The development of PC desiderates exact information gained by RS rapidly (Moran et al., 1997), hyperspectral technology which acts as the hot and frontier of RS in the world, is showing outstanding potential in agriculture because of its ability not only to monitor crop and some of its surroundings timely, nondestructively in a big area as the normal RS technology does, but also improve the classification precision and accuracy of agriculture resources and supervise and analyses crop growth and the factors related with crop yield by spectral precision predominance.

精确农业的发展迫切要求遥感技术提供快速、准确的地表信息（Moran等，1997），高光谱遥感技术作为国际遥感科学领域的研究前沿和热点，由于其既具备常规遥感对农作物及其生长环境监测的大面积、适时、非破坏性等优点，同时又能够通过其精细光谱优势提高农业的分类的精度和准确性，动态地监测和分析作物的健康状况与影响作物产量的环境因素，因此其在农业领域已表现出非凡的研究潜力。

The estimation of additive and dominance effects through QTL analysis by onedimensional search while ignoring epistases showed similar accuracy to that by two-dimensional search by including epistases. Existence of epistases could decrease the precision for the estimation of additive and dominance effects. The estimation of genetic main effects would be biased if ignoring the interaction effects of QTL×environment . Joint analysis of multiple environments including QE interaction effects could increase the precision for the estimation of genetic main effects.

The camera calibration method is based on the 2D plane target\'s camera calibration method that is proposed by Zhang Zheng-you et al. Intrinsic and extrinsic parameters of fixed-focus camera are obtained and the precision and the error analysis of Camera calibration are done. The multi-sensor vision system errors are obtained. The error average value is 3.39 mm in X lateral, 0.43 mm in Y lateral, and 1.52 mm in Z laterals. The precision might satisfy the multi-sensor vision system\'s localization request.(3) The goal position and intensity have difference between the visible light image and the near-infrared image because of their image formation mechanism, resolution and field of view differences.
