Real-Time Object Detection by Stefan Hintersser running on linux Intel X86

Computer Version is an interesting topic, I found an implementation of real-time object detection which is really work on my linux X86.

Stefan Hintersser home page
http://campar.in.tum.de/Main/StefanHinterstoisser

Document
http://campar.in.tum.de/personal/hinterst/index/project/CVPR10.pdf

Although the author says it can work on linux but not really tested.
Now, let's do some fix to get it work.

1.Download and install source code and all necessary libraries

Source code
http://campar.in.tum.de/personal/hinterst/index/downloads.html

OpenCV

ESM
ftp://ftp-sop.inria.fr/evolution/malis/software/ESM/ESMkitLin_0_4.tar.gz
Install in
$DOT_vs_1.0/resources/ESM/ESMkitLin

Intel IPP
I'm running with Intel IPP 6.0.1.071. it installed in /opt

1.Create Makefile

CC=gcc
AR=ar

CFLAGS=-Wall -O3 -funroll-loops -msse2 -I./include -I/usr/include/opencv -I/opt/intel/ipp/6.0.1.071/ia32/include -I./resources/ESM/ESMkitLin/inc
LDFLAGS=-L/opt/intel/ipp/6.0.1.071/ia32/lib -lcv -lcvaux -lhighgui -lcxcore -lippcvmerged -lippmemerged -lippmmerged -lippccmerged -lipprmerged -lippiemerged -lippimerged -lippsemerged -lippsmerged -lippsrmerged -lippcore -lm

LIBS=src/cv_camera.o src/cv_utilities.o src/cv_esm.o

%.o : %.cc
        $(CC) -c $(CFLAGS) $< -o $@

all : main_dot2D main_dot3D

main_dot2D : ${LIBS} src/main_dot2D.o
        ${CC} -o $@ ${LIBS} src/main_dot2D.o ${LDFLAGS} resources/ESM/ESMkitLin/lib/ESMlib.a

main_dot3D : ${LIBS} src/main_dot3D.o
        ${CC} -o $@ ${LIBS} src/main_dot3D.o ${LDFLAGS} resources/ESM/ESMkitLin/lib/ESMlib.a

clean :
        rm -rf src/*.o

2.Then make.
After successful compile and link
run ./main_dot2D

The program almost eating all CPU resource and window shows nothing.
I found the camera frame rate seems too high (90 fps !!!)
So I try to reduce the frame rate by change

        int l_key = cvWaitKey(1);

to

        int l_key = cvWaitKey(60);

Now it's worked ...

Rowboat Android Overlay Setup

There are some trick to setup omap overlay

1. omap_vout omap_vout: probed for an unknown device

To fix this problem set u-boot environment variable

setenv optargs 'init=/init omapdss.def_disp=dvi omapfb.mode=dvi:1280x1024MR-16@60 vram=4M omapfb.vram=0:4M'

http://groups.google.com/group/beagleboard/browse_thread/thread/ff11355c5834a187

2.TIDmaiVideoSink params

Make sure what video output you are using ...

gst-launch-0.10 -v videotestsrc ! TIDmaiVideoSink videoStd=VGA videoOutput=DVI sync=false

gst-launch-0.10 filesrc location=/sdcard/video.mp4 ! typefind ! qtdemux name=demux demux.video_00 ! queue ! TIViddec2 ! TIDmaiVideoSink videoStd=VGA videoOutput=DVI sync=false

3.Resolution issue

try to add these option in your kernel command line: vram=XXX
for example for 1280x1024MR-16@60 you should add vram=4M
1440x1050MR-16@60, vram=6M
1600x1024MR-16@60, vram=7M
etc, the equation to calculate the vram value is x_res*y_rex*4

Android 心得感想

還記的一年前Android大張旗鼓出現,偶當時也具有高度的興趣,因為base on linux而且open source.
而且google也在Android上導入open source所缺乏的重要軟體,例如Web Browser, 穩定的Java VM等.
這一年來偶接觸過兩個Android platform分別是TI OMAP 3530 & Samsung S3C6410, 軟體的部份有修改一些driver以符合Android的要求,簡單的JNI及Android application.偶嘗試以技術的角度將這些與Android的經歷紀錄下來.

1.Linux kernel

Linux kernel必須加上一些Android fix & driver才能跑Android.
例如,比較奇特的像是pmem driver,用來保留memory給Android使用.
坦白說為了特定application保留memory這件事偶個人覺得非常不妥,
一般都是保留給其他hardware使用像是DSP而且也不需要額外的driver來處理,
只要在kernel param設定mem=XXX就能保留剩下的memory,甚至是保留特定memory region也可透過類似方式達到.是效率或著是security issue非得用如此的作法不可嗎 ?

這只是冰山一角,還有其他特異的程式碼在系統中運作著.
事實上Linux Kernel的維護者已經在年初宣佈移除所有Android相關的程式碼.

2.Where is linux ?

第一次順利booting kernel啟動Android進入console之後偶發現一切都很陌生.
是的,的確有個shell,很難用的shell... OK,Android自己搞的shell.

每個指令的功能都陽春到不行,backspace & tab key都不能用.進入/etc目錄之後更是大吃一驚,在UNIX系統沿用多年的許多系統檔案都不見了,全部被Android一手包辦.

在Android 中init.rc這個檔案負責系統初始化的設定,如mount file system, init network 及週邊初始化.其中的script語法並非shell script而是Android自訂的key word所組成.

嗯,這真的不是Linux更不是UNIX like system.
Android是以linux kernel為核心基礎也僅只於此了.

3.Porting Android

Android 具有跨平台在不同CPU上工作的能力,但porting的工作則是各憑本事.
目前Embedded ARM CPU往往有許多特殊硬體的功能,例如2D, 3D graphic engine, video coder及camera interface等.

這些功能在linux kernel driver端常常就有許多新增的ioctl及操作流程,porting的困難是需要對driver及Android都有相當程度的了解才能進行的下去.

在開發環境上以往熟悉的Makefile已經被Android.mk取代,完全不同於傳統Embedded System.

Android對自身系統設計的文件並不多,但光從source code的量來看要能有詳細的文件確實是很難.
所以想要porting Android到產品等級絕對不是幾個有經驗的工程師就能作到其中的know how真的非常多.

4.Java VM

Android提供一個Java VM Engine - dalvik,我相當喜歡這樣的設計.dalvik提供一個可以達到同一個application java binary在不同平台執行,而且其效能不見得比native binary來的差.不過這不是絕對的,例如Android允許使用JNI的方式撰寫直接控制硬體或是連結close source binary.許多商業軟體就會透過這種方式達到保護自身利益.java binary跨平台的特性也因此弱化了.但不可否認的是使用Java 單一語言來開發application的確是很大的好處,尤其是Graphic Interface.如果是c/c++因為語言開放特性的關係就算有完整library也不是一件容易的事(例如QT, gtk).

Maemo 5 DBus 初探

DBus 在Maemo 5系統中是很重要的 IPC 功能,透過DBus可以控制許多硬體如LED, Keypad,甚至是撥電話及發簡訊.現在我想要在程式執行時LCD panel不要進入power saving而關閉也需要透過DBus.

1.Reference

http://wiki.maemo.org/Documentation/Maemo_5_Developer_Guide/DBus/DBus_Basics

http://maemo.org/api_refs/5.0/5.0-final/mce-dev/dbus-names_8h.html#c9f233f336f9be78f223a31866455b80

http://www.mail-archive.com/maemo-developers@maemo.org/msg01889.html

2.以下的程式碼片段就是我想要的囉

    DBusConnection *conn;
    DBusMessage    *msg = NULL;
    DBusError       dbus_error;
    dbus_bool_t     dresult;    

#define MCE_SERVICE                     "com.nokia.mce"
#define MCE_REQUEST_PATH                "/com/nokia/mce/request"
#define MCE_REQUEST_IF                  "com.nokia.mce.request"
#define MCE_PREVENT_BLANK_REQ           "req_display_blanking_pause"

    dbus_error_init(&dbus_error);
    
    conn = dbus_bus_get (DBUS_BUS_SYSTEM, &dbus_error);

    msg = dbus_message_new_method_call(MCE_SERVICE, 
                                       MCE_REQUEST_PATH,
                                       MCE_REQUEST_IF, 
                                       MCE_PREVENT_BLANK_REQ);
    if (msg == NULL)
        return;
    
    dresult = dbus_connection_send (conn, msg, NULL);

    if (!dresult) 
    {
        dbus_message_unref(msg);
        return;
    }
   
    dbus_connection_flush(conn);
    dbus_message_unref(msg);

Maemo 5 debian packaging

初次嘗試Maemo 5 hello world programing之後,將binary複製到target上就可以執行.
但這樣並不是正規的散布方式,Maemo 5支援Debian dpkg的方式包裝binary,包含icon, desktop設定等...
網路上搜尋Maemo 5 dpkg相關的資料並不多,流程也有些複雜,因此作個紀錄供往後參考用.

以下將延續之前的example_hildonprogram

1.要使用dpkg packaging需要配合autotools (據說也可以不要)
2.建立目錄及環境,之後複製example_hildonprogram.c

[sbox-FREMANTLE_ARMEL: ~/] > mkdir example_hildonprogram
[sbox-FREMANTLE_ARMEL: ~/] > cd example_hildonprogram
[sbox-FREMANTLE_ARMEL: ~/example_hildonprogram] > mkdir src
[sbox-FREMANTLE_ARMEL: ~/example_hildonprogram] > mkdir data
[sbox-FREMANTLE_ARMEL: ~/example_hildonprogram] > mkdir data/maemo

複製example_hildonprogram.c 到 example_hildonprogram/src

3.建立autotools所需檔案

File configure.ac

AC_INIT([example_hildonprogram], [0.1])
AM_INIT_AUTOMAKE([foreign])
AC_PROG_CC
PKG_CHECK_MODULES(GTK2,
        [gtk+-2.0]
        [AC_SUBST(GTK2_CFLAGS)
        AC_SUBST(GTK2_LIBS)])

PKG_CHECK_MODULES([HILDON], [hildon-1 >= 2.2])
AC_CONFIG_FILES([Makefile src/Makefile])
AC_OUTPUT

File Makefile.am

SUBDIRS = src
EXTRA_DIST = data/icons/example_hildonprogram.png \
        data/maemo/example_hildonprogram.desktop \
        data/maemo/com.nokia.example_hildonprogram.service

File src/Makefile.am

bin_PROGRAMS = example_hildonprogram

example_hildonprogram_SOURCES = example_hildonprogram.c

example_hildonprogram_CFLAGS = $(GTK2_CFLAGS) \
                $(HILDON_CFLAGS)

example_hildonprogram_LDADD = $(GTK2_LIBS) \
                 $(HILDON_LIBS)

4.建立Maemo 5所需檔案

File data/maemo/example_hildonprogram.desktop

[Desktop Entry]
Encoding=UTF-8
Version=0.1
Name=example_hildonprogram
Type=Application
Exec=/usr/bin/example_hildonprogram
Icon=example_hildonprogram

File data/maemo/com.nokia.example_hildonprogram.service

[D-BUS Service]
Name=nokia.com.example_hildonprogram
Exec=/usr/bin/example_hildonprogram

5.Run autoreconf to create configure

[sbox-FREMANTLE_ARMEL: ~/example_hildonprogram] > make dist
{ test ! -d example_hildonprogram-0.1 || { find example_hildonprogram-0.1 -type d ! -perm -200 -exec chmod u+w {} ';' && rm -fr example_hildonprogram-0.1; }; }

9.解開壓縮檔準備以此作為packaging source,這樣的作法不會影響到原來的source.

Type of package: single binary, multiple binary, library, kernel module or cdbs?
[s/m/l/k/b] s

Maintainer name : unknown
Email-Address   : stevegigijoe@yahoo.com.tw
Date            : Mon, 9 Aug 2010 15:47:56 +0800
Package Name    : example.hildonprogram
Version         : 0.1
License         : gpl
Type of Package : Single
Hit to confirm:
Done. Please edit the files in the debian/ subdirectory now. example.hildonprogram
uses a configure script, so you probably don't have to edit the Makefiles.

11.packaging

首先更動一下 debian/control, 這個檔案很重要.

[sbox-FREMANTLE_ARMEL: ~/example_hildonprogram/example.hildonprogram-0.1] > vi debian/control

-Build-Depends: debhelper (>= 5), autotools-dev
+Build-Depends: debhelper (>= 5), autotools-dev, libhildon1 (>= 2.2)

OK,go packaging

以下兩者都可以
dpkg-buildpackage -i -rfakeroot -D
dpkg-buildpackage -sa -rfakeroot -kstevegigijoe@yahoo.com.tw
