Specifically, for the geometric center point C of each unit three-dimensional model, the 3D KDE algorithm can calculate the viewing density value of the center point by using the relationship between the peripheral coordinates of the peripheral points contained in the geometric center point C and the distance and time of the center point:
wherein x isi,yi,tiIs a peripheral coordinate, i.e., a three-dimensional coordinate of an actual house source contained in the unit three-dimensional model, hsIs the bandwidth of the spatial dimension, htIs the bandwidth in the time dimension and,

Here, the frequency is viewed according to the house source zone of the unit three-dimensional model, the unit three-dimensional model is divided into a plurality of frequency sections, corresponding rendering colors are determined for the frequency sections, and the corresponding rendering colors are rendered for the corresponding unit three-dimensional model in the frequency sections. Specifically, according to the steps, the house source zone frequency of watching f (C) of each unit three-dimensional model is calculated, and a house source zone frequency of watching matrix P of the whole house source zone three-dimensional model is generated:
further, the matrix is visualized and different house source band viewings are distinguished in different rendering colors. Wherein, the larger the frequency of viewing in the house source zone is, the darker the color is.
And S206, generating a frequency-watching thermodynamic diagram of the house source belt.
And S207, analyzing the frequency-watching thermodynamic diagram of the house source belt.
In this step, according to the frequency-with-watching thermodynamic diagram of the house resources, the broker may be assisted in verifying the arrangement with watching of the house resources in the specific spatio-temporal domain.
The method for generating the frequency-watching thermodynamic diagram of the house source belt is achieved based on the steps. The method comprises the steps that house source watching data of all house sources in a specific space-time domain are obtained from a client side of broker operation, and the space-time domain divides a house source watching three-dimensional model into a plurality of unit three-dimensional models according to three dimensions of longitude, latitude and time. Further, the in-band density value of the geometric center point of each unit three-dimensional model is calculated through the 3DKDE, and a 3D density matrix is obtained.
