El escaneo de superficie incluye técnicas de adquisición de imágenes y su procesamiento. La adquisición se lleva a cabo a través de diferentes dispositivos (e.g., escáneres portables y fijos, cámaras) que capturan imágenes del objetivo, mientras que el procesamiento se realiza a través de software especializado en el cual las imágenes adquiridas son procesadas para fusionarlas en una imagen simple en tres dimensiones. El escaneo en 3D en paleontología de vertebrados incluye una gran variedad de dispositivos que incorporan diferentes técnicas de adquisición de imágenes, los cuales son descriptos y comparados aquí, en términos de sus ventajas y desventajas, considerando el tiempo de escaneo y post-procesamiento, costos y calidad de imagen. La decisión de qué dispositivo elegir dependerá, principalmente, del presupuesto, la transportabilidad y de la naturaleza del material fósil a ser escaneado (e.g., tamaño, peso, accesibilidad). En este sentido, la fotogrametría constituye la técnica de escaneo de superficie que posee la mejor relación costo-beneficio.
