In-Depth Technical Information of Xcitex Software and Hardware


ProAnalyst

Image Processing Brightness, Contrast, Gamma and Exponential

This application note discusses Brightness, Contrast, Gamma and the Exponential/Logarithmic (Exp. /Log.) function settings in relation to image processing with Xcitex ProAnalyst software. This application note details how to control light and dark in images and how these factors relate to video analysis. Also included are explanations of these LUT settings, image palette options and how they affect tracking and building a histogram in relation to image processing.

Image Filtering in ProAnalyst

This application note describes image filtering, a subsection of the overall process of image processing -- manipulating your video to get the highest image quality in order to achieve the best possible tracking results. This is a detailed account of how image filtering works in ProAnalyst. Adding and removing specific filters, modifying filter properties, and a list of available filters are included.

Using the Fixed Length Perspective Calculator in ProAnalyst

The Fixed Length Perspective Calculator is a ProAnalyst tool that calculates a 2-D perspective calibration that minimizes the variation of the distance between two tracked targets across multiple frames in a video. This tool can be useful for golf, baseball, or any application where a known-length object is moving in a flat plane. For example, once the calibration is completed, users can measure angular velocity of the object in the plane or velocity of various points on the object.

Calculating the Velocity of a Ball Moving Toward or Away From a Camera with ProAnalyst

This application note describes a technique for measuring the velocity of a ball moving in a linear path toward or away from a camera. ProAnalyst is used to automatically track the apparent size of the ball as a function of time. This data is exported to an Excel spreadsheet for computation. The user just needs to provide the real diameter of the ball and the distance from the ball to the camera at the first frame of the video.

Building Your Own 3-D Calibration Fixture for use with ProAnalyst

A 3-D calibration fixture is an integral component in the 3-D analysis process. While ProAnalyst is optimized to use a standard Xcitex 2-panel fixture, any arbitrary construct can be substituted, and there is no specific size or configuration that must be used. This document will describe the necessary components an arbitrary fixture must possess, as well as a method for generating a calibration file recognizable by ProAnalyst.

Using the x264vfw Codec with ProAnalyst

H.264 is a new video compression standard that is very popular for compressing video with high quality into smaller file sizes. While Xcitex does not recommend compressing video, many customers have asked about this compression technique. X.264 is an open source implementation of the H.264 standard. This application note describes how to use the x264vfw encoder and decoder with ProAnalyst. This enables ProAnalyst to load and save X.264/H.264 encoded AVI files. Specific software version, configuration, and file saving recommendations are provided for obtaining the best results.

 


MiDAS DA

Measuring Trigger Accuracy with MiDAS DA and an Xcitex MkII LED Box

The new Xcitex LED-2 MkII demo box is a valuable tool for measuring synchronization between cameras and data acquisition systems. This test will visually demonstrate and quantify the accuracy of the event trigger to the '0' video frame of a camera and '0' datum of a data acquisition system. After you have completed the recording, comparing the video and data information will show the accuracy of the MiDAS video/data combination.

Configuring the NI CB-68LP Screw Terminal Block for use with a 40-channel PCI PXI-6225 Board for MiDAS DA

This application note contains charts for wiring National Instruments CB-68LP screw terminal blocks for MiDAS DA hardware. This information applies to National Instruments M-Series device NI PCI/PXI-6255. Connections can be made for as many as 40 differential sensors or 80 single-ended sensors. This documentalso provides instructions for wiring trigger and sync out connections.

Configuring a National Instruments SC2345 50 Shielded Carrier for use with MiDAS DA

For Xcitex customers who wish to use MiDAS DA software with a National Instruments SC2345/50 Shielded Carrier, certain hardware connections are required. This application note describes the hardware connections for installing a National Instruments SC2345/50 Shielded Carrier for use with MiDAS DA.

DAQ Theory for MiDAS DA

This application note discusses Data Acquisition Theory in conjunction with MiDAS DA software from Xcitex. Discussed are such factors as the hardware setup involved with data acquisition, a basic introduction to the various sensor types, understanding the multiplexing process and how it relates to data acquisition.

Configuring the NI 6218-BNC USB DAQ Box for use with MiDAS DA

This application note describes the procedures for installing jumper cables and labels on a model 6218-BNC USB DAQ box from National Instruments for use with MiDAS DA.

Configuring the NI 6216-BNC USB DAQ Box for use with MiDAS DA

This application note describes the procedures for installing jumper cables and labels on a model 6216-BNC USB DAQ box from National Instruments for use with MiDAS DA.

Configuring NI USB BNC Boxes 6221, 6229, 6251, 6259 for use with MiDAS DA

This application note describes the procedure for installing jumper wires and labels on a customer-supplied USB BNC DAQ box from National Instruments for use with MiDAS DA. These instructions apply to models 6221, 6229, 6251, and 6259.

Configuring the NI BNC-2090 Rack Mount Box for use with MiDAS DA

This application note describes the hardware connections for installing a National Instruments Rack-Mounted BNC-2090 terminal block for use with MiDAS DA. While the BNC-2090 is not a standard accessory sold by Xcitex for use with MiDAS DA, it can easily be substituted for the standard BNC breakout box.

Configuring The NI BNC-2110 Breakout Box for use with MiDAS DA

This application note describes the procedure for installing jumper cables and labels on a customer-supplied BNC-2110 breakout box from National Instruments for use with MiDAS DA.

Configuring the NI CB-68LP Screw Terminal Block for use with 62xx M-Series Boards for MiDAS DA

This application note contains charts for wiring a National Instruments CB-68LP screw terminal block for MiDAS DA hardware. This information applies to National Instruments 62xx M-Series devices. Connections can be made for as many as 8 differential sensors or 16 single-ended sensors. This document also provides instructions for wiring trigger and sync out connections.
