image acquiring. The present invention is suitable for use in multi-spectrum images acquiring of airborne telemetry requiring lightweight system, such as multi-spectrum images acquiring of unmanned aerial vehicle (UAV).
