Problems solved by technology

[0003] Due to the difference in the scene where the target is located, for example, there is a large scene difference between an indoor target and an outdoor target, and most of the current 3D sensors are not suitable for multi-scene applications. Due to the scene difference, the obtained depth image There is an error

Embodiment Construction

[0019] see figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for obtaining a target depth image in the present invention, including:

[0020] S101: adopt at least two working modes, collect image information of the target at the same time, process the collected image information respectively, and obtain at least two depth images;

[0021] S102: Compare the detail information of at least two depth images, and output the depth image with less detail by default as the target depth image:

[0022] Specifically, compare the brightness of the same region of the target on at least two corresponding regions of the depth image, and output a depth image with a large brightness contrast of adjacent regions and less periodically repeated texture as the target depth image.

[0023] Step S101 will be further described in detail below.

[0024] In this embodiment, two working modes are adopted to collect images of the target at the same time, namely the first wo...

Abstract

The invention discloses a method for acquiring a target depth image. The method includes steps of applying at least two working modes, and collecting targeted image information at the same time; respectively processing the collected image information and further acquiring at least two depth images; comparing detailed information of at least two depth images, outputting the depth image with few detail defaults as the targeted depth image, wherein the first working mode uses two RGB vidicons; the second working mode uses an IR vidicon and a laser projector. Through the method, the accuracy and convenience of acquiring the target depth image can be improved.

Description

technical field [0001] The invention relates to the field of 3D technology, in particular to a method for acquiring a target depth image. Background technique [0002] With the continuous development of 3D technology, it becomes easier to obtain the target depth image, and the traditional image analysis using planar image has been gradually transformed into image analysis using depth image. In order to ensure the accuracy of the analysis, the quality requirements of the acquired target depth images are getting higher and higher. [0003] Due to the difference in the scene where the target is located, for example, there is a large scene difference between an indoor target and an outdoor target, and most of the current 3D sensors are not suitable for multi-scene applications. Due to the scene difference, the obtained depth image There is an error. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a method for acqu...
