A novel algorithm for distance measurement using stereo camera
CAAI Transactions on Intelligence Technology, 2022 Distance estimation can be achieved by using active sensors or with the help of passive sensors such as cameras. The stereo vision system is generally composed of two cameras to mimic the human binocular vision. In this paper, a Python‐based algorithm is

Experiments on mobile robot stereo vision system calibration under hardware imperfection
MATEC Web of Conferences, 2018 Calibration is essential for any robot vision system for achieving high accuracy in deriving objects metric information. One of typical requirements for a stereo vison system in order to obtain better calibration results is to guarantee that both cameras

ACCURACY EVALUATION OF STEREO CAMERA SYSTEMS WITH GENERIC CAMERA MODELS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. In the last decades the consumer and industrial market for non-projective cameras has been growing notably. This has led to the development of camera description models other than the pinhole model and their employment in mostly homogeneous camera systems.

Practical Intraoperative Stereo Camera Calibration
, 2014 Many of the currently available stereo endoscopes employed during minimally invasive surgical procedures have shallow depths of field. Consequently, focus settings are adjusted from time to time in order to achieve the best view of the operative workspace.

A Novel Solution for Camera Occlusion in Stereo Vision Technique
Advances in Mechanical Engineering, 2013 Stereo version is a well-known technique for obtaining depth and surface information of objects from images captured by two cameras. In general, this technique is limited by camera occlusion inherent to grooved or steep profiles in 3D shape measurements.

Hourglass 3D CNN for Stereo Disparity Estimation for Mobile Robots
Applied Sciences, 2023 Stereo cameras allow mobile robots to perceive depth in their surroundings by capturing two separate images from slightly different perspectives. This is necessary for tasks such as obstacle avoidance, navigation, and spatial mapping.

DPO: Direct Planar Odometry with Stereo Camera
Sensors, 2023 Nowadays, state-of-the-art direct visual odometry (VO) methods essentially rely on points to estimate the pose of the camera and reconstruct the environment. Direct Sparse Odometry (DSO) became the standard technique and many approaches have been developed from it. However, only recently, two monocular plane-based DSOs have been presented.

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.
