Intelligent Vision Systems Lab The IVS Lab is known for providing vision‑based solutions for businesses, innovators and entrepreneurs across New Zealand and the world. We specialise in: - 3-D Reconstruction - Convolutional Neural Networks - Machine Learning - Object Recognition - Virtual Reality - Augmented Reality - Image Processing - Photogrammetry - Camera Calibration Established in 2005, with over 1000 publications, the IVS Lab is a leading authority in the field of Computer Vision. The current focus of the group is to combine hardware, algorithms and machine learning to form useful systems that can measure the geometry, topography and the composition of scenes at various scales and resolutions.
What we offer We specialise in: • 3D reconstruction • convolutional neural networks and machine learning • object recognition • virtual reality (VR) • augmented reality (AR) • image processing • photogrammetry • camera calibration. We have developed systems for LIDAR calibration, smartphones, Raspberry Pi, NVidia Jetson, Kinect, Asus Xtion, GoPro Cameras and others. We specialise in combining multiple cameras and sensors to acquire optimal results through sensor consistency.

THINKPASTURE
MOBILE TURNTABLE
Effective pasture management is an important component in ensuring optimal quantity and quality in dairy yields in New Zealand.
3D models are in high demand for computer graphics, virtual reality (VR), augmented reality (AR) and 3D printing. Hand-held professional 3D scanners are expensive and often limited to a small objects, effectively putting high-quality 3D models out of reach for small businesses and hobbyists. Cheaper solutions often leave users frustrated with tracking problems and low resolution models.
We’ve developed ThinkPasture, a system that converts a simple smartphone into a handheld dry matter measurement tool enabling dairy farmers to easily assess pasture quality. Testing has shown it can distinguish between four common New Zealand grass types with 96 per cent accuracy. The system uses GPS, IMU and the camera of a typical smartphone to effectively track pasture measurements over time. The technology behind this tool can be applied to other types of farming, since the system can easily be extended to identify the type and condition of any plant matter that can be imaged with a smartphone. The system can also function off-line in regions with no mobile coverage and correctly in regions with no GPS coverage.
Our solution uses a simple wooden turntable, a printed pattern and a webcam attached to a mid-range laptop. It can scan sufficiently textured objects to an accuracy of 1mm. Objects with little texture may also be scanned at a similar resolution with the addition of a simple mini LED projector.
UAV MAPPING SOLUTIONS Unmanned Aerial Vehicles (UAV) have become popular for their ability to acquire images from a unique perspective. The technology is used to build maps of regions using various types of cameras. These maps are important for many applications, including changes in the distributions of flora and fauna, erosion patterns, and recording significant structures. We have developed a SLAM system (simultaneous localization and mapping) that acquires the geometry of scenes below one square kilometre with centimetre resolution, based on the images acquired from a custom-designed Raspberry Pi stereo camera rig. The IVS Lab also has worked on combining multi-scale outputs from LIDAR systems, thermal cameras and multi-spectral systems to create maps of scene geometry augmented with several channels of data, allowing for sophisticated object detection and scene understanding.
