Sorry, but what kind of laser scan is that? It depends. But theoretically, yes, you can use black and white laser scan data and images to create a model. In most cases, the laser scan data are used for mesh creation, the images for textures.
But it is quite hard to scan a person in the same position with laser scan and images, as you are moving during laser scanning, which will create a not so good mesh. And also you need to keep the same position as during image capturing. Also, if it is not a terrestrial laser scanner there could be issues using it in RealityCapture, as RealityCapture supports terrestrial laser scanners where it can use the position and also ordered point cloud.
