Scanning data rendering method and device, three-dimensional scanning system and electronic device

The invention relates to a scanning data rendering method and device, a three-dimensional scanning system and an electronic device.The scanning data rendering method comprises the steps that whether efficiency optimization is conducted on the rendering process of current scanning data or not is determined according to the real-time rendering frame rate and the hardware resource occupancy rate of the current scanning data; under the condition that it is determined that efficiency optimization is carried out, efficiency optimization is carried out on the rendering process of the current scanning data according to a target efficiency optimization strategy, and a rendering result is obtained; wherein the target efficiency optimization strategy is a preset rendering efficiency optimization strategy matched with the hardware resource occupancy rate. According to the method, rendering efficiency optimization can be realized based on hardware resource occupation conditions, so that the rendering efficiency in a scann
