Abstract: The present invention provides a method of making 1,1,1,2,3-pentachloropropane comprising: (1) utilizing 1,1,1,3-tetrachloropropane as a raw material and 1,1,1,2,3-pentachloropropane as a solvent to carry out a dehydrochlorination reaction to obtain 1,1,3-trichloropropene, and after the reaction, (2) introducing chlorine gas into the reaction system to carry out a chlorination reaction to obtain 1,1,1,2,3-pentachloropropane. In the present invention, 1,1,1,2,3-pentachloropropane acts as a solvent or a diluent, and may act as an inhibitor to prevent the production of high-boiling residues such as dimers, oligomers or polymers during the dehydrochlorination process. Then, the conversion rate of 1,1,1,3-tetrachloropropane is increased, and consequently, the yield of final product 1,1,1,2,3-pentachloropropane is also increased.

Abstract: The present invention discloses a method for modeling and registering 3D scene structure based on single image, belonging to the field of virtual reality technology. The method includes calibrating camera through analyzing image line features; analyzing property of plane support relationship by using categorized lines to obtain a preliminary scene structure; optimizing scene structure via interoperation by a small number of users to complete modeling of scene structure for whole image; and finally registering 3D image scene structure, collected by different cameras through line features, into a unified 3D scene, allowing application into modeling of wide-range scene structure. According to the present invention, corresponding information of 3D scene structure can be rapidly obtained through interoperation by a small number of users.

Abstract: The invention provides a light field illuminating method, device and system. The method includes: determining, based on position and angle of rays emitted from a projector and focal length of a lens, position and angle of projection rays obtained after the emitted rays being transmitted through a lens array; determining, based on position and angle of projection rays and light probe array of sampled scene, brightness value of projection rays; converting, based on brightness transfer function of projector, brightness value of projection rays into pixel value of projection input image, generating projection input image based on pixel value of projected input image; and performing light field illumination on target object with projection input image.
