Embodiment Construction

[0082] In order to facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element, or one or more intervening elements may be present therebetween. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The terms "upper", "lower", "inner", "outer", "bottom" and other terms used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention. The invention and simplified description do not indicate or imply that the device or element refe...

Abstract

Embodiments of the present invention relate to an evaluation method, evaluation system and testing equipment of a stereo matching algorithm. The evaluation method includes: acquiring three-dimensional information and a planar image of a sampling area; determining the corresponding relationship between the planar image and the three-dimensional information according to several calibration parameters; using a stereo matching algorithm to calculate a depth estimate of the planar image value; determine the evaluation result of the stereo matching algorithm according to the comparison result of the estimated depth value and the corresponding three-dimensional information. This method uses the camera that captures the depth information and the preset calibration parameters to directly obtain the actual depth information in the current use environment as a reference, avoiding the limitations of the public data set, and making the evaluation results closer to reality.

Description

【Technical field】 [0001] The invention relates to the technical field of image processing, in particular to an evaluation method, an evaluation system and a testing device for a stereo matching algorithm. 【Background technique】 [0002] The basic task of the stereo matching algorithm is to find out the correspondence between different image information obtained from different viewing angles, and each pixel point. On the basis of knowing these correspondences, the disparity information can be easily obtained by using the principle of binocular stereo vision, so as to further obtain the depth and stereo information of the original image. [0003] With the continuous development of technology, many different stereo matching algorithms have emerged. These stereo matching algorithms have their own corresponding applicable data scenarios and sensor hardware. How to choose an appropriate algorithm among a large number of stereo matching algorithms and quickly complete parameter t...
