interior point test method PIT (Perfect point-in-triangulation test).The pit theory is to determine if M is in the triangle ABC, if there is a direction, M points along this direction will be away from or close to the three vertices of the triangle ABC, then M is in the triangle ABC, otherwise it is located outside the triangle ABC.2.

operate in a non-enclosed environment, so GPS is not applicable in scenarios such as tunnels. As a supplement, the camera is also used for positioning. To simplify, as shown in Figure 1-5, vision-based positioning consists of three basic steps: ① by triangulation of stereoscopic image, the disparity map is first obtained to calculate the depth information of each point. ② by matching the salient features between frames of continuous stereoscopic ima

direction vector of the midpoint of the human Horn and the center of the head, the coordinate system of the triangle mesh obtained by the handheld scanner depends on the orientation of the first scan, so that the z-axis of the grid has an error with the correct coordinate system.The core method used in this paper is PCA (Principal Component analysis). For the face element adhesion problem of the arm and body, it can be circumvented by the scanning target opening arm, while the high and low shou

A typical A-GPS-enabled authentication er will use a data connection (Internet or other) to contact the specified ance server for aGPS information. if it also has functioning autonomous GPS, it may use standalone GPS, which is sometimes slower on time to first fix, but does not depend on the network, and therefore can work beyond network range. some aGPS devices do not have the option of falling back to standalo

1 INTRODUCTIONIn OpenGL, to make it easier to provide fast rendering of eligible polygons, conditional limits are imposed on legitimate polygons. It is known that the division of Polygon P in space is a series of disjoint polygons that are equivalent to the original polygon p. To maximize performance, solve flicker problems that occur during rotation of concave polygons drawn in three-dimensional space. Based on the study of Cgal triangulation algorit
