Laser + Camera = Innovation

Reliable Automatic Camera-Laser Calibration

Camera-laser calibration is necessary for many robotics and computer vision applications. However, existing calibration toolboxes still require laborious effort from the operator in order to achieve reliable and accurate results. This paper proposes algorithms that augment two existing trustful calibration methods with an automatic extraction of the calibration object from the sensor data. The ...

Using a Camera Phone as a Mixed-Reality Laser Cannon

Despite the ubiquity and rich features of current mobile phones, mobile games have failed to reach even the lowest estimates of expected revenues. This is unfortunate as mobile phones offer unique possibilities for creating games aimed at attracting demographics not currently catered for by the traditional console market. As a result, there has been a growing call for greater innovation within ...

Camera-guided Feeding of Optics in Robot- based Laser Assembly

Optics and laser technology are sectors in high technology with significant perspectives for the near future. Especially, photonics industry is regarded to be highly innovative and new products are developed and brought to market frequently. Once photonics has established a product, the production often migrates to countries with low labor costs. This is caused by the fact that production proce...

Tracking Multiple Moving Targets using a Camera and Laser Rangefinder

Extrinsic Calibration of a Camera and Laser Range Finder

We describes theoretical and experimental results for the extrinsic calibration of sensor platform consisting of a camera and a laser range finder. The proposed technique requires the system to observe a planar pattern in several poses, and the constraints are based upon data captured simultaneously from the camera and the laser range finder. The planar pattern surface and the laser scanline on...
