Embodiment 1

[0062] A method for obtaining three-dimensional data provided by an embodiment of the present invention can be used for contour modeling of objects in the environment, such as figure 1 shown, including:

[0063] S11: Extracting a region image of the target object through a region threshold method according to the image.

[0064] Specifically, the target object image is extracted through the improved area threshold method applicable to various environments, that is, the object requiring contour modeling in the real-time image is extracted using the improved area threshold method.

[0065] As a preferred solution, read the left real-time image of the binocular camera, threshold the depth map obtained by stereo vision, obtain the ROI area of ​​the target, and extract the target by using the area threshold method of the HSV model.

[0073] A method for acquiring three-dimensional data provided by an embodiment of the present invention may also be an adaptive object contour modeling method for contour modeling of objects in the environment, such as figure 2 shown, including:

[0074] S21: Obtain a color image through acquisition.

[0075] S22: Segment the color image by dynamically adjusting the segmentation threshold based on the region according to the color model and the depth model, and extract the region image of the target object.

[0076] In practical applications, step S22 specifically includes:

[0077] S221: Perform threshold data screening on the depth map of the color image according to the depth model to obtain a target contour.

[0078] To obtain a depth map for real-time graphics, the disparity map of the real-time image can be obtained through calibration, correction, and matching methods in stereo vision, and the depth map can also be obtained according to the principle of three-dimensi...

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and electronic equipment for acquiring three-dimensional data. Background technique [0002] Image segmentation technology has been widely used in various images such as gray and color natural images, medical images, mineral maps and traffic images. Traditional image segmentation methods mainly include threshold method, boundary detection method, region method and so on. [0003] The image segmentation method based on superpixels refers to the process of integrating the similar parts of the image according to a certain similarity criterion, so as to subdivide the digital image into multiple coherent and easy-to-analyze image regions. Effective information for image segmentation, and generally will not destroy the original image information such as object boundaries in the original image. [0004] At present, for obtaining the relevant data of t...
