主動式影像擷取之光學系統及光學方法

Abstract

一種主動式影像擷取之光學系統及光學方法，供擷取一物體的一光場資訊以建立一物體模型，該光學系統包含一處理單元、一光發射單元與一擷取單元。該處理單元依序地產生複數個調變訊號與複數個同步訊號。該光發射單元藉由該等調變訊號調變一第一光線並將該第一光線發射至該物體，以在該物體反射具有該物體之光場資訊一第二光線。該擷取單元藉由該等同步訊號，在每一調變訊號調變該第一光線的過程中，同步地擷取該第二光線以產生一影像。該處理單元執行一第一演算法計算複數個該影像與該等調變訊號以建立該物體模型。 The invention is related to an active image acquisition system and method. The active image acquisition system retrieves light information of an object for creating an object model. The active image acquisition system comprises a processing unit, a light emitting unit and a capturing unit. The processing unit generates a plurality of modulating signals and a plurality of synchronous signals seriatim. The light emitting unit modulates a first light beam by the modulating signals, and the first light beam is emitted to the object. The object reflects a second light beam after the first light beam incident into the object with the light information. The capturing unit generates an image after capturing the second light beam in each modulating signals modulating the first light beam. The processing unit performs a first algorithm for calculating a plurality of the images and the modulating signals, and creating the object model.
