We present results from the first systematic, camera-trap study in forest woodland, western Uganda.
We measured that the required orientation accuracy of 0. when moving slowly can be met only when the encountered systematic error in camera pose estimation is ignored: 1 cm at 3 m translates to.
For the systematic error due to camera factors, it is suggested as: calibrating the camera with professional calibration tools before using it in the field; trying to use single-lens reflex (SLR) or better cameras that produce high quality of photos; and using prime lenses instead of zoom lenses whenever possible.
Based on the categories of the error sources - systematic error due to camera factors and systematic error due to poor planning of camera network geometry, it is crucial to take appropriate strategies to minimize the different types of errors.
From the table, the measurement errors associated with photogrammetry can be attributed to two large categories: 1) the systematic error due to camera factors, and 2) the systematic error due to poor planning of camera network geometry, both of which will be discussed in detail in the following sections.
For the image-based system, the systematic error due to camera imperfection can be categorized into three aspects: 1) lens distortion, 2) approximated principal distance, and 3) resolution.
These two are followed by an overview of the fundamental knowledge in the systematic errors due to the camera factors and poor planning of camera network geometry.
For in-depth camera reviews, including systematic testing in facilities for that purpose, we of course recommend dedicated photography sites like DPReview, and we'll post a few more of our favorite sites later in the week.
I'll leave that to great sites like DPReview, where they can take the systematic approach warranted by a major camera like this one.
Once again Mr. von Trier has imagined a stubborn, simple-minded woman who is also the embodiment of selfless, innocent goodness and has trained his digital camera on her utter and systematic annihilation.
In 2015, we sampled a study area of 220 km2 with 60 camera trap locations adopting a systematic grid.
