“…Equal Baseline Camera Array was deigned to address the problem with errors occurring on disparity maps obtained on the basis of images from a stereo camera [Kac15,Kac17a,Kac17b]. EBCA preserves all the benefits of a stereo camera however simultaneously EBCA provides higher quality of data than a stereo camera.…”

This paper is concerned with applying a stereo matching algorithm called BP-Layers to a set of many cameras. BP Layers is designed for obtaining disparity maps from stereo cameras. The algorithm takes advantage of convolutional natural networks. This paper presents using this algorithm with a set called Equal Baseline Camera Array. This set consists of up to five cameras with one central camera and other ones aground it. Such a set has similar advantages as a stereo camera. In particular this equipment is suitable for providing 3D vision for autonomous robots operating outdoors. The research presented in this paper shows the extent to which results of using BP Layers are improving because of using the EBCA set instead of a stereo camera.

“…They had a camera matrix build from 16 cameras in 4x4 configuration, however they analyzed the usage of the selected five cameras forming EBCA from the matrix. The author of this paper further developed stereo matching algorithms for EBCA and researched its capabilities [10][11][12]40]. The photo of an operational real EBCA used in the experiments presented in this paper is presented in Fig.…”

“…The disparity of a point p in the reference image is determined regardless of the entire contents of the reference image and the side image. Points of the reference image affecting the disparity of the point p are those that are located in the vicinity of p. The vicinity is called an aggregating widow [12,40]. Aggregating windows may have different shapes and sized.…”

This paper presents a lightweight 3D vision system called Equal Baseline Camera Array (EBCA). EBCA can work in different light conditions and it can be applied for measuring large range of distances. The system is a useful alternative to other known distance measuring devices such as structured-light 3D scanners, time-of-flight cameras, Light Detection and Ranging (LIDAR) devices and structure from motion techniques. EBCA can be mounted on a robotic arm without putting significant load on its construction. EBCA consists of a central camera and a ring of side cameras. The system uses stereo matching algorithms to acquire disparity maps and depth maps similarly as in case of using stereo cameras. This paper introduces methods of adapting stereo matching algorithms designed for stereo cameras to EBCA. The paper also presents the analysis of local, semi-global and global stereo matching algorithms in the context of the EBCA usage. Experiments show that, on average, results obtained from EBCA contain 37.49% less errors than the results acquired from a single stereo camera used in the same conditions.
