Imaging device and interference detection method
PendingCN122095272AReduce interference effectsOptical rangefindersElectromagnetic wave reradiationRgb imageOptical axis
The RGB image acquisition unit (30) acquires an RGB image of the object. The ranging image acquisition unit (32) acquires a ranging image of the object along the same optical axis. The RGB image motion detection unit (40) detects movement in the RGB image for each pixel by taking the difference between the current frame and the previous frame. The ranging image motion detection unit (42) detects movement in the ranging image for each pixel by taking the difference between the current frame and the previous frame. The interference determination unit (50) determines whether there is infrared interference during the acquisition of the ranging image for each pixel based on whether there is movement in the RGB image and whether there is movement in the ranging image.
