A system for the generation of in-car human body pose datasets

Silva, João Pedro Borges Araújo Oliveira; Queirós, Sandro; Oliveira, Bruno; Torres, Helena Daniela Ribeiro; Rodrigues, Nelson; Coelho, Victor

With the advent of autonomous vehicles, detection of the occupants’ posture is crucial to tackle the needs of infotainment interaction or passive safety systems. Generative approaches have been recently proposed for human body pose in-car detection, but this type of approaches requires a large training dataset for a feasible accuracy. This requirement poses a difficulty, given the substantial time required to a...

Automated generation of synthetic in-car dataset for human body pose detection

Borges, João; Oliveira, Bruno; Torres, Helena Daniela Ribeiro; Rodrigues, Nelson; Queirós, Sandro Filipe Monteiro; Shiller, Maximilian; Coelho, Victor

In this paper, a toolchain for the generation of realistic synthetic images for human body pose detection in an in-car environment is proposed. The toolchain creates a customized synthetic environment, comprising human models, car, and camera. Poses are automatically generated for each human, taking into account a per-joint axis Gaussian distribution, constrained by anthropometric and range of motion measuremen...


Top-Down Human Pose Estimation with Depth Images and Domain Adaptation

Rodrigues, Nélson; Torres, Helena; Oliveira, Bruno; Borges, João; Queirós, Sandro; Mendes, José; Fonseca, Jaime; Coelho, Victor; Brito, Jsé Henrique

In this paper, a method for estimation of human pose is proposed, making use of ToF (Time of Flight) cameras. For this, a YOLO based object detection method was used, to develop a top-down method. In the first stage, a network was developed to detect people in the image. In the second stage, a network was developed to estimate the joints of each person, using the image result from the first stage. We show that ...

Real-Time Human Body Pose Estimation for In-Car Depth Images

Torres, Helena R.; Olivreira, Bruno; Fonseca, Jaime; Queirós, Sandro; Rodrigues, Nélson; Coelho, Victor; Pallauf, Johannes; Brito, José Henrique

Over the next years, the number of autonomous vehicles is expected to increase. This new paradigm will change the role of the driver inside the car, and so, for safety purposes, the continuous monitoring of the driver/passengers becomes essential. This monitoring can be achieved by detecting the human body pose inside the car to understand the driver/passenger’s activity. In this paper, a method to accurately d...
