Abstract： This paper aims to reduce the motion blur generated by Time of Flight （ToF）cameras in dynamic scenes，so as toimprove theimagequalityandtheaccuracyofdepthinformation.Acorrection methodbasedongaincalibrationis proposed. Through gaincalibration，thegaincoeficientofeachpixelisaccuratelydetermined，andthe four-bitphaseshift method inthe depthcalculationprincipleisintroducedtooptimizetheexposure time，thusachievingtheefectofimproving theimagequality andtheacuracyof depth measurement.Aseriesof testsontheimprovement effectarecariedoutonthe motionblur test platform.Theresultsshowthatthismethodcansignificantlyimprovethedepth imagequalityoftheToFcamerasindynamic scenes. When the rotation speed of the test device is within the range of 100 to 2 0 0 r / m i n ， the percentage reduction in the number of erroneous pixels caused by motion blur can reach more than 3 5 % ， and can be up to 4 1 . 4 6 % at most. Through experimental verification，the motion blur correction methodforToFcameras basedon gain calibration can efectively improve the image quality and accuracyof depth information，demonstrating itsbroadapplication potential indynamic environments.
