How To Choose The Right Lidar Sensor For Your Project Choosing the right technology for cad drafting for cad drafting, the decision between lidar and photogrammetry often comes down to: required precision: if high precision and detail are paramount, lidar is typically the better choice. budget constraints: if cost is a major factor, photogrammetry offers a more budget friendly option. Definition of photogrammetry. photogrammetry is a practice where measurements between objects are determined through the use of photographs. in literal terms: “photo” means light. “gram” means drawing. “meter” refers to measurement. simply put, it’s using light (in the form of photographs) to measure and draw.
Choosing The Right Technology Lidar Or Photogrammetry For Accurate Lidar may be more appropriate for applications such as land surveying and construction, while photogrammetry may be more appropriate for applications such as cultural heritage preservation and visual effects in film and video games. ultimately, both lidar and photogrammetry have their own strengths and weaknesses, and the choice between them. Light detection and ranging (lidar) is known for its high precision in capturing elevation data. while lidar can achieve a vertical accuracy of up to 5 15 cm, horizontal accuracy is up to 10 30 cm (1) (2) (3). lidar achieves this level of accuracy because it uses laser pulses. it directly measures the distance between the sensor and the ground. Presenter david fagermanthis webinar will provide information on how lidar and photogrammetric data collection methods have radically changed over the past. Lidar uses laser pulses to measure distances, while photogrammetry relies on images captured by cameras. consequently, lidar can provide more accurate elevation data and is better suited for surveying areas with complex terrain or dense vegetation.

Lidar and photogrammetry are fundamentally different methods of gathering data. with lidar you end up with thousands of data points that form a 3d point cloud outlining the terrain in question. you’ll need to incorporate colour from separate datasets to turn it into something visually accessible. Key differences: accuracy and precision. one of the primary distinctions between lidar and photogrammetry is their accuracy and precision. lidar excels in capturing highly accurate elevation data, especially in environments with dense vegetation or complex terrain. its ability to penetrate foliage and accurately measure ground elevation makes.
