Method and device for determining color value of pixel point, equipment and medium

The invention discloses a method and a device for determining a color value of a pixel point, equipment and a medium, and belongs to the technical field of image processing. The method comprises the following steps: acquiring position information of a three-dimensional space point corresponding to a first pixel point in a first image frame and direction information of light corresponding to the three-dimensional space point; inputting the position information and the direction information corresponding to the first pixel point into a trained neural network model to obtain first radiance of the first pixel point; and determining the color value of the first pixel point according to the first radiance. 本申请公开了一种像素点的颜色值的确定方法、装置、设备及介质，属于图像处理技术领域。该方法包括：获取第一图像帧中第一像素点对应的三维空间点的位置信息，以及所述三维空间点对应光线的方向信息；将所述第一像素点对应的位置信息和方向信息输入训练好的神经网络模型，得到所述第一像素点的第一辐亮度；根据所述第一辐亮度确定所述第一像素点的颜色值。
