Problems solved by technology
[0004] In view of this, the present invention provides a method and device for acquiring a depth image, which is used to solve the current depth detection scheme using a fixed exposure time. When the moving target object is far away, it is easy to cause underexposure and when the target object is close. It is easy to cause overexposure, which in turn leads to the problem that the depth information of the target object cannot be accurately obtained

Embodiment Construction
[0054]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention belong to the protection scope of the present invention.
[0055] First, with the active depth detection scheme based on TOF technology (see figure 1 ) as an example, briefly explain the acquisition process of the depth image. The depth image based on TOF technology is generally calculated from the data of multiple frames of original images such as two frames and four frames, and the method of calculating the depth image by four frames of original ...

The present invention provides a depth image acquisition method and device, belonging to the field of depth detection technology, wherein a depth image acquisition method includes: in the acquisition stage after the target object has been detected from the acquired original image, acquire At least one frame of the original image of the frame depth image; according to the at least one frame of the original image and its exposure time, determine the exposure time of the original image used to generate the next frame of the depth image. The present invention can avoid the problems of overexposure in short distance (the target object is close to the detection module) and underexposure in long distance (the principle detection module of the target object) when detecting the moving target object.
Description
technical field [0001] The present invention relates to the technical field of depth detection, in particular to a depth image acquisition method and device. Background technique [0002] With the development of 3D (3 Dimensions, three-dimensional) technology, more and more technical applications in stereoscopic display, machine vision and satellite remote sensing need to obtain the depth information of the scene. Currently, a depth camera is capable of acquiring depth information of a target object within the camera's field of view. [0003] In the current depth detection scheme, whether it is based on TOF (Time Of Flight) technology, structured light technology or active binocular vision technology, it is a hardware implementation architecture of active infrared light source + image sensor (Image Sensor). In principle, if a fixed exposure time is used to detect moving objects, there will always be problems of underexposure when the target object is far away and overexposu...
