Kinect v2 depth measurement is greatly affected by the lighting environment, in order to quantitatively analyze the influence of lighting factors on Kinect v2 measurement accuracy, a Kinect v2 depth measurement test system was constructed, orthogonal tests of depth measurement at different distances and different lighting intensities were conducted, the specific areas of noise distribution in depth data were derived, a depth data correction model under the influence of lighting intensity was established. The depth measurement error was compensated. The test results showed that the noise interference in the depth data mainly existed in the edges and four corner parts, and gradually spreaded to the center part with the increase of measurement distance and light intensity, but the effect of light intensity was more significant, and the effective rate of depth data did not exceed 60% when the light intensity exceeded 6500lx. The average relative error of depth data measurement was reduced by 44.55% after the correction of depth measurement data by using the light intensity compensation model. In addition, it was applied in peanut canopy information acquisition to verify the effectiveness of the data correction model.
