Embodiment Construction

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

Abstract

The embodiment of the invention relates to an evaluation method and an evaluation system for a stereo matching algorithm, and test equipment. The evaluation method comprises the following steps: acquiring three-dimensional information and a plane image of a sampling area; determining a corresponding relationship between the plane image and the three-dimensional information according to a pluralityof calibration parameters; calculating a depth estimation value of the plane image by using a stereo matching algorithm; and determining an evaluation result of the stereo matching algorithm according to the depth estimation value and a comparison result of the corresponding three-dimensional information. A camera for shooting the depth information and the preset calibration parameters are utilized, so that the actual depth information under the current use environment can be directly obtained as a reference, the limitation of a public data set is avoided, and the evaluation result is closerto the reality.

Description

【Technical field】 [0001] The invention relates to the technical field of image processing, in particular to an evaluation method, evaluation system and testing equipment of a stereo matching algorithm. 【Background technique】 [0002] The basic task of the stereo matching algorithm is to find out the corresponding relationship of each pixel between different image information obtained under different viewing angles. On the basis of knowing these corresponding relationships, the principle of binocular stereo vision can be used to easily obtain the disparity information, 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 select a suitable algorithm among a large number of stereo matching algorithms and quickly complete para...
