IPC: G06T17/00
Filed: 1994-02-07
Abstract: PURPOSE:To provide a topographic display device which can reduce the processing frequency of the three-dimensional digital topographic data consisting of meshes and also can shorten the processing time of the topographic data to attain the fast topographic display by processing previously the necessary topographic data and storing a parameter showing the topographic shading state against the topographic data. CONSTITUTION:The topographic data are supplied from a data base managing device 1 which stores the three-dimensional digital topographic data, and the normal vectors are calculated for each triangle including six lattice points. A transforming device 6 transforms the normal vectors into a parameter that shows the topographic chading state by synthesizing and normalizing the normal vectors. Then a display data storing device 7 stores the topographic data. The device 6 calculates a parameter to show the shading states of the topographic surfaces and stores the parameter in the device 7 together with the topographic data. Thus it is possible to reduce the access frequency to the device 1 and also to reduce the calculating frequency of the parameter showing the shading states of the topographic surfaces. Then the fast three-dimensional topographic display is attained.

Filed: 1984-01-31
Abstract: PURPOSE:To simplify control and to make the whole device small-sized by reading in a lump address information contained in position information depicted in each section of a track mark of a floor surface, and information of a track mark position. CONSTITUTION:When a self-running car reaches a position where position information 26 of a section 25a is depicted, a photoelectric detecting device 28 detects head information 31 and sends it out to a correlating circuit 34. The information 31 coincides with head information of a ROM37, therefore, the circuit 34 outputs a coefficient of correlation having the maximum value 1. A main controlling circuit 36 which has received it stores address information 32 read by the device 28 of that time and the information of a position of a mark 25, in a RAM35. Thereafter, the information of the mark position is read out, a position shift from the track mark 25 is calculated, and on the basis of this calculation, a position correcting command signal is sent out to a steering controlling circuit 38. Also, the information 32 is read out of the RAM35, and trasnmitted as the present position information to a receiver 41 of a movement controlling circuit 40. Therefore, the track correction and present position detection of the self-running car can be performed simultaneously and easily.
