Abstract

The invention provides a depth image imaging system and method. The imaging system comprises light source equipment, filtering equipment, first imaging equipment, second imaging equipment and processing equipment; the light source equipment is positioned at one side of a target scene, and used for at least sending predetermined light; the filtering equipment is positioned at one side of the targetscene, and used for filtering reflected light of the target scene, so that first filtered light and second filtered light are obtained; the first filtered light is obtained by reflecting and filtering the predetermined light through the target scene; the first imaging equipment and the second imaging equipment are positioned at the light exit side of the filtering equipment, and used for respectively imaging the first filtered light and the second filtered light in the predetermined band; and the processing equipment is used for determining the predetermined light according to the second filtered light, and calculating the depth of the target scene according to the first filtered light. The imaging system can measure the depth of the target scene more accurately.

Description

technical field [0001] The present application relates to the imaging field, in particular, to a depth image imaging system and method. Background technique [0002] At present, in addition to the traditional color image, the depth imaging of the subject has appeared in the market, and the depth information is combined with the color image information to be used for the depth of various scenes such as biometrics, AR games, three-dimensional map construction, and robots. Image imaging systems, such as: time of flight technology TOF (Time Of Flight, referred to as TOF), structured light, binocular vision, etc. At present, TOF technology has the advantages of high frame rate, low cost of software and hardware, and long ranging distance, so it is the most widely used method of depth information acquisition. However, because the current TOF technology also has some inherent shortcomings, such as low resolution, missing part of the image, depth value detection needs to be dedupli...
