rfid triangulation

. (1) How to represent a model There are two types of model representation, one is expressed by equation and one is represented by solid modeling. The equation representation mainly includes common curved surface equations, Bezier curved surfaces, B-spline curved surfaces and nurbs curved surfaces. Solid modelling means that there are a lot of content, such as boundary Representation, Space division representation, and many more. In summary, the main task of this part is to represent an entity i

The problem of triangular gridding (triangulation) of arbitrary point sets has always been a close concern of people. The problem of triangular meshes is widely used in many fields. Delaunay triangulation is the most widely used method of dissection, because of its many advantages, the following simple list of two: Null Circumcircle property: In a D-triangular network generated by a point set V, the circum

Compared to Orb-slam, it eliminates the function of loopback detection and relocation, does not seek to establish, maintain a global map, more value tracking effect, the pursuit of high computational speed, low CPU occupancy, so SVO is ideal for use on mobile devices with limited computing r

technology In addition to the above-mentioned mainstream wireless communication technology, the existing wireless communication technology also includes: IrDA, Bluetooth, RFID, UWB, trunking communication and other short-range communication technology and LMDS, MMDS, point-to-point microwave, satellite communications and other long-distance communication technology.

distinct child patterns; The position of each child pattern in the reference image is predetermined (the design of the reference pattern includes the design of the child pattern and the position ID of the child pattern in the reference pattern). You can think of a lookup table that has the ID and position of each child pattern in a reference pattern: The position of the child pattern ID in the reference pattern (or it can be an equal angle, depending on how the

Millions of of the data in the database, processing may be slow, so it is simple to build a smaller structure of similar tables, test data /* 0 */ { "_id": ObjectId ("54fe73e36e26d21dc4391bdb"), "Create_date": Isodate ("2014-07-26t13:57:18z"), "Rfid_no": "010101000120140322000173" } /* 1 */ { "_id": ObjectId ("54FE74076E26D21DC4391BDC"), "Create_date": Isodate ("2014-07-24t11:57:18z"), "Rfid_no": "010101000120140322000173" } /* 2 */ { "_id": ObjectId ("54FE74136E26D21DC4391BDD"),

Use Teensy to simulate the e-mapreduce x card and crack the feasibility of the e-mapreduce X-class access control system. The previous day, Open started Teensy ++ 2.0. Therefore, we studied Teensy ++ 2.0 simulation eminix and conducted a brute-force cracking test on the access control of eminix, the following is the relevant code and content.What is low frequency? What is emedia X? First, I have to mention those low-frequency cards that work at a KHz frequency (for example, emstmx) so that you c

The following is an explanation of low frequency: Low freq

At the last summit forum, I talked with some bloggers about the two hot topics of IOT and smart planet. During the conversation, I found that from a technical point of view, there are many similarities between the two, and this article is a summary of that sentiment. This article will first introduce the concepts of IOT and smart planet, and then introduce the technical differences between the two and their relationship with cloud computing. Iot The Internet of Things (IOT) is abbreviated as "th
