In this paper some new methods for determining the sensor orientation of linear scanner images are discussed. The image matching techniques are used for automatic identification, transfer and measurement of the image tie points, which connect all images in the block together. A new and simple sensor model based on direct linear transformation is developed(More)
This paper introduced a new automatic terrain extraction (ATE) module inside ERDAS's photogrammetric software LPS. This method uses a global DEM to initialize a surface model and iteratively refines it with image registration on different pyramid levels. Search range used in image registration is adaptively controlled by elevation range of matched feature(More)
After about 20 years research and development in digital photogrammetric systems, commercial software systems have become more and more powerful and capable of solving most photogrammetric mapping problems. On the other hand, user demands for higher automation and more flexibility for digital photogrammetric systems keep increasing, especially with the use(More)
Tetranychus cinnabarinus (Acari: Tetranychidae) is a worldwide polyphagous agricultural pest that has the title of resistance champion among arthropods. We reported previously the identification of the acaricidal compound β-sitosterol from Mentha piperita and Inula japonica. However, the acaricidal mechanism of β-sitosterol is unclear. Due to the limited(More)
Huping jujube is widely cultivated in northern China. PcPKS5, a resveratrol synthase (STS) gene, contains all functionally divergent plant specific type III PKSs and is involved in resveratrol synthesis. This study aimed to assess the effects of heterologous overexpression of the resveratrol synthase (PcPKS5) gene on Huping jujube (Ziziphus jujuba Mill.)(More)
Most conventional digital photogrammetric systems (DPS) are designed for processing digitized images taken from aerial metric cameras and intended for users with strong photogrammetric background knowledge. On the other hand the geo-spatial information from remotely sensed images taken from various kinds of cameras are now more applicable and accessible for(More)
