Abstract
An embodiment of the present invention provides an image device for generating velocity maps. The image device includes an image capturing group, a depth map generator, an optical flow generator, and a velocity map generator. The image capturing group includes at least one image capturer, each image capturer of the image capturing group captures a first image at a first time and a second image at a second time. The depth map generator generates a first depth map according to the first image and a second depth map according to the second image. The optical flow generator generates first optical flow according to the first image and the second image. The velocity map generator generates a first velocity map according to the first depth map, the second depth map and the first optical flow, wherein the first velocity map corresponds to the first image.
