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.
